TCP/IP + IPX

[Meder Kydyraliev]

Hello,
i am goin to be separating 2 servers from the lan (1 server TCP/IP stuff, 2nd is IPX 
Novell server). If i will put OpenBSd 3.1-STABLE firewall between lan and server i 
will be able to to regular tcp/ip filtering  to my 1st server and what will happen 
with IPX traffic to the Novell? will it be passed or dropped? i won't be able to do 
any IPX filtering right?
thanks in advance,
Meder
