Hello! I am trying to set up a local network consisting out of two laptops under SuSE 8.0 (kernel 2.4.18). The modem on my laptop is not working unde r linux, so I want to use the other computer as a gateway. After dialing in via modem on the other laptop, the routing tables are looking like the following: - computer 1 (141.30.17.252): Kernel IP Routentabelle Ziel Router Genmask Flags Metric Ref Use Iface 141.30.17.252 0.0.0.0 255.255.255.255 UH 0 0 0 eth0 141.30.17.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 0.0.0.0 141.30.17.253 0.0.0.0 UG 0 0 0 eth0 - computer 2 gateway (141.30.17.253): Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 62.104.204.34 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 141.30.17.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 0.0.0.0 62.104.204.34 0.0.0.0 UG 0 0 0 ppp0 From 141.30.17.252 I am able to connect to 141.30.17.253 in our local network, but I do not have access to the outer space. I even cannot ping to 62.104.204.34. On 141.30.17.252 I have a pcmcia network card and the other computer has a internal network card. I am running out of idea s how to get the network working and would appreciate all suggestions. Michael.

Have you a kernel with ip forwarding and have you enabled it ? echo "1" > /proc/sys/net/ipv4/ip_forward And have you same basic masquing rules ? iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE Stef --=20 stef.coene@docum.org "Using Linux as bandwidth manager" http://www.docum.org/ #lartc @ irc.oftc.net
