Hello everyone. I have a really strange problem and don't know how to solve this. My NTSC version of Quake 3 just refuses to connect to servers - just after getting list of servers and hitting "fight" on one of them process always stops on "Getting arena info". Although browser works fine. Here is additional backstory and what I used in my setup:
Two months ago I got Japanese version of Dreamcast with B type modem. Some time after that I decided to fiddle a little around console and solder VGA mod into it. Then I thought about setting up PC-DC server, so I can play online games on it for free (even ISP's of Vladivostok still do support dial-up, I didn't wanted to pay). Followed Ryochan's tutorial and some of the posts with dial tone generation. I successfully compiled omninet.ko driver for Zyxel 56k duo, did test in browser and everything was fine. Then I opened range of required ports for Quake on router with Openwrt and got this message as I said above. Tried with DMZ stuff, got same as before. Then I was like "Fine, let's check then if it will work with Quake dedicated server on PC". Same thing happened there AGAIN.
I'm almost got mental breakdown after testing different setups/compiling drivers and have really no idea about what I should do. Also thanks for reading this wall of text and sorry for my poor English.
