You will have to have a IVL switch for that. (I took me a few days to figure that out on a german dsl provider..) Anyway: to figure out if this is your problem: look at the mac-address of the AC, not the mac-address of the modem itself by tcpdumping both vlans and look at incoming. -- _______________________________________________ Vlan mailing list Vlan@xxxxxxxxxxxxxxx http://www.candelatech.com/mailman/listinfo/vlan
