I was curious if you were able to get Web Admin to work in listen servers. I have got it to work on previous regular servers. I tried using the IP used for step 13, and also tried my local IP.

This is really, cool. I'm glad to know I'll no longer need a server copy of KF2 considering it's coming up on nearly 100gb

Try now, Steam was screwing up the link

I got an Error 400 when opening the Dropbox link. Waited for some hours and still got that on the link.

I updated the link to the xdelta patch, try it again and see if the same checksum happens. If it does then you are either pointing it to the wrong exe, or you have the wrong version of KF2 installed

I followed the steps, however it doesn't work when I applied the patch, it shows:
"An error has occurred: xdelta3: target window checksum mismatch: XD3_INVALID_INPUT"

Ah I see that was gunna be my second suggestion, you're welcome.

I wish it wasn't needed but UE3 doesn't support UPNP

Hey I got It working

I was missing an extra step for port forwarding. I had never done Port forwarding honestly so now I know. Also muy ISP doesnt like me changing configs on their router and that has given me problema before so there's that.

Thanks friend! Good dragon

Hmm okay so, here is what you'll need to do. Start the listen server and then have you friend do open <IP> the IP will be the one you placed in mutate SetIP

If I invite him while inside he gets the short loading screen I mentioned before, and If I create a party and then initiate the server, it appears as if I left the party (I enter alone to the server and he stays behind)
