Hi, I have a pptpd running on a router (ubuntu 8.04) with two WAN connections and does some traffic balancing on these connections (configured with ebox-platform btw) The pptp is configured to listen on the first (eth0) WAN connection, but sometimes the GRE traffic is going via the second WAN (eth1) connection, which results in a 619 error in the microsoft pptp client after a while (makes sense I guess). I tried adding a rule in my mangle table, which seems to work for tcp port 1723 but not for GRE. What am I doing wrong? The correspondig rules are: -A PREROUTING -m mark --mark 0x0/0xff -m mac --mac-source 00:19:CB:3E:2A:0F -j MARK --set-mark 0x1 -A PREROUTING -m mark --mark 0x0/0xff -m mac --mac-source 00:1B:54:CB:7E:05 -j MARK --set-mark 0x2 -A PREROUTING -p tcp -m tcp --sport 1723 -m mark --mark 0x0/0xff -j MARK --set-mark 0x1 -A PREROUTING -p gre -m mark --mark 0x0/0xff -j MARK --set-mark 0x1 Thanks for your help!
