Hi there,

I've just discovered the power of iptables and it just works well in
my selfbuilt isdn router. However now I also want to route between two
subnets and it just does not work.

I've two network cards in the pc:
eth0 - 192.168.0.1
eth1 - 192.168.1.2

when I try to ping another computer connected to 192.168.0.0/24
everything works fine, however I cannot ping my access-point in
192.168.1.0/24 (which works from a stand-alone computer withought any
problems).

This are my routes:
LKLET021.highwa *               255.255.255.255 UH    0      0        0 ippp0
192.168.1.0     *               255.255.255.0   U     0      0        0 eth1
192.168.0.0     *               255.255.255.0   U     0      0        0 eth0
default         LKLET021.highwa          UG    0      0        0 ippp0
m

Furthermore it would be great if I could use this computer as a
gateway for all computers in 192.168.0.0/24 and 192.168.1.0/24 so that
each computer in this net could reach each other. I tried to configure
iptables a bit, but withought any success :-(

It would be great if anybody could help me, I know those are
newbie-questions, sorry.

Thank you in advance, lg Clemens
