cant get thru firewall

July 29, 2011 at 08:01:06
Specs: Windows 7
i have a server at home and i am unable to access it from outside my home network. when i turn the firewall off, it works fine. i have configured an inbound and outbound rule to allow the traffic on the port i am using (8080). I used this port because 80 is cox-blocked. my router is configured to forward properly. the only issue is the firewall. im sure im missing something, just not sure what. i am on win7 and using IIS 7.5 to host the site. any help would be greatly appreciated!

First you said, "when i turn the firewall off, it works fine" and then you said, "my router is configured to forward properly."

If your router were configured correctly, it would work through the firewall. The fact that it works correctly when you remove the firewall from the mix makes me think it's your port forward that's been done incorrectly.

A typical port forward will look as follows:

forward [port #] to [LAN IP Address of target PC]

So lets say your server is sitting on 192.168.1.110 (for example) You would forward port 8080 to 192.168.1.110

Thanks for our reply! that is how the router is configured. i have added inbound and outbound rules in the firewall to allow traffic to :8080. and i'm confused how the firewall is not the suspect. i am using dyndns to redirect from www.mysite.info to http://mysite.info:8080 with cloaking enabled. with the firewall off, all traffic is directed to my server as it should be. so if i didn't have the router config right, i wouldn't see the page remotely correct? or maybe the router needs to match the firewall more accurately? i'm not sure. any help would be appreciated. thanks again!

ok. i went thru and checked everything again. in my Linksys WRT610N, i have configured port range forwarding as follows:

start~~end port protocol To IP address
8080 to 8080 tcp 192.168.1.200(server)

i also have single port forwarding set up:

external port internal port protocol To IP address
8080 8080 TCP 192.168.1.200

when i run the port scan utility from DYNDNS.org, i get one of two results. if the firewall is turned on, it tells me the port is being actively blocked. if the firewall is off, it tells me the port is active and services are running. im doing something wrong, but i can't figure out what.

Well, I have no experience with that exact model of Linksys router.

I have never tried a port scan fron DYNDNS. I always use "Sheild's Up"

If both report that port closed then there's definitely an issue but I can't say what. I think at this point, if you're 100% sure you have the forward created correctly, I would probably call Linksys' support people and ask them what's going on. If anybody can help you resolve this issue, they'll be able to.
