Linksys WRT610N Port Forwarding

I am finding it impossible to set up port forwarding. No matter what I do I remain completely stealthed when I do a port probe via www.grc.com. The only way I seem to be able to open a port is if I enable remote management. When I do that, whatever port I specifiy as the remote management port is then fully open. Obviously, I can't leave a port exposed like this and, anyway, I need to open multiple ports for my purposes.
Is there a bug? Can technical support please help?
Some background: I'm in the UK and I connect to the internet using the Fibre-to-the-cabinet (FTTC) technology. I have a BT supplied modem (Huawei Echolife HG612) which is completely locked (it is BT property) with no ability to log in and change settings. The WRT610N is plugged into the LAN socket of the modem and connects via PPPoE. Everything else works fine.

A firewall does not open or close a port. A firewall blocks or passes transient traffic. Thus if the port is closed on the computer it doesn't matter what the firewall does. The port will never show up as open as long as the port is not in use.

  • WRT610N Port Forwarding Issues

    Hello I am attempting to port forward the WRT610n however I am currently having no luck at all, here are the details of how the network is set up
    It is a WRT610N model ver2.0 router with a Siemens Speedstream 4201 router (connected by full bridge mode via ethernet)
    DHCP reservation is on (with the computer reserved to an IP I want to port forward to)
    I have tried using DMZ as well as Port Range Forwarding, disabling/enabling UPNP, turning off home network defender, using QoS in various ways, SPI firewall being disabled/enabled, Filter Anonymous Internet Requests disabled
    Is there anything else I can try (I am able to provide more details if necessary)
    The error I am actually getting is "error: connection refused"

    Both Internet IP address (under status page and What Is My IP are the same)

  • 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).

  • Linksys router port forwarding suddenly closed

    i have a 54G wireless home router ..... successfully port fowarded an application from a CPU (server).... but after no connection made from the user to the server .....  it suddenly close the application ..... so what i did is to reboot the router in order to refresh the connection ...... 
     Is there any other ways to fix this sudden close of the ports ?  so that i would do anymore reboots on my router
    I really appreciate any help .....

    MTU is the Maximum Transmission Unit. It specifics the largest packet size permitted for Internet transmission. Select Manual if you want to manually enter the largest packet size that will be transmitted. The recommended size, entered in the Size field, is 1500. You should leave this value in the 576 to 1500 range. To have the Router select the best MTU for your Internet connection, keep the default setting, Auto. A larger MTU brings greater efficiency because each packet carries more user data while protocol overheads, such as headers or underlying per-packet delays, remain fixed; the resulting higher efficiency means a slight improvement in bulk protocol throughput. A larger MTU also means processing of fewer packets for the same amount of data But sometimes we have to manually input the size if the router is unable to determine the actual size.
    Now for your second part of the question: Where do you check the external IP address of the router? You have to go to the status page of teh router to check the IP address.  If you have a dynamic IP address from your ISP, then it will change frequently and you wont be able to ping the previous address.
    Also, what is the firmware version on the router?

    i am running a web and mail server from my home computer. i have port 25 and port 80 set to forward traffic to my webserver. port 80 works ok, but according to the linksys log, the linksys router is blocking port 25. My isp is not blocking any ports, and i can send mail from my mail server. how can I get the linksys router to stop blocking incoming port 25? my router setup is: linksys befw11s4 port forwarding: 80 to 80 25 to 25 upnp is enabled upnp forward smtp 25 tcp to port 25 192.168.X.X dmz is enabled for the server's ip.

    First off, DISABLE the dmz!! That opens ALL ports to your pc, you dont want that.
    Second, because you had the pc in the dmz tells me that the router is not blocking port 25, again, in the dmz all ports are open.
    Disable upnp, it will just cause problems and you arent using it anyway.
    Go to :
    https://www.grc.com/x/ne.dll?bh0bkyd2
    Click proceed, enter 25 in the box in the middle, then click user specified custom probe.
    Does it show as stealth?

  • Linksys e1200 PORT RANGE FORWARDING is not working

    I currently have an E1200. I can port forward single ports, but when I attempt to forward a range of ports it doesn't work and there is no error in the log.
    Specifically I am port forwarding RTP ports (10000 - 20000). I am aware of the security risks, please do not preach.

    I have a problem with port forwarding http port 80 this for i surveillance camera.
    I have all the settings are correct but I can not convert. Opening this port Also no other ports open. Who can help me on the way to this is to get together. I mtu gezte the firewall function in 1400 and put on the standard port 80 http to put. and of course the ip address that is in the same range.
    I do not know what I'm doing wrong because the old linksys just worked. It I hope someone can help me.

  • Not enough port fields in port forwarding for Linksys E4200

    I have always used netgear routers in the past. After a series of issues regarding configurations not working correctly I invested in what appeared to be a semi pro router, the cisco linksys e4200.
    I have a centralized server which I use to access a mass of different services such as mail, dns, VPN, FTP, Kerberos, http and many more. While I am not a massive networking nerd, this server setup is like my garage project. To access these services externally to my LAN as far as I understand I would need to configure port forwarding for each service to my server. Unfortunately the control panel for the linksys E4200 only offers about 15 custom port fields for forwarding, and some documentation I have read shows that with it's basic install my server could be using up to 60 ports at once.
    Is this router just not suitable for this sort of network. If so I will be very disappointed because I have spent a quarter of the price on netgear routers with more control than this.
    If anybody could assist with details and options I would greatly appreciate it

    Wrong forum, use "small business routers".

  • Port forwarding feature in Linksys VoIP adapter

    Hello,
    I tried to use the port forwarding feature (in the Application tab), but could not get successful. I need to telnet to a Cisco router behind my Linksys VoIP Adapter, uses starting port=23, ending port=23 and ip is the Cisco router ip.
    Let me know if I am missing anything. I tried the DMZ feature too, but still the same result.
    When I am trying from outside I get this:
    termserver>telnet 75.156.137.224
    Trying 75.156.137.224 ...
    %Connection refused by remote host
    If I configure the Cisco Router with NAT, I have no problem connecting from outside. I want the Linksys as the gateway, not the Cisco router. Any help would be highly appreciated.

    What is the model number of your Linksys router? Make sure that you have the latest firmware on the device. Also make sure that you forward TCP port 23 for the IP address of the Cisco router coming from the DHCP server of the Linksys router or if you have a static, it has to be on the same subnet as Local IP address of the Linksys router.

  • Linksys E1200 Router not saving Port Forwarding changes

    Hi!
    I am currently attempting to port forward on my Linksys E1200 Router and am not succeeding in saving my settings. I am attempting to open port 25565 though both Single Port Forwarding and Port Range Forwarding, and whenever I click the "save settings" button, I receive a full window message stating that my changes have been saved. Upon clicking this, I return to the previous screen whereupon my changes have been erased and my port has not been forwarded. Can anyone assist me with this? I've searched for hours through forums and tech help websites, but I can't find anyone else with this issue.
    Issue:

    Hi there. You can try another browser or a different computer. If it is the same thing, upgrade the firmware of the router. You can refer to this link on how to http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=0a6881b90224439b92c8d8f19ca42e5d_21511.xml&pid=80&...

  • Port forwarding to different ports on the Linksys WRT54GS.

    As you can guess, I have a Linksys WRT54GS wireless router...one of the original 1.0 versions with speedbooster. Behind this router I have my standard set of machines with dedicated IP's and a set number of IP's for additional devices to acquire IP leases dynamically via DHCP should I bring them home. One of these machines with a dedicated IP is my Debian file server. This machine is headless and without keyboard. It just sits in the corner of a room and hums along. I use SSH to remote into the device to perform maintenance, shutdown, restart, etc.
    My question is this. I would like to know if the WRT54GS can be configured with "unassigned" WAN facing ports (such as 7468) to forward to "assigned" ports such as 22 which is used for SSH. In this way I can leave the default settings for SSH on the Linux machine but have 7468 as the SSH port when connecting from other computers on the Internet. My goal here is to reduce any script kiddies or other malicious code from being able to target the well known port 22.
    In the Games & Applications setup you can find port forwarding and port triggering. It appears that you can only forward by port range. See this link. It gives a start and end to the port range. This appears to only forward a range of ports to the destination IP which is not really what I want to do. Do I need a hacked firmware version to accomplish this?

    you can set the same port number on the port range...
    as for the assigning a specific port for a specific machine, I doubt if it's possible with the a Linksys router...you may need a hacked firmware for this. Or you can DMZ just on the Linux..

  • WRT610N - Need to Set Static IP for Server and Port Forwarding

    Does anyone know how I can assign a static IP for my Home Media Server in the WRT610N router? I need to do this because of the settings I need to set for the server in the Single Port Forwarding.
    Thanks in advance!

  • Port forwarding versus UPNP on Linksys router

    I use ichat3 to videochat with my two sons, both of whom use Trillian on their PCs. Just lately, successful connections have become a rarity - much less than 50% - either failing to start the chat entirely or without audio.
    I have a Linksys WAG54G router (usually connected either wirelessly or via Ethernet to my G4 PowerBook) with UPNP enabled. Yesterday, it seemed that I could connect to the Apple test sites much more reliably if I disabled UPNP. For example, I consistently had no sound from appleu3test01 with UPNP enabled but it worked properly every time I disabled UPNP.
    I am thinking of assigning a static IP address to the PB and changing my router set-up to Port Forwarding in the hope of a better success rate. I've looked at the WAG54G section of the portforward.com website and the suggested iChat settings are:
    Single port page:
    Application     Ext port      Int port     Protocol     IP address
    ichat1     5060     5060     Both     
    ichat2     5190     5190     Both
    ichat3     5220     5220     Both
    ichat4     5222     5222     Both
    ichat5     5678     5678     Both
    Port range page:
    Application     Start     End     TCP/UDP     IP address
    ichat6     16384     16384     Both
    Some questions before I proceed:
    1 Shouldn't the end port for entry ichat6 be 16403?
    2 Are 5220 and 5222 only for Jabber users?
    3 What about other ports such as 5353 and 5297/8 - I don't use Bonjour but I do have other Macs on the same network?
    4 Is there any advantage in specifying TCP or UDP for the ports that only need one?
    5 Any reason to suppose that port forwarding will in fact be better than UPNP?
    Any help will be much appreciated.
    Dave

    Hi Dave,
    Well spotted.
    iChat6 should be 16384 as start and 16403 as end.
    In fact the others would be more secure if:
    ichat1 5060 5060 UDP
    ichat2 5190 5190 Both
    ichat3 5220 5220 TCP
    ichat4 5222 5222 TCP
    ichat5 5678 5678 UDP
    They were pointed at the Protocols that are actually used.
    Re 2 Yes 5220 and 5222 are for Jabber (in Fact Jabber also uses port 5223 for SSL logins All of which are on TCP)
    Re 3 Bonjour is a handy way to do file transfers but someone does have to be there to accept and deliver file (compared to file sharing which does not) If you are not using it you will not need 5297, 5298 or 5353 on the variuos UDP and/or TCP protocols they use
    RE 4 See security above.
    Re 5 If you have multiple computers UPnP is best as Port Forwadring on many domestic devices does not allow the same ports to be forwarded to different IP addresses (Computers)
    For more Security some devices do allow you to set the number of devices away from the UPnP device that it can be "seen" (Descibed as Hops and usually set to a default of 4) I can not find a palce to change this on my WRK54G Wireless router)

  • Port forwarding problems with WRT610N v2 + WAG54GS v1.0

    Background:
    I have a WAG54GS v1.0 (Annex A) which I was using to handle my home network and my ADSL connection. I bought a WRT610N v2 (which I'll refer to as the router) with the intention that it would replace the networking duties of the WAG54GS (which I'll call the modem), which would be relegated to just handling the Internet connection. Both are running their latest firmware.
    I've gotten this configuration to work, but with one problem: I've lost a lot of flexibility in regard to port forwarding. The problem is that the only way I've managed to get the Internet to work is by having the router on 192.168.0.1, and the modem on 192.168.1.1. If I try and have both on 192.168.0.x or 192.168.1.x then connecting to the Internet no longer works under any configuration of options I've tried.
    What this means is that when I go to setup port forwarding in the modem, I can only forwards to clients on 192.168.1.x, but the router can only forward to 192.168.0.x. The only things I can get to work are situations where port range triggering can be applied, so only when a connection is made on the relevant port to an external IP, and then that external IP also communicates back on that port. As you may guess this doesn't nearly cover all cases.
    Question:
    Should it be be possible to have both router and modem on either 192.168.0.x or 192.168.1.x, which would allow port forwarding to work as expected. That should have in theory been possible with the modem's bridge mode except that it's then impossible to configure the PPPoA settings necessary to connect to my ISP.
    Or am I going to have to rethink the network layout (i.e. buy a dedicated ADSL modem and fully retire my WAG54GS?)
    Solved!
    Go to Solution.

    Actually in the end what I figured out was that as far as my WRT610N was concerned my WAG54GS was my ISP, and that was all it needed to know about the Internet connection. So I set it to connect to the WAG54GS with a static IP, stuck that IP into the WAG54GS's DMZ, and left the WRT610N to handle port forwarding as all devices that connect will do so through that. (Yes, I've disabled the wireless features of the WAG54GS)
    I'm reasonably sure I tried the combination of settings you've suggested (including moving the WAG54GS off the Internet port of the WRT610N, which I would have wanted to avoid anyway as I have four permanently connected devices anyway) and found it still wouldn't work. And I wasn't trying to set both to 192.168.1.1 at any point, my self-obscured point was that changing only the last block of the IP address failed to work for accessing the Internet.
