2003 firewall issue

i've looked at documentation, knowledge base and can't find anything to see
if i'm doing something wrong here

environment:
2003 sp1 with 2 network connections-out(connected to internet) in(inside
network)
xp sp2 clients

problem:
firewall service on and is enabled for out connection but NOT for in
connection
xp clients can't connect to server; packet loss on ping
turn off firewall, xp clients can connect to server no problem

i can understand if the firewall was enabled on the in connection, i could
just open whatever ports i need, but it isn't
i've look at article 298804 but it doesn't help any

any ideas??

Since this server has two NICs, I would use RRAS instead of windows firewall.

Don't run Windows Firewall on 2003 DC
Don't run Windows Firewall on ISA server
Don't run Windows Firewall on 2003 RRAS
