[Gllug] routing problems (ip forwarding)

[Liad Bokovsky]

Can you ping 192.168.1.59 from the Zaurus (192.168.2.190) ? I assume you can.

Zaurus	192.168.2.190/24 gw 192.168.2.1

Laptop	192.168.2.1/24
Laptop	192.168.1.59/24	 gw 192.168.1.1

Router	192.168.1.1/24	 gw INTERNET

Did you add a static route to network 192.168.2.0/24 on the Router?
