IPX routing

Postby wondra » Wed Feb 08, 2006 11:53 am

I know it's a little off-topic, but there are ipx experts around here and those are very hard to find nowadays.
I have the following network scheme:
Win2k---Swithed LAN---Linux server---Coax LAN---Win98
and I want to play DOOM over it. DOOM didn't work on W2k, so I tested it on IPX DirectPlay (Army Men was the first game I stumbled upon)
It works with Linux Ethernet Bridging - the network works okay now.
What I want to know is, why it didn't work with an IPX RIP router?
I've set up both IPX interfaces on Linux, started ipxripd. After a few seconds, all the interfaces were configured, even the Win2k's internal network was in the routing tables. I started a game server, but didn't see it on the other side. I think I tried it both ways.
Anyone any ideas?
Can Win98 make any use of the router? Would it work W2k<>W2k?
Are games somehow marked unroutable?
Where can one find info on how to become an IPX guru nowadays?

Most IPX games from what I remember where broadcast-only, and some set the transport control to 16 right away, so the packets never get routed past the immediate broadcast area. The transport control byte of the IPX packets is incremented at each router and the packet is dropped when this reaches 16. It works like IP's TTL field, except it counts upwards to 16 instead of down to 0.
