Not unless you have a proxy running for ping on the machine common to the two networks. > You are barking up the wrong tree. How is that? Is ICMP a non-IP packet for it to be routed even if ip_forward is 0? > Normally it is very rare that you set this sysctl. You do it if you are a > firewall or a proxy or if you are running squid. Let us address this specific question. I read what you are saying as - A can ping C via B using static routes on A and ip_forward to 0 in B? A-----------------------------B---------------------C That is wrong. When a packet arrives to a box, if the destination is not local, the packet should be forwarded. This forwarding will happen only if the ip_forward flag is set to 1. OP has also remained silent so far on whether his question was answered.
