1 Hi,
2 I think I have a routing problem with network
3 shown below (hope my ascii art survives)
4
5 >From PC2, I cannot ping 192.168.1.1 and no internet.
6 Also cannot ping ISP's DNS servers. But there is full
7 connectivity between PC1 and PC2.

9 At PC2,
10 # traceroute 192.168.1.1
11 traceroute to 192.168.1.1 (192.168.1.1), 30 hops max, 40 byte packets
12 1 * * *
13 2 * * *
14
15 I reached upto this point by following up the
16 gentoo howtos, but now stuck. Any pointers ?
