Hello, Well ...
The difference between our prod server and the test server was the running (or not) of our iptables script that enable ip forwarding (the server is also a gateway). >From scratch, "source a.b.c.d" works well. After "/sbin/iptables -A POSTROUTING -t nat -o eth0 -j MASQUERADE", source is ignored and the fisrt ip of the routing table is taken. (the new server only have real nic (eth0, eth1, etc), there is no alias anymore) So, new questions ... Is it normal ? Is it bad to have the same server for haproxy and gateway ? Thanks !
