Might I suggest a netgraph bridge, where the tunnel is implemented as a tcp or UDP socket layer (optionally with ipsec). use a netgraph bridge node on each side, and connect them using ksocket nodes which are linked to each other. you might also find that you can use mpd as a good link between them. I've done this in the past but do not have working examples in front of me. > - The Wifi client must be part of LAN X and receive a DHCP address from > a DHCP server (not shown) on LAN X > - On the access point wlan0 and gif0 are bridged together > - On the gateway fxp1 and gif0 are bridged together > - Gif0 on the access point and gif0 on the gateway communicate correctly > when given IP addresses > > Regards, > > Paul Schenkeveld > _______________________________________________ > freebsd-net@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-net > To unsubscribe, send any mail to "freebsd-net-unsubscribe@freebsd.org"
