I've added provider marks @ Router1 /providers
#NAME NUM MARK DUP INTFC GW OPTS ispA 1 0x100 - EXT_IF detect track,balance vpnA 2 0x200 - VPN_IF 10.1.1.2 track,fallback @ Router2 /providers #NAME NUM MARK DUP INTFC GW OPTS isbB 1 0x100 - EXT_IF detect track,balance vpnB 2 0x200 - VPN_IF 10.1.1.1 track,fallback So that, IIUC, traffic moving either direction over the vpn link gets a 0x200 mark. If that's correctly done, then can that mark be used to 'tell' SW the routeback path to use IFF the mark is present? _______________________________________________ Shorewall-users mailing list Shorewall-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/shorewall-users
