Hi, i try to get the following work for days now and realy need some hints. My situaution: I have 2 independent links to the internet. I would like to get connections from the internet to an internal host work, regardless to which of my external IP. I tried it by marking packets coming in EXTIF1 and set up a own routing table for marked packets. But it seems the routing does not work bacause teh packets disappear between PREROUTING and FORWARD. Please help! Some config lines: # ip rule ls 0: from all lookup local 32765: from all fwmark 1 lookup post.out 32766: from all lookup main 32767: from all lookup default # ip ro sh tab post.out 192.168.100.0/24 dev eth0 scope link src 192.168.100.3 default via EXTIP2 dev eth2 # iptables -L -nv -t mangle 1624 113K MARK all -- eth2 * 0.0.0.0/0 0.0.0.0/0 MARK set 0x1 Thanks for any Tips, Documentation links ...
