Hello To everyone: I've setup a linux box with 3 ethernet cards. One in the 10.0.0.0/8 net in the eth0, the other in the 192.168.10.0/24 in the eth2 and the other is connected to dsl modemwith with eth1. I've setup forwarding with, net.ipv4.ip_forward = 1. A strange phenomenon happens that I don't understantd. When I make an echo request from a host in the net 10.0.0.0 to a host in the 192.168.10.0 the packet arrives to the eth0 interface but it seems that it doesn't traverse the linux because with tcpdump I see no icmp packet in eth2 But when a make an echo request from the 192.168.10.0 to a host in 10.0.0.0 , I receive the echo reply and, inmediatley the echo request originated in 10.0.0.0 receives the echo replies from 192.168.10.0. If would appreciate any idea, Sorry for my poor English. Thanks in advance
