Port Forwarding Through A Three Router Y Setup

Dec 25, 2011

I'm finally jumping in over Christmas break to set up a Y network with three routers. I run a side business repairing and cleaning viruses/malware from PCs and would like the business subnet not to be able to mix with (and possibly infect) the "home" subnet.Before I knew what I was doing, I set up a simple two router "chained" network by hanging an old SMC router off my main Airport Extreme router, but I've since learned that's not ideal, since the "work" network machines can see everything on the "home" network. So, here's what I want to do. I want to put the new third router right after my cable modem (ISP). I want to keep my Airport Extreme and all devices attaching to it (home subnet) off one LAN port of this new router and my old SMC router off another LAN port of the new router (the test subnet). Currently, the IPs are: [code]My concern in setting up a "Y" configuration is that I have some wireless IP webcams on the Airport Extreme that are using port forwarding (both UDP and HTTP) so I can view them from wherever I am on the Internet, not just from within my home network.

What's the best way to make sure the port forwarding from devices on the Airport Extreme subnet works through the "new" router and out through to the Internet? Do I have to open the same ports on the new router? If so, does anyone have an example using the addresses above? Should I just put the Airport Extreme in the DMZ of the new router (so everything is just passed through - or will that allow my test subnet to see the home subnet? Some other way?

Linksys Wireless Router :: WRT54G - Port Forwarding Setup

Feb 12, 2012

I'm trying to set up my WRT54G wireless router so.i can port forward the relevant ports for my programs. I understand that you have to set up a static ip address before you can do a port forward which makes sense as you do not want to keep changing the ip address for the forwarding settings every time your network refreshes. But I cant seem to have it set up. And is there a rule that the static ip that you set should not be within the dhcp range?After setting up the static ip and setting up the port forward settings how do I test if the port is being forwarded correctly?

Cisco Switching/Routing :: Setup Port Forwarding On 800 Series Router?

Jan 14, 2013

I just setup my homelab today, after having Cat5e installed so I can run my servers and network equiptment over wired network as well as setting up a wireless system.  I got everything setup and its going great I can access everything from my office now including a E4200 Linksys router that I setup to do RiP (was only choice pretty much, or NAT), and my 891 Cisco Router which is my internet connection.
 
I use to have the linksys setup to do port forwarding but now I need to figure out how to do it on the cisco 891 router via command line.
 
Below is my current configuration.  I need to be able to access my server which is behind my router by Remote Desktop.  I also have a web server, and the kids also play minecraft, and have a server setup so I need to be able to forward their port as well.
 
[URL]
 
Ths is from the link above, would I just do like that but then put in my IPs and is that my Private IP I use this or my public facing.   Also he has "interface Dialer1 6881" again after the port in the second and third row.  I dont really understand what they have there.  I understand basic access list and such though I am extremely rusty. 

!
ip nat inside source list 102 interface Dialer1 overload
ip nat inside source static tcp 10.0.0.2 6881 interface Dialer1 6881

Port Forwarding Setup - Remote Directly Into One Of Servers?

Jan 19, 2012

I have a small network in my garage, it's basically made up of a bunch of test servers. Those and a win xp machine are all hooked up to a switch, and the win xp machine also has a wireless usb stick that is connected to my wireless router, and is being used to share internet to the rest of the machines. The test servers along with the NIC card on my win xp machine sit on a different subnet, however.When I remote into the win xp machine from my house, i can run a second remote desktop in the first session, into any of my servers. I want to do work on them, but its very laggy.

Is there a way I can setup a port either on the win xp machine or my wireless router so that i can remote directly into one of the servers? so if the win xp machine has a wireless ip address of 192.16.13.102, and one of the servers on the 2nd subnet has an internal ip of 192.2.2.4, can i have it so i can make, for instance, 192.16.13.102:6333 forward to 192.2.2.4? If not, is there any other way i can directly remote into one of the servers, by passing the first remote desktop into win xp? What settings would have to be the same across the line?

Cisco WAN :: 2910 - Port Forwarding In Dual Setup?

Jan 10, 2013

I have Cisco 2910 router that have 3 interfaces:

g0/0 - LAN
g0/1 - WAN1
g0/2 - WAN2
 
I would like to configure port forwarding in such way that connections to both WAN interface on identical ports will be redirected to a single host in a private network. When I issue command: ip nat inside source static tcp 10.10.10.X 8080 interface g0/1 8080 everything is fine, until I add the second command: ip nat inside source static tcp 10.10.10.X 8080 interface g0/2 8080
 
After that, the first statement is just replaced by the second one, not added to configuration.

Home Network :: Advanced Home Network Setup (3 Subnets) And Port Forwarding?

Feb 24, 2013

I have a Time Warner Cable business class service with no static IP, with a wireless modem which is plugged to a CAT5 distribution panel. On the jacks (2 other rooms on the house) I have a Linksys E3000 and a Linksys Valet router for signal boost and gadgets usage (TV, cameras, etc).The main router (TWC) has it's own external IP which TWC assigns to me and internally distributes via DHCP the range 192.168.0.x. With that said:

- The E3000 has a 192.168.0.6 IP -- this is fixed setup on the TWC router (ubee brand) by MAC address
- The Valet has a 192.168.0.7 IP -- this is fixed setup on the TWC router (ubee brand) by MAC address
- The main router has the 192.168.0.1 as the gateway and web-interface

Whenever I connect something to the E3000, it is distributing the 192.168.1.x range and the valet 192.168.2.x range.That works perfectly for my home based business until I decided to use more stuff on the network such as a IP printer, IP cameras, etc.

- The IP cameras are connected to the E3000 due to signal strength and I have manually assigned them the 192.168.1.15 and 192.168.1.16 IPs and ports 9001 and 9002.

- The printer is connected to the E3000 and I have manually assigned the IP 192.168.1.30.

Issue 1: Port forwarding On the main router (TWC - UBEE) I have tried to setup a port forwarding by informing the Local IP as 192.168.0.6 (E3000 IP), Internal Port 0, Public Interface IP (0.0.0.0), Ext Start Port 9001, Ext End Port 9001, Protocol - Both, Enabled Yes. On the E3000 I did the same config (screen shot attached e3000.png).This is not working properly. I can't get into the camera.

Issue 2: Printer/ The printer is only accessible if I connect to the E3000 (because it is on the 192.168.1.x network)

Issue 3: How to configure all the devices on the same subnet? If I want everyone to be on the 192.168.0.x network, how to configure properly the E3000 and the Valet? I have tried to force them into the same network but it would not work properly. It would not get an IP from the UBEE router (main).

Netgear Router Not Port Forwarding

Mar 27, 2011

Trying to connect to a computer on a client's network. He has a Netgear WGR614v9 router. I talked him through opening port 23 to 192.168.1.200. I have done this many times on other routers and it should have been simple but could not connect. Had him enable ping response so I could ping his router to verify the connection and ping was good. Tried my port scanner and only port 21 is open. Had client verify the port forwarding data and it is correct. Does he need to restart the router to enable port forwarding?

Port Forwarding With A Belkin Router?

Jun 7, 2012

Recently Brighthouse figured out that I was using the wireless router they gave me for actual wireless, and decided to shut it off and tell me I need to pay $100 to use wi-fi on the router. So instead, I went out and bought myself my own belkin wireless router, and plugged it into my old one. Now, I don't know if my old router was indeed a router or a modem. The cable from the wall goes into the older router (let's call that NETGEAR) and from there, an ethernet cable goes into the belkin one (we'll call that BELKIN). Before, when I was using the Wi-Fi on the NETGEAR, port forwarding worked fine, except for having to re-forward ports after my dynamic ip changed. Now, because of the BELKIN router, I can't forward anything? I went into the router management at 192.168.2.1 (for the Belkin), went to Virtual servers forwarded the port 25565 No one can connect to my Minecraft server, only when I plug my computer into my NETGEAR with ethernet (hardwire).

Cisco WAN :: Port Forwarding On 800 Router?

Aug 17, 2011

We have the following port forwards set up on a Cisco 800s router. All internal IP addresses are NATd out to the IP on fa4 which is the external interface.  Traffic recieved on fa4 is forwarded to different servers depending on the type of traffic recieved.
 
We can browse the internal websites from the internet fine, but there is one internal server 192.168.1.7 that uses a db server (192.168.1.5).. it accesses it on its external IP (fa4) on port 1433  but for some reason the connection does not work.. could this be because the source and destination IP addresses are the same IP address?
 
ip nat inside source list 1 interface FastEthernet4 overload
ip nat inside source static tcp 192.168.1.7 21 interface FastEthernet4 21
ip nat inside source static tcp 192.168.1.7 80 interface FastEthernet4 80
ip nat inside source static tcp 192.168.1.7 443 interface FastEthernet4 443

Port Forwarding With Verizon DSL And Linksys Router

Mar 24, 2011

I use Bit Torrent to trade Grateful Dead concert recordings (all legit trading). I have Verizon DSL, a Westell 6100G Modem and a Linksys WRT 160N V2 Router. The Modem is located at 192.168.1.1 and the Router at 192.168.2.1. In the router setup page I have properly forwarded and triggered my ports. However, when I visit my torrent site, it tells me that I am firewalled or "NAT". I used to have the Linksys WRT54G Router and it was configured to PPPoE and everything worked fine. One day I did a firmware upgrade on the router and it would no longer connect to the internet. I switched ti to Automatic Configuration - DHCP and it connected, but performance was slow and this NAT issue began. I eventually got the new router and I have the same problem. If I set it to PPPoE, put in he username and password, I lose my internet connection. If set to Automatic Config - DHCP it works, but, again, "NAT".

Verizon told me that this newer modem self configures itself as PPPoE and there is no need to set the router to PPPoE but I can't seem to get these ports forwarded or get around this NAT issue. It is causing a significant loss of performance and while torrenting I can not connect to others, meaning I can not share what I have downloaded (the torrent client won;t upload). I have been screwing with this for months and have spent endless hours on the phone with Verizon - Linksys says my router is out of warranty so they want $39.95/month for tech support.I have been working with the tech support team on my torrent website and they can't get it figured out either.

F5D8235uk4 - Can't Set The Port Forwarding Ip Address On Belkin Router

Jun 28, 2011

I've just changed my router to a Belkin N+ Wireless Router (F5D8235uk4) My home network is on the 10.0.0.0 ip address range.

I changed the routers IP address to 10.0.0.2 (same as my last one) and the subnet is set to 255.0.0.0

My problem is that whilst my PC's are in the 10.0.0.10 to 10.0.0.20 range my NAS ip is 10.10.10.10 and when I go into the port forwarding (virtual servers) settings on the router it only let's me set the last octet with the first three octets set to 10.0.0. and these can't be changed so I can't port forward to my nas.

Surely the virtual servers should be able to forward to any PC in the subnet, not just those in a 255.255.255.0 subnet? I don't want to change my nas IP address even though that would fix this issue.

Linksys WRT54GS Router - Port Forwarding Not Working?

Jul 18, 2012

I am trying to run a server for minecraft, which some of you may know primarily uses Port 25565. I have tried everything that I've seen suggested. I have a Linksys WRT54GS router that I have my 2 xboxes, playstation 3, pc, and wii connected to. Now, I don't use any of these components at the same time. I had an issue with my xbox and the game "Black Ops", where my NAT type was strict, but a microsoft support technician walked me through port forwarding for the xbox, and it worked. My NAT type was displayed as "open" now. This is not the case with Port 25565 however, as even though I've port forwarded 25565 to my static IP i set up for my PC (which is my server PC), Port checking sites such as "Yougetsignal" and a couple of others are still showing no connection for the current external IP and Port 25565.

I went through ipconfig in windows "cmd" and made sure I had all the ip's and subnets and dns' and whatnot correctly entered in my routers configuration page. I went into Windows firewall and put new rules for port 25565 into incoming rules. None of this seems to work. I even shut off the firewall completely (temporarily, mind you), just to eliminate that possibility, to no avail. Still getting negative responses from these sites. I am able to log into my server myself, using "localhost" as the address, but none of my minecraft buddies can get on my server. I've also tried to use Hamachi to set up a server, which doesn't need ports to be forwarded, but although they can join my hamachi network, they can't join the server. Obviously there is more of a problem than just not being able to open ports, and I am at a loss.

Also, I am aware that my external IP, given by my ISP, will change with every disconnect and reconnect of my signal. I got my current IP address during this time and gave that to my buddies so they could join the non-hamachi network. For the Hamachi server I edited my Hamachi network IP into my server software's properties file, where as it would be left blank for my non-hamachi server.

Linksys Wireless Router :: WRT610N - Way To Set Up Port Forwarding

Jun 26, 2012

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 [URL]... 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.

D-Link DIR-655 :: None Of Port Forwarding Settings Are Working At All On Router

Nov 30, 2012

None of the port forwarding settings are working at all on my router. I have just a couple very simple settings. One of them is just an IP camera. I input the name, the TCP port, the computer (IP address) and that's it. This works just fine with my other Netgear router, but with this router, NADA. The router has the latest version of the firmware applied. Just applied it. Hardware version B. Firmware version: 2.10NA. If so, then I really need my money back since it is a main function of a router and it should work. Can't return it now, since I bought it several months ago. Never knew port forwarding didn't work because I never needed it until now.

Linksys Wireless Router :: EA2700 - NAT And Port Forwarding?

Feb 6, 2013

My first issue with this device is when I try to untick NAT to disable it I lose my internet connection. This also disables access to router's address 192.168.1.1 forcing me to reset the device and set it up all over again. Why is this happening? I tried this at least five times with the same result. Second question I have is if the DHCP reservation is the right option if I want to forward ports for certain applications like Vuze? When the DHCP reservation window opens I see all my wireless devices in the list (laptop, phone) but not the main computer which is connected through ethernet port. But that is yet another problem.
 
I've got a cable modem, connection is set to Automatic DHCP and I all want is to disable all firewalls, NAT and other unnecessary protection that's slowing my internet speed, set up MAC address filtering, port forwarding and close this terrible software so I never have to see it or think about it ever again.
