Hi, I use iptables command to mark certain traffic and route it via a vpn tunnel. Configuration: SH1 -- R1 ----------------R2 -- RH1 Openvpn tunnel between R1 & R2. At R1, I use iptables to mark & route certain traffic(ping ICMP packets) via openvpn-tunnel. At R2 I use MASQUERADING when sending traffic to RH1. When I ping from SH1 to RH1, ping requests reach RH1, but ping replies from RH1, received at the tun0 of R1 but not routed to the subnet (to SH1). I have the required routing entry at R1. But when I ping from SH1 to R2, there was no problem. I have provided all the details, config & iptables command used etc ..in the attached pdf file. Pl. have a look at the pdf file and give your comments. Thanks & Rgds Thava __________________________________ Yahoo! Music Unlimited Access over 1 million songs.
