I don't think the user has to do this manually. At least I can't remeber that I needed to set promisc manually somewhere in the past.

Afterwords, in the openvpn config your could just have the tun/tap interface attached to the already existing (1-port)-bridge. bye, Ralph P.s.: Just a quick one: Question: What name could you also use for a multiport-bridge? Answer: Switch, because a multiport bridge is nothing else then a switch :) _______________________________________________ freewrt-users mailing list [email protected] https://www.freewrt.org/lists/listinfo/freewrt-users
