RV082 port forwarding limited to 30 entries ?

Hello,
we use RV082 as main gateway and need to open/forward around 50 ports to inside. But during setting of the rules I got an error message "The max of Port Range Forwarding is 30 entries. You can't add any more.".
In the online help is explicitely said "4. Click the Add to List button, and configure as many entries as you would like."
How can we setup more than 30 port forwarding rules ?
If it is this a sotfware bug, can this be corrected ?
Regards,
Petr Svoboda

Petr, I agree with tekliu.  I use the UPnP rules with UPnP disabled for all of my port forwarding, unless a range is needed.  They should not cause any more exposure than regular Forwarding rules, and if you use port translation they will reduce your exposure.
The only differences:
Forwarding allows port ranges
Forwarding has a "Port Triggering" section
UPnP allows port translation (because it's only single port at a time, not a range)
UPnP has unlimited entries

  • Linksys X3500 - Port Forwarding (limited)

    Hi everybody!
    We have purchased 3 pieces of Linksys X3500.
    One for us and a couple for an installer (our customer) who wants to make a wireless home network (for a couple of end users).
    I have to tell you that we are a distributor for security systems (Tvcc and so on) in our area (north of Milan) and we have a lot of NVR and DVR on our network we need to put on-line as demos.
    Today i start to configure the Modem/Router and i find no prob since i tried to add "some" port forwarding...
    We have about 60 single ports to configure and the page of device is limited to not more than 15 (customized) slots!!
    I was hoping the device was able to allow me to add more slots but it seams to be not possible!
    How can i do?
    (ps: i don't want to add an external firewall to do it!) 

    I wasn't talking about the algorithm of wireless but the one used for manage the priority of the traffic...(when devices are already connected)
    and if there's an external device (hardware) that can do a better job (like a "Lan Controller" but cheapest).

  • RV082 Port Forwarding or DMZ Configuration Assistance

    Greetings Community,
    I have an RV082 V2 with 2.0.2.01-tm and I am having trouble with getting my Sprint Airvana to connect properly to the mobile service.  Many suggestions I've read on the Sprint forums indicate putting the Airvana in the DMZ generally allows the device to work properly; however, none have the RV series routers for tips on how to do this appropriately.  This device used to work fine behind the RV082, but I reset it one day and it no longer works.
    The Airvana is a femtocell/router device with a WAN port and 3 LAN ports.  If I connect the Airvana directly to my cable modem, I get the appropriate connection and can then make calls through the device instead of through the Sprint connection; I live in a basement unit and get crappy signal without the device.  This proves the device works and that my ISP is not blocking the ports.  Sprint indicates the device uses UDP 53, 67, 68, 500 and 4500.  Their support sucks and they insist I put the Airvana before my router.  I absolutely do not want to use the Airvana as the router.  There are almost no configuration options in the router interface and it needs to be rebooted somewhat regularly, which would drop internet access throughout the house for 10-15 minutes while it reboots and finally establishes an internet connection.
    As soon as put the Airvana behind the RV082, I no longer get the appropriate connection.  I can, however, plug my computer into one of the LAN ports on the Airvana and connect to the internet in general.  I have the router assign a static IP to the Airvana, and tried forwarding the required UDP ports to the IP.  This did not fix the problem.
    I can certainly troubleshoot the port forwarding issues, but I would also like to look into putting the device into the DMZ, if possible.  I've not worked much in this area, so I am unsure how to appropriately configure the router to allow this to happen.  Is it possible to have the Airvana in the router DMZ without having a public IP for the device itself?  It seems this is something that can be done, but I could be mistaken.  If so, how is that done?
    Please feel free to ask any clarifying questions and I thank you in advance for any assistance you may provide.

    I apologize in the delay in getting back to this post; however, it dropped to the bottom of my priority list for a while.  As a workaround, I used the Airvana device as my router temporarily; however, I have the time again and would like to get it setup behind the RV082 again.
    It does not appear the device supports UPnP.  I had that enabled for some other applications already.
    According to http://tinyurl.com/AirvanaPorts I need the following UDP ports open: 53, 67, 68, 500, 4500.  Another suggestion from a Sprint rep was to also open/forward TCP 5060 and 5061.  I have the ports forwarded to the device as shown below and have confirmed the device has the correct IP address.  The device gets a valid internet connection (verified by plugging a computer into one of the LAN ports on the Airvana device; however, it still does not connect to the Sprint service like it should.  I am guessing there is another port and/or the Sprint article has incorrect information.
    To check this, I'm thinking I need to set the device up in the DMZ, but I'm not sure exactly what I need to do for proper configuration.  Is it as easy as enabling the DMZ port and plugging the device in, or are there other settings needed?  Is there anything else I may be missing for the Port Forwarding?

  • Port Forwarding Persists After Deleting Entry/Reboot

    I had ports 80 and 8080 forwarded to my file server that is static @ 192.168.1.51 for a brief time.    I removed the entries in my airport extreme.  It restarted and came up green.  The file server has a software firewall that was turned on over the weekend.   I received flags that inbound requests on 80 and 8080 were being rejected.  
    Confused, I looked at the port forwarding settings in the airport extreme and the entries were gone.   I then power cycled the airport.   The inbound request alerts continued on 192.168.1.52  
    If the port forwarding entry was removed, I wouldn't expect the server to see any more inbound requests.   This is confusing me.    Any thoughts?
    Thanks,
    Jerold

    I havent't had any responses so I am going to document my steps here.   Maybe someone else will benefit.
    I ran shields up (https://www.grc.com/x/ne.dll?bh0bkyd2) to see if the ports were open and they all showed stealth except for port 21.   I did not have port 21 forwarded, but did at one time.   It acts like the airport extreme is not writing/updating the port forwarding table as it is changed.    Ports 80 and 8080 were stealth.    The file surver had upnp on, so I turned that off, but the airport still seems to pass incoming requests to the file server.   They are not responded to, but I get email alerts about the intrusion attempt.  
    I thought the router was supposed to block these incoming requests.   Why would it be forwarding it to the internal ip and alerting the file server firewall?

  • Port forwarding limitations

    Hei all
    I have used the 10 available forwarding slots on my wrt54gl and wonder if there is any possibility to extend the list beyond 10?
    Mvh

    You'll need a 3rd party firmware for that. Then you have more slots in the gui and you can configure even more through scripts.
    Search for wrt54g on wikipedia to find a list of firmwares.

  • Cant get port forwarding working, please help :(

    I bought an airport extreme yesterday, and since then ive been trying to get port forwarding to work. I've set it up before on other routers, and while its always been a hassle, this is the first time where I might just give up and take the router back. I've been searching the boards for solutions, and ive implemented several of them without success, and a call to apple's tech support got me nowhere. Im sure im just using the wrong number or setting somewhere, but I just cant seem to find it.
    One suggestion i read was to set up the routers connection to my modem manually, instead of through dhcp. When I switched from dhcp to manual, i noticed all the prior numbers except dns servers stayed entered, so i wrote down the ones from when it was set for dhcp and typed them in. My manual setup is:
    I.P.: 68.197.191.59
    subnet: 255.255.224.0
    router: 68.197.160.1
    dns: 167.206.245.68
    167.206.245.69
    every other setting i left on the default.
    the dhcp range is 10.0.1.2 - 200
    One entry recommended a static ip. I originally set one up with the dhcp reservation feature, but then another post said your ip should be outside the dhcp range. Not sure if either method is better, but ive set my system with the following static ip:
    i.p: 10.0.1.201
    subnet: 255.255.254.0 (i was unsure what to enter here, so i chose the same as the routers)
    gateway: 10.0.1.1
    in port forwarding i made an entry with 60000 for the 4 public/private tcp/udp and an ip of 10.0.1.201 (i have tried many other port numbers in the odd chance that the one i picked at random might have already been in use)
    I left every other setting on the defaults. The nat settings (a setting im not familier with) is current set for enabled with the default host box above it empty.
    I should mention, my pc is wired to the router. I am using utorrents port checking site, as well as canyouseeme.org. Neither can ever see my port, one simply says not open, the other says connection refused.
    I hope someone out there can help me with this, as the router is great with this one exception, and I'd rather not return it.

    For starters, it's probably not a bad idea to "factory reset" your device since it sounds like you've had a lot of people giving you different advice. This isn't to say that you've been given *bad advice* but, it may make things easier for a trouble-shooter if you start over from a "known" state.
    That said:
    You need to setup manual port mapping. The problem is, when somebody from the outside tries to access your computer, the Aiport (for lack of a better analogy) isn't expecting any visitors; so it turns them away. ---That matches what you are seeing from canyouseeme.org etc...
    Your error was when you "made an entry with 60000 for the 4 public/private tcp/udp and an ip of 10.0.1.201" Essentially all that will do is make a mapping for one port. Port "60,000" which to my knowledge, isn't used by anything.
    You have to tell the Airport specifically what "outside" ports (each and every one) that you want routed to what "inside" ip address.
    I use:
    Public TCP: 22,80,443,27900,13405
    Public UDP: 123,7777-7783, 13405,6881-6999
    Private IP Address: 10.0.1.201
    Private TCP: 22,80,443,27900,13405
    Private UDP: 123,7777-7783, 13405,6881-6999
    This enables: telnet, http, ssh, bittorrent and unreal tournament from the outside and routes ANY AND ALL TRAFFIC from those ports to my PC at 10.0.1.201 on the inside.
    If I ran AIM, or ICQ or one of those things, then you need to add the ports that that system uses to the list also.

  • Port Forwarding, MI424WR

    I'm not even sure I'll give enough information here, because I don't really know what I'm talking about.  However, I've been working with a couple of "technical" people from my office.
    Essentially, I'm trying to connect two devices (Yamaha Disklavier Pianos) over my FIOS connection (for a process called Remote Lesson) and need to utilize port forwarding.  I've tried the instructions on the www.actiontec.com website (Basic Port Forwarding on the MI424WR Verion Fios Router), but have been unable to connect successfully.
    Basically, here's the two things I need to do (cut and pasted from a technical document draft).  Can someone please advise what might be going wrong?   I could also forward the entire "connection" document to someone who might want to take a look at it and get a clearer picture.
    At any rate, here are steps 2 and 3 of the process we're trying to do:
    2. Port Forwarding for Remote Lesson (WAN to LAN)                                    
    - Port 58092 is used in both TCP and UDP by default.                                      
            - Note: You can choose any port unless it has already used.                            
    - Please configure a system to forward the access of this port to Disklavier.    
    3. Release of the port to the Internet (LAN to WAN)                                      
    - If the access of port 58092 is filtered, please release this port in both TCP and UDP.                    
             Note: If your partner has configured another port number, please release that port in both TCP and UDP.      
                                                                  Port setting table
    PORT FORWARDING (WAN TO LAN):  IP Address (original LAN Address)
                                                                    Port Number (origin)
                                                                    Protocol:  Both TCP and UDP
    RELEASE OF THE PORT (LAN TO WAN): Port Number:  Destination or all
                                                                         Protocol:  Both TCP and UDP                  
    Thanks for being patient with a "newbie" - I hope someone can help.

    If you're only trying to connect the 2 devices within your local lan you do not need to do anything with port forwarding.  You would only need to add port forwarding rules if you are going to access the devices from remote sites.
    The below addresses step 2 of your question.
    Step 3 of your question is not needed as the actiontec does not block any port access from the LAN to the WAN
    Step 2  allowing wan to lan access
    If you are doing the latter then you would want to give the device fixed ip addresses, make sure they are out of the dhcp range of the actiontec router.
    Then go to firewall setting
    Select Port Forwarding tab
    Select New Entry
    add the IP address of the device in the Local Host field
    Make sure Forward to Port is set as Same as incoming Port
    Make sure Schedule is set as Always
    Under protocols Select User defined
    Make the service name whatever you want - e.g Piano
    Select new server ports
    Under protocols Select TCP
    Under source port select single
    enter 58092
    Make sure destination port saya Any
    Hit OK
    Select New server ports again and repeat the last five steps for protocol UDP
    then say OK
    Say OK to the Edit port Forwarding rule
    Now you should be able to access the device from the outside WAN

  • FiOS Quantum Gateway - Edit Port Forwarding Entries

    New to FiOS. Installer provided the new Quantum Gateway. 
    Can't seem to figure out how to edit Port Forward entries on this gateway.  Seems I can only add or delete them.  But once created, no way to edit them to change. So to change anything, I have to delete the existing entry and recreate it.  Pain in the ARSE.
    Many other awefull interface usage issues on this gateway.  Definately a lot of room for improvement. 
    ...Also couldn't find anywhere to update firmware, so I'm guessing Verizon has no plans to ever release updates for this gateway...
    Can't Edit DHCP Address Reservations
    Can't Edit Port Foward assignments
    Can't Release Address Reservations
    Can't Convert DHCP Lease to a Reservation AND change the IP you'd like to assign (can convert to a reservation, but only using the IP dynamically assigned originally)
    Can't sort tables
    Sorting appears to always be based on MAC address, can't sort by IP or Name.
    Am I missing something?

    You don't mention what router it is you have.
    If it's the new Actiontec rev I you are quite correct - there is no apparent way to edit PF rules -  totally user unfriendly

  • Port Forwarding with Port Translation RV042, RV016, RV082

    This is a feature request for the Linksys RV series Routers.  Currently, it appears that the Cisco/Linksys RV042, RV082, and RV016 only support port forwarding and 1-to-1 Nat.  One item that I find very helpful with customers is port forwarding with port translation.  I am requesting that this feature be included with a future firmware relase for these RV series routers.
    Here is an example of the request.
    Take an incoming service request on a TCP or UDP destination port and forward it to an internal IP on a different TCP or UDP port.  For example, customer A wants to allow different machines on the internal network to receive Windows RDP connections inbound.  To make PC maintenance identical between the internal machines, the customer does not want to change the listening port for RDP on the individual PC workstations through the Windows Registry.  The customer also does not want to dedicate separate IP's to each machine in a 1-to-1 NAT setup.  The only option is to have remote connections to each of these PC's to use a different destination port.  So, for example, PC one could be reached on TCP port 5151, PC two on TCP port 5152, and PC three on port 5153.  This requres a firewall that is able to translate each of these connection requests to a different internal IP on the default RDP port (TCP 3389).  So, the following setup is required:
    Port Forwarding with Port Translation:
    Router External IP on TCP port 5151 ---> forwarded to PC One's internal IP on TCP 3389
    Router External IP on TCP port 5152 ---> forwarded to PC Two's internal IP on TCP 3389
    Router External IP on TCP port 5153 ---> forwarded to PC Three's internal IP on TCP 3389
    There are several comparable "small business" class router competitors to the RV042, RV082, and RV016 that will perform this port forwarding with port translation process without incident.  Unfortunately, these Cisco/Linksys small business routers will not accomplish this task currently.
    Please implement this feature in a future firmware release.
    Thanks!

    Excellent.  I see this now.  None of our customers actually use the UPNP feature, so we never realized that Port Forwarding with Port Translation features existed on this page along with the ability to enable or disable UPNP.
    Perhaps, in the future, this functionality could be moved to and incorporated into the port forwarding page which seems to be a more logical location.
    In either case I'm very happy to know that this feature is available on the RV's.
    Thanks for your assistance.

    Using a Westell 9100 router and am accumulating these garbage port forwarding entries - see attached jpg

  • WRT54G Delete Port Forwarding Entries

    I have a WRT54G v5 with the latest firmware upgrade.
    While updating my network I decided to delete old entries from the port forwarding table. Every time I try to delete a port entry or the IP address the error checking routines warn me that a blank entry is out of range then replace it with the old entry. This error check does not depend on the Enable check.
    I CAN overwrite the old entries with new and things work OK but I would just like to delete old entries. I have searched the forums here and cannot seem to find anything related to this problem. This is probable trivial since disabling the entry works but I would just like to have the table cleared.
    I have NOT reset the router yet although I'm sure that would work.
    Thank you

    Hi,
    Have you tried leaving the box with the number "0", instead of leaving it "blank", then save the settings?

  • Port Forwarding To Two Macs with Port 22 limitations

    This is another port forwarding/port 22 issue and I've look around and not seen an answer to my specific problem.  I work for a business that has an in-house ad system that runs on a Mac Mini.  I have been accessing that Mac Mini remotely because we set up port forwarding through the Linksys rounter that is at the business using port 22.  This is the only port that works for this connection to the mini and the software.
    We are now adding a second Mac Mini to send the ads to a different set of monitors.  I can't set up port forward to the new mini on the same port so I don't know how to connect to this mini remotely.  Is there a way to get into the first mini through port 22 and then somehow communite to the second one through the first?  Is there another way to do port forwarding...or have the linksys router switch from one mini to the other when a request comes in?  There will only be one remote computer trying to reach either Mac Mini so there will never be simultaneous traffic coming in.  Any help would be appreciated!
    The linksys router is critical to the business becasue a host of other devices are forwarded though it as well.
    Thank you.

    Having set up my IP camera with HH4 successfully, I've now got another one and would like to set it up as well. I gave it a unique, static IP address which my router can see fine. When I try to set up port forwarding, I get a message saying:
    "The game or application you’ve selected conflicts with an application (IP Cam 1) you’ve already assigned to another device. Please remove the other application or select the same device."
    I am not being given the option to select the same device.
    I'm now wondering if port forwarding to two identical devices actually works in principle with HH4? Has anyone else done this?
    If in the Home Hub 4 A you go to
    Advanced Settings
    Firewall
    Port Fowarding
    Manage Games and Applications 
    You get the following statement:
    "Each game or application can be assigned to only one device on your home network"
    I would think that the only way round your problem is to have each Camera running a different application or the same application with a different name.  
    Does the remote browser app need to know the application name  or just the device name ?
    If you think about how Port Forwarding needs to function you need a way whereby  the remote user needs to be able to tell the Hub what Camera to talk to.  

  • EA4500 Max number of Port forwards

    Hi All,
    Background: currently have a WRT320N, thinking of upgrading to an EA4500 assuming ONE feature has been improved: Port Forwarding.
    Scenario: Currently I have a WRT320N router, and while it "does everything we need" it has one limitation that is now getting in the way: limitation on number of forwardable ports.  In the port forwarding panel, it has 15 total rows: the first five rows can be enabled for specificaly named services (SMTP, FTP, etc).  The last 10 rows are fully customizable in that we can set the name, ports and protocol. 
    The problem is that of the 13 total ports I currently need to forward, only ONE of them is listed in that fixed list.  So, sadly, I can only use one of those first five rows.  I've now filled the remaining ten custom rows, and still have need for two additional ports (for now, may need more down the road).
    Trying to get creative, I figured maybe I could just spill over to the Port Range Forwarding page and add a row or two there.  The only problem: it's buggy.  I've found that if the Single Port Forwarding list is filled, then the Port Forwarding Range entries don't work properly.  For example, if I wanted ports 12345 and 12346 forwarded to 192.168.1.5, they work fine with two single port forwarding entries.  However, if I delete those, add two other port lines I need forwarded (the single list being full again), and add a port forwarding range 12345..12346, they don't work properly, ports just are closed. Only the singles work, the ranges don't.
    Question: Has the EA4500 resolved this issue and allow for either more lines (i.e. 20 customizable entries instead of 10), or, better, does it just have an [Add Entry] button to allow for additional rows to be created?  In today's day and age, where one single device (such as an Xbox) can take four rows, a 10-row limit is pretty sparse.  Comparing it to some competitors, for example the D-Link DIR-825 (aging, but still great) allows you to add as many as you want.
    I realize "expensive" firewalls like SonicWall's have virtually unlimited customization, but I don't need many of the additional features and don't want to spend $350 on a "high-end" firewall to solve the problem of needing two more ports open.
    Thanks to any help you can give!

  • Port Forwarding a Range in UC540 NAT

    Hi all,
    I am trying to forward a range of ports (55736-55863 for Synology  Surveillance Station) from the WAN interface to an internal IP on a Cisco UC540.  I'm not great with the CLI so I generally stick to CCA but right now I'm not even sure it's possible with the CLI.
    I've found this tutorial online: http://evilrouters.net/2010/05/25/port-forwarding-a-range-of-ports-on-cisco-ios/
    The first step in the tutorial is to setup a NAT IP Pool (which I *can* do in CCA) but unfortunately, the tutorial tells me to use the IP address of the internal device I want to foward the range of ports to but CCA (and its documentation) tells that the IP address must be on the same subnet as the WAN IP address?
    I tried following the tutorial anyway by telnetting in to the UC540 and entering the following via the CLI:
    UC540 config t
    UC540 ip nat pool PORTFWD 192.168.12.121 192.168.12.121 netmask 255.255.255.0 type rotary
    UC540 access-list 121 permit udp any any range 55736 55863
    UC540 ip nat inside destination list 121 pool PORTFWD
    I can now see the 121 access list in CCA, although it has no Interface or Direction assigned to it?
    Does anyone know if this is possible?  I really don't fancy setting up 127 entries in the NAT table!
    Thanks in advance everyone!

    The range isn't going to work in CCA.  As you are probably aware, CCA has limits to what it can do, even if something can be done in the CLI.
    That being said, I think this is a better write up on how to do this:

  • New network/port forwarding questions

    I just replaced my Airport Extreme with a 1TB TC and set up a primary network (AirNett) and a Guest network (Guest). I added Port Mapping entries for my computers (running Tiger), SlingBoxes and ReplayTVs (which are all ethernet-connected) and I have 1 laptop running Leopard and 1 running Tiger. We also have 2 iPhones.
    The wired devices all seem to connect just fine. Occasionally, there is a delay in the connection (30 sec-1 min), but once it connects, they seem to stay connected.
    The laptops take too long to connect to the AirNett network. If they do connect, it seems that the connection comes and goes. The iPhones have yet to connect to AirNett.
    The Guest network serves all the wireless devices just fine, BUT, it does not allow connections to the Port Forwarding devices.
    So, 2 issues... any ideas about :
    1) why my primary network (AirNett) is not working properly for my wireless devices and
    2) why my Guest network does not allow the Port Forwarding connections.
    TIA for any suggestions.

    That was my point - all my lan ports that use port 80 can point at port 80, and long as the WAN ports point at something else. The trouble is, I am restricted to only using 80,81 and 443 on the LAN side, which limits me to 3 (not counting 8080 for my routers web gui)
    So that means with my two web cams and web gui on my NAS drive, I am unable to log into any other web interfaces on my LAN, unless I log into my router first, disable one port forward and enable another (using the same WAN port of 80 or 81) - which is doable but a PITA..
    This is what is looks like on the router:
    For example, if I change the port from field for the "tranmission" entry to anything but 80 or 81, it will not work, so if I want to get into my torrent gui on my NAS drive I have to disable "cam1" and enable "transmission"
    I checked with my ISP and they are not blocking any ports, so I'm not sure how to get around this, unless I can serve up a page that shows feeds from more than one camera and serve it from one source, ie my router or NAS drive.
