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
