For interfaces I have
eth0 = internal lan
eth1 = external ip
eth2 = dmz net
I have MASQ setup from internal lan out eth1. When I add an alias to eth1 (for DNATing to an internal server) and setup the DNAT rule, all outbound packets begin to have a source address of the new external alias. This breaks some IP Based access restrictions i have setup among other things (Nevermind that it's just wrong)
I haven't tried rebooting with the stuff added since it's a workday and my users need that to be up, but it would stand to reason that configuring the stuff in order as it does on bootup would fix this. Is there some script I can run to re-init the network / nat / packet filter setup?
