Source based routing, some TCP packets not SNAT-ed
...p route flush cache
So the default routing table has default route set to GW1 and the table
LAN2 has default gw set to GW2.
I am marking packets in iptables.
iptables -t mangle -A PREROUTING -s $IP1_IN_LAN2
-d ! 10.0.0.0/255.0.0.0 -j MARK --set-mark 0x1
iptables -t mangle -A PREROUTING -s $IP2_IN_LAN2
-d ! 10.0.0.0/255.0.0.0 -j MARK --set-mark 0x1
The last thing in my firewall is:
iptables -t nat -A POSTROUTING -o eth4 -j SNAT
--to-source $Public_IP
The configuration is quite simple, but now straight to the problem:
When I run tethereal I see packets with the correct IP address, but
