NetWare 5 Pure IP Login Across Subnets

[Seth Wilson]

We have a Netware 5 server -- IP plus IPX, for our CNE lab work -- whose IP address is 10.0.0.99 and a client -- IP only -- whose address is 198.56.78.13.  The server's subnet connects to E0 on a 2501 -- address 10.0.0.2.  The client's subnet connects to E0/0 on a 3801 -- address 198.56.78.1.  The 2501 and the 3801 are back-to-back and all machines across the board can ping cleanly by name or address. When I move the client to the server's subnet and set its IP to 10.0.0.13, login works just fine.  So login over IP is okay.  But when it's on 198.56.78.13, the client reports it can't find the tree or server.  But as noted, it can ping the server by name or address.  So I conclude that the problem is the broadcast that starts the login process. I set E0/0 on the 3801 to "ip helper-address 10.0.0.99" and still cannot login.   From the packets I captured, it looks like the initial broadcast is NetBIOS Datagram Service, which I thought ought to be forwarded when the IP helper-address is configured.  I am getting a little out of my depth here if you haven't noticed. Can anybody suggest what else I need to do to get the routers to forward this IP Netware login broadcast? Thanks,   ~Seth~
