Port Forwarding is not working on my Linksys e1000
Posted on 2011-10-21
I am trying to setup port forwarding on my Linksys E1000 and a Windows XP computer. I need to have a block of 100 ports available for some software to communicate across the internet. The software will run on a Windows XP machine and there shouldn’t be more than 5 to 10 connections to the computer at any one time. Right now there are only about 3 connections.
I followed the instructions as defined in the E1000 docs. I have a static IP from my cable provider. I have that programmed in the router. This seems to be working fine because I have wired and wireless connections communicating through the router that don’t need specific IPs, so these computers use the default dynamic configuration. I just need the XP computer to have a static IP address.
I went to the applications and games areas and then the port forwarding tab and typed in the following:
Start End Protocol IP Address Enabled
6700 6799 Both 192.168.1.102 Yes
Then I set up the XP computer to point to 192.168.1.102 . The subnet mask was set to 255.255.255.240 – according to the cable guys.
So, I checked the computer setup using “ipconfig /all”. It shows that the address was set, but the DHCP has not. It said No. I bring this up because on my wireless laptop the DHCP is set to yes for its configuration. But this configuration is automatic. The IP is not specified, so it is getting its IP from the router.
On the XP computer, after I setup everything, I get no internet access at all. I tried to ping yahoo.com – no luck. On my laptop, I did ping yahoo.com successfully.
What am I doing wrong? I think it is either the DHCP or a firewall issue. However, I did disable the firewall on the XP computer – still no luck.
Desperate. Please advise.
