Port Forwarding to two computers.

I want to open ports for an application that I use on two different computers. I have been able to forward the port to on (static) ip and everything works fine. But when I use the application on another computer the port is closed. On my previous router I could say port map to 192.168.0.* and all computers would have the port open, and the app would be fine on either computer. The AEBS does nor recognize the *.
When I set up the same port forward to two different ip addresses with the same ports open I get an error that the port mapping already exists. Is there a way just to have the port open for any computer on the network?
How would I allow incoming traffic to a specific port on either computer? Normally the application is only used on one computer at a time.

  • 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.

    You get the following statement:

    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.

  • Port forwarding to multiple computers

    Hello,
    I am port forwarding from my AirPort Express to my tower so that I can connect via sftp. This uses port 22. If I wanted to connect to another one of my macs at home with sftp can I simply give it any port I want and opn that port in the firewall? Or is there a way to port forward on the same port to multiple machines (which seems weird).
    Thanks for your any help.

    You would use a different public port but the same local port on that Mac.
    So your port mapping rule would be:
    Public port: 222 (or whatever)
    IP address: IPAddressOfYourMac
    Private port: 22
    In this example, the device on the Internet would need to use port 222 to access that Mac.

  • Port Forwarding for Two Macs, one Airport Extreme and one Dynalink RTA1320

    I had previously set up PortForwarding for some of my Applications on my iMac with an Ethernet connected Dynalink RTA1320 Modem by assigning myself a Static IP in the iMac`s Network Preferences.
    All had been good, green smilies on Azureus when D/Ling bitorrents, Skype, WoW and Limewire all running fine.
    I`ve now just recently purchased the latest Airport Extreme and 17" MacBook Pro.
    Setting up a Wireless Network for the two Macs to access the internet was a breeze and both computers run fine online simultaneously.
    I manually set the Ports on the MBP Applications: Skype, Azureus and Limewire to match the Ports I`d previously PortForwarded the RTA1320 to.
    However, on the new MBP, Skype, Azureus and Limewire don`t seem to run too well.
    I get yellow smilies on Azureus and a "Port Appears Closed" message on the NAT Test and my Skype Contacts are leaving me messages saying I always appear "off-line".
    The iMac Apps still work flawlessly.
    I`m guessing the problem is something to do with two Macs on a Wireless Network with one Static IP Address or what am I doing wrong?

  • Port forwarding between two servers from Same subnet

     Hi,
    We have a Cisco ASA 5520 Version 8.4(3). There exists a site to site VPN tunnel between us and a client and the client sends us the data to our local host/server 10.x.x.20 on port 52944. So 10.x.x.20 gets data on port 52944. We want to forward this data to a test server 10.x.x.21( same subnet IP) on port 52945. so basically I want to forward traffic from 10.x.x.20:52944 to 10.x.x.21:52945.
    Is this possible. I am a new bee to the networking and still learning. Excuse me if this sounds silly. 
    I know we can add one more ACL in the VPN tunnel and add this test server IP in the ACL. but, then I have to ask the clinet to change their ACL too. I dont want to do this. So I want to wrok around it. Any help or suggestions is much appreciated.
    Thanks in advance :)
    This is my first ticket in the support community.
    cs

    VMs have nothing to do with it, as long as there's network communication between the servers.
    As I said, there must be a service or application listening on that port for it to respond. For example, try this:
    C:\> telnet
    When the telnet prompt opens, type in:
    open mail.messaging.microsoft.com 25
    If it works, you should see this:
    220 CH1EHSMHS035.bigfish.com Microsoft ESMTP MAIL Service ready at Thu, 7 Feb 2013 00:57:33 +0000
    That means that Microsoft's mail servers are LISTENING on port 25 and it responded. And note, telnetting to port 25 is a non-default telnet port, because port 23 is the default telnet port. When you type in a space and then a port number, you're telling
    the telnet client to use that port.
    That is the SAME THING if some sort of application or service is listening on port 8444 on that other server you're trying to telnet to. If there is no app or service listening, it will just time out.
    And no, installing the TELNET service on that sercver will NOT answer to any port other than 23. The telnet service by default, uses TCP 23, unless you specify otherwise.
    So once again, what service or app on that server is supposed to be listening on 8444?

  • BT HomeHub 5 Port forwarding to 2 PCs

    I have two PCs set up with TightVNC server and can access them both perfectly.  One is on <ipaddress>:ort 5900 and the other on <ipaddress>prt 5901.  I have also set up port forwarding so I can access one PC via the internet using no-ip to handle the ddns.  To set this up I selected the application VNC and linked it to the PC.  This works well and remote TightVNC client can log into the TightVNC server on that PC.   The problem is that I have two PCs running TightVNCserver and I need to remotely log into either or both simultaneously but I cannot set up another port forwarding entry as VNC is in use and removed from the list of applications.
    Is there any way to set up port forwarding to two PCs with different port numbers?
    Thanks

    Without getting my HH out of the cupboard to check, is there not an 'other' application that you can assign the port to? Surely the name is just a label it doesn't have to be called VNC.

  • RVS4000; Port Forwards bypass IP ACL; How to filter

    I am using a RVS4000.  I am forwarding several ports to a specific host on the LAN.  Nonetheless, I wish the IP ACL in the firewall to block incoming traffic from the WAN unless the IP ACL allows.  However, it seems that any port which is forwarded happens prior to and bypasses the ACL rules.  How do I block traffic from "bad" addresses when the destination port is in the forwarding table?

    By George, I think I've got it!  (Well, I've narrowed it down anyway.)  So, I've got an RVS4000 with firmware version V2.0.0.3 and I've been trying to do a similar thing:  I have a NAS sitting on my local LAN with a horribly insecure FTP server on it.  I would like my mainframe to send files to that server.  But I don't want the rest of the friggin Internet beating on it.
    So, I set up a Single Port Forward and two ACL rules, as described by tekliu above.  Alas, just like michaelrach above, every address in the Internet was able to get through the firewall on port 21.
    I read all the posts, asked all the experts, swore a lot, wailed and gnashed my teeth.  Then I set up a test and banged away for a while.
    First, I took Tekliu exactly at his word and try adding (#2) a Deny for everybody and (#1) an Allow for the single IP address I want in.  That worked!  The right host can get in and the wrong host can't.  I'm ready to turn out the lights and go home. 
    But I wanted to figure out why my initial attempt (and those of the others who posted here) didn't work and this one did.  After much guessing, I discovered that if you specify an Allow range of x.y.4.2 thru x.y.4.254, it works correctly.
    If you specify an Allow range of x.y.1.1 thru x.(y+1).1.1 it lets everybody through.
    x.y.4.2 thru x.y.128.254 works correctly.
    x.y.4.2 thru x.y.200.254 lets evrybody through.
    It's the binary difference between the start and end address!  I didn't feel like narrowing it down farther.  But to someone who understand this stuff, this has to be a real good clue as to why it's failing.

  • Remote Access POrt Forwarding

    I
    My ISP provided me a Public IP 64.89.5.xx. Thus I don't get a DHCP IP. I want to able to program my Airport Extreme in order to connect remotely to my Mac Mini.
    How to I configure port forwarding?
    Thanks

    Hello dgonzo45. Welcome to the Apple Discussions!
    Overall port forwarding takes two basic steps: 1) Assign a static or dynamic reserved IP address to the host device on the LAN which you want to access from the Internet, and 2) Assign the port(s) to be forwarded, using the AirPort Utility, on the AirPort base station.
    In this case, you want to assign your Mac Mini the static or dynamic reserved IP address. This address will still be a Private IP address as your AirPort Extreme Base Station (AEBS) will be using the static Public IP address provided by your ISP.
    To reserve an Private IP address for your Mac Mini:
    AirPort Utility > Manual Setup > Internet > DHCP > DHCP Reservations
    o Click on the Plus button to add a reservation.
    o Description: <enter a description here>
    o Reserve address by: MAC Address, and then click Continue.
    o MAC Address: <enter your Mac Mini's AirPort ID>
    o IPv4 Address: <enter the IP address that you want to reserve for the Mac Mini>
    o Click Done
    To configure Port Mappings:
    AirPort Utility > Manual Setup > Internet > NAT > Configure Port Mappings...
    o Click on the Plus button to configure the port maps.
    o Service: <either select a pre-defined service or ignore this setting>
    o Public TCP Port(s): <enter the Public TCP port(s) required>
    o Public UDP Port(s): <enter the Public UDP port(s) required>
    o Private IP Address: <enter the DHCP reserved IP address you assigned the Mac Mini earlier>
    o Private TCP Port(s): <enter the Private TCP port(s) required>
    o Private UDP Port(s): <enter the Private UDP port(s) required>

  • Two web servers cant use same port forwarding rule???

    I have two web servers, each configured to respond to http reqests on port 80.  I use NoIP service to map a domain name to my router. I create a port forwarding assignment for Server A by selecting the WebServer rule in the port forwarding rule table.  All is fine.  For Server B, I select the same Webserver rule and the router says there is a conflict.
    I don't understand why.  I think the router has enough information to route a http request for Server B by knowing its MAC address, which is different than Server A MAC address.
    What am I missing here???
    I was able to do this on my previous router with DD-WRT.....
    So it would appear the way to resolve this is to assign a different port address to Server B???
    grrrrrrrrrr I hate this router

    You shouldn't have been able to do that on any router.  You have to change the listening port of server 2, to 8080 or something like that, or make one a secure server and run it over 443
    That is a known issue with port forwarding
    Problem #8:
    Same Port in Multiple Rules
    There are some routers such as Linksys, D-Link and many others that do not do any checks if a port is already in another port forwarding rule. A port can only be forwarded to one Computer/IP at a time. So when there are multiples of the same port number the port forwarding rule will not work.
    Here is an example.
    As you can see port 2350 is in 2 rules. The 1st one points to a different IP than that of the 2nd rule. So the router will honor the 1st rule and the 2nd port forwarding rule to port 2350 fails.
    By removing the 1st rule the 2nd one will now work.

  • HT3546 How do I set up my air port extreme to do port forwarding? Running 10.7.4 I have a IP camera on my local wireless net work that I want to use from my iPhone 4s and other computers.

    How do I set up my air port extreme to do port forwarding? Running 10.7.4 I have a IP camera on my local wireless net work that I want to use from my iPhone 4s and other computers.

    In most cable systems, the router you have will plug into your modem and just work automatically. A NAT (Network Address Translation) router takes your external IP and hands out LAN (Local Area Network) based IPs. All of the devices you are working with right now should handle the change automatically unless you've changed from the default automatic configuration.
    The problem with your wireless end of this is that the iPhone is not yet 802.11n, only 802.11g. Because that router is not dual band, all of your wifi devices will be forced to slow down to 802.11g speeds. This won't matter much for each device that's connecting to the internet, as your bottleneck is still going to be there. Where you will see slowdowns is device to device connections, like transferring data between the devices.

  • EA6400: Port forward two Netgear ReadyNAS FTP servers

    I have a new EA6400 router with the latest May 2014 firmware. I also have two Netgear ReadyNAS network attached storage devices that are set up as FTP servers. With my old Netgear WNDR3700 with DD-WRT firmware (after the last thunderstorm, may she rest in peace), I could easily set up both with port forwarding and access them outside of my LAN by setting up 4321 and 4311 as ports that translate to 21 and 21 to two different addresses on my network. I have them set up the same way in the EA6400, going into Single Port Forwarding and forwarding 4321 to 21 at 192.168.1.144 and 4311 to 21 at 192.168.1.143, but the EA6400 tells me that I can't use the same port (21). Why not? They're going to different addresses. (Oh I wish I could get DD-WRT on this router!) Is there a way to set up two FTPs on a local network and make them accessible through the EA6400 to an address on the internet?
    I have also attempted to disable one of the port forwards and attempted to access the remaining FTP server and have had no success. I have successfully forwarded a port on the EA6400 to my security camera system so I can monitor my home from the internet, so I know the basics of how this is done. I just can't get single port forwarding to work with my NAS FTP servers.
    Any ideas?

    I switched the settings around and now the other ReadyNAS is coming up, but the one that used to come up no longer does. I also tried replacing the 10001 with 2121 on both EA6400 and on that particular ReadyNAS because it seemed to be a little more common a number for an alternate FTP port.
    So now I have access to the one I couldn't access before and the one I could access before I can no longer access. Of course I can switch them back around again, but I'd like both to work.
    Of course one could potentially put the blame on the ReadyNAS as possibly not being able to work FTP off any other protocol than 21 but I have to place blame on the EA6400 router firmware. This worked well under DD-WRT.
    Anyone have any more ideas? I appreciate the help.

  • Trouble with port forwarding, DHCP, VUZE, and downloading speed.

    I am using Vuze to download things. I have a slow download speed and yellow smiley face, indicating a NAT problem. I think I need to implement a port forwarding, but that requires a static IP address. My router and security is set up such that I CANNOT connect to the internet using a manual configuration--DHCP only. However, I always have the same IP address. This is because the wireless router--a Motorola SB900--will only recognize approved computers designated by the IP address.

    you are dealing with two networks. There is a network between your computer and your router. There is a second network between your router and your ISP.
    Port-forwarding is from your router to your computer.

    However, I always have the same IP address. This is because the wireless router--a Motorola SB900--will only recognize approved computers designated by the IP address.
    Can anyone advise on what to do next?
    You need to set Port-forwarding between your computer and your router. You will need a fixed IP address on a your Computer. There is to ways of doing this. You can set up a static IP address on your computer. A hack would be to add 10 or 20 to your IP address that your router gives out. For example if your router gives out 192.168.1.10 you of would add 10 to the ten giving 192.168.1.20. you need to make the addition to the right most number of which in the example is ten.
    The section way is . . . You can have your router a signed a fixed address based on your MAC address. ( Each Internet device has a fixed address that is called the MAC address. This is a different address than your IP address. the MAC address is assigned in the factory. )
    Another hack would be to Port-forward to the number your router assigned at random. If your Computer is the only computer on the router, the number should always be the same. It is a hack because this is not guaranteed.

  • Are "Back to my MAC" and "Port Forwarding" mutually exclusive?

    I have been using APExtreme and Port Forwarding successfully for several weeks now. The PF is to allow access to game players on a PC which acts as a server on the web. All Good.
    One more thing, I have a ISP provided wireless modem/router to talk to the cable and the world. It seems to work either bridged or un-bridged.
    I have disabled the wireless on the ISP's modem/router. (Actually the ISP's device doesn't hold a candle to the APE.)
    Still all good.
    So the firewall is on in the APExtreme and none on the modem router, and I have a port defined for my gamers to get access to my server in the APExtreme.
    I now want to implement Back to my MAC on my MBP and my other Apple devices. I believe these use iCloud for which I have an account and it seems to be working well with my iPhone.
    In Properties, when I select BtmM, iCloud says communications will be slow if I have port forwarding on. Also I will not be able to use the router function in my Modem/router.
    I'd really like to have the modem/router firewall up, and do the port forwarding there, but the BtmM will likely not get through.
    So what does anyone suggest?
    Can I use BtmM and port forwarding without too much degradation?
    Please advise.
    Thanks
    Barry

    To best answer your question on whether the two are "mutually exclusive," let take a look at how Back to My Mac (BTMM) basically works.
    BTMM - General Requirements
    OS X Leopard 10.7.3+
    Active iCloud account. Each Mac & the AirPort router, that will be relying on BTMM, needs to be configured with the same account.
    A publicly reachable IP address for your router.
    A router that supports either NAT-PMP or UPnP. For AirPorts, be sure it is running 7.6.1+ firmware.
    BTMM uses TCP port 5354 and UDP ports 4500 & 5353 for communications.
    BTMM - Basic Communication Flow
    For a computer connected to the Internet via a router, BTMM "asks" the router for its configuration information. For a router, like your AirPort, that uses NAT-PMP, BTMM will ask the router to assign arbitrary public ports. In turn, the router will provide these port assignments (& the router's Public IP address) back to BTMM.
    BTMM then sends this information to the iCloud account. In background iCloud updates a special set of DNS entries to be used by BTMM. These entries are then made available to all BTMM clients using your iCloud account. When a computer, with BTMM enabled, uses your iCloud credentials, it automatically retrieves a list of all other computers/routers that are registered with the same account. All these devices should then appear under the SHARED section of the Finder.
    When attempting to connect to a remote computer (or router), BTMM creates a secure connection to that remote device using the information from the iCloud account.
    Once the connection is established, the devices can then communicate with each other.
    So potentially, unless you are using Port Mapping for any of the ports BTMM uses, they should not conflict.

Maybe you are looking for
