Hey all, I'm trying to play Killing Floor with a friend. I forwarded the necessary ports on my router (Aztech DSL1015EN) and my firewall (Comodo). However, my friend still can't seem to join my Listen server. So if there are any networking experts in the house, I'd really appreciate if you guys could help me out.
Here's a screenshot of my router's port forwarding page:

About my router's port forwarding, did I do something wrong with regards to the Server IP Address? Should I be entering something else, since I think 192.168.1.2 is like the internal LAN IP or something like that (I don't know the specific term)?
Ok then there's also port forwarding on Comodo. Any Comodo experts around here? I only recently started using Comodo and am still not used to the interface. Under Firewall > Advanced > Network Security Policy > Application Rules, I have allowed killingfloor.exe to allow all incoming and outgoing ports. Do I need to tinker with the other information in tabs like My Port Sets and Global Rules?

You might want to change the IP from 192.168.1.2 to your ISP assigned IP. It should be found in your router settings page somewhere.

My first step would be completely disable the software firewall for testing, the last thing you want is the software screwing around with the hardware firewall
That looks like port range forwarding rather than single port forwarding, have you got some sort of option to do single ports?
portforward.com has instructions for killing floor on a slightly different model aztech router which looks a bit different but might give you a few pointers

Doing a scan with shieldsup (https://www.grc.com/x/ne.dll?bh0bkyd2) whilst the game is running and trying to access the ports might be a good idea too

Nope. That's the way I have been port forwarding all along. In fact port forwarding has always been somewhat of a hit-or-miss affair for me. Sometimes for certain games, it works; sometimes it just doesnt.
Also! I just realized that my internal IP is not 192.168.1.2, but 192.168.1.3 instead. I have re-forwarded the ports. Hopefully they'll work tonight.
I'm contemplating turning off my Firewall completely, but I'm worried that it may invite intruders. What do you think?
I was told by the settings page - after having accidentally clicked on the Save button without actually filling in the IP part - that the IP in there is my internal IP (a window popped up saying "The internal IP address was not filled in" or somethign like that). So I guess that part is alright after all, thanks

Getting the right IP address might make a BIT of a difference
In theory they can help but practically speaking software firewalls are more trouble than they're worth. To use an analogy, its like having the bathroom door locked to increase house security

So turning off the firewall for a few minutes shouldn't hurt?

Most of the firewalling is done in the network infrastructure provided by your ISP anyway.
I've never used a firewall in all my years on the interblag, and I've never been attacked.
I may have been part of a few botnets and perhaps unknowingly hosted a porn site or three, but honestly, who hasn't !?

Well I knowingly hosted a couple of porn sites, same basic thing

Nevermind.
Erm. When I opened my ports for Wacraft 3, people still couldn't join for a while. But then they were allowed to join about a week later, mysteriously. Nothing had really changed. Maybe it's just being crap?

Respect +1
Ok, so turning off my firewall, are there any other precautions I should take note of? Or I'm just good to try hosting upon turning it off?

we've all been there brother
fist bump

This thread is now officially useless because I just destroyed my router with a firmware-upgrade-gone-bad. Go me! :(

Ooh fun! I'd suggest a better router, a cisco would be good
What a coincidence, fisting was involved...

This thread is now officially useful again :D

Dare I ask for which reason?
