bryguy1010: Hello, I'm new here to GOG.com. I purchased Rebellion from ebay and they provided me with a download. I installed the game on my computer and a friends computer so we could play. Unfortunately, we can't when trying via tcp/ip.

I did view some posts to show what ports to open on the router when hosting. It didn't work. I'm allowed the exception for Rebellion in my firewall and I've even placed the computer I was trying to host on in the DMZ outside my LAN. Still couldn't establish a connection.

Just for trial, I still have an old win xp machine and an old rebellion cdrom game. I ran that and the same with my friend on his own end with a windows 7 modification (had the d3dm.dll) so the versions would match up and I could host. When I tried to use the same win 7 mod that my friend used to connect to my cdrom based xp game...I couldn't host.

In conclusion, I seem to only be able to host from my win xp OS running the rebellion game from the original cd.

I'd rather play on my win 7 computer not having to use an old cdrom. I don't know what to do at this point. I read that some of you play on steam and game ranger? I am ignorant about these sites. I know nothing about them. How does that work? Would playing on those sites circumvent the need for running xp?

Any tips for getting the tcp/ip connection to work would greatly be appreciated and some info in regards to these steam/game ranger options.

Thanks

Samodelkin1: Make sure the following ports are forwarded on your router:
TCP 47624
TCP and UDP 2300-2400
UDP 6073

This is from the official Microsoft website for DirectX. I forwarded both TCP and UDP, just in case.

For instructions on how to port forward your router, go to http://portforward.com/english/routers/port_forwarding/. When clicking on your router brand, be sure to click on close in the upper right hand corner. You DO NOT have to buy their software to use their port forwarding guides.

If you're still unable to host after port forwarding, you can try the following:
1) Enable UPnP on your router. Now try to host via DirectIP, if it still doesn't work, go to step 2.
2) Add a firewall exception to Windows Firewall for Rebexe.exe, EVEN if you don't use Windows Firewall and even if it's disabled.
3) Add a firewall exception for Rebexe.exe to any other firewalls you may have running, whether it's Norton, McAfee, whatever.
4) Repeat steps 2 and 3 with the DirectPlay Helper, typically found at C:\Windows\System32\dpnsvr.exe.

I recommend that both the host and the client do these steps in order to make it work. I can assure you 100% that if you do this correctly, it will work. I've been playing for a long time now, and doing these steps on my Windows 10 system seems to have done the trick. Good luck!

bryguy1010: Hi and thanks for the detailed explanation. I have done most of what you outlined but my opponent has not done so. I will have him try that. Perhaps I can try with you sometime if you'd be willing to and you had some time?

I'll have my buddy give this a try and report back.
Thanks again, very appreciated the help.
