Ah!
It's not asking for the MAC address of the IRC server, it's asking you to specify the MAC address that your RR-NET will use. Setting it to the MAC address of something else on your LAN will definitely cause all sorts of problems, and may well be the cause of your RSTs
That one already solved, but it sure asked for the MAC of the irc-server too, but that one seemed to be solved by a slight adjustment of netmask. (That shouldn't have been a problem, but it was)
My rr-net is using 49:44:45:36:34:00 which is IDE64\0 (default of IDE64)
In my opinion RR, IDE64 or whatever "host interface" should store the MAC to the rr-net.
Now I have some ideas about tcp sequence numbers or something....
Tcpdump on my LAN interface:
16:15:10.591108 IP (tos 0x0, ttl 64, id 13330, offset 0, flags [DF], proto TCP (6), length 40)

...and geolink has totally locked up. Even "mouse" (joystick) is stuck.
One more try, with tcpdump on my WAN interface instead.

...and geos/geolink totally stuck again.
