I use mpd-netgraph to establish a PPTP session to my ADSL provider. When the session is available, ng0 has the public IP address associated with it. ifconfig ng0 shows: public IP -> some IP All the traffic on the public IP address needs to be forwarded without translation to an another ethernet port which has a hardware VPN router that responds to the public IP address. In both directions there should be no translation. I don't think proxy arp will work here. I was hoping to use a set ng hook mpd-netgraph command to link it to another ethernet port.

I have looked at examples, but > they don't work because ng0 is not of type ether. I don't understand.. how do you expect to bridge a point-to-point interface? Why not just have mpd assign the remote side an IP address on the Ethernet netrange using proxy ARP? Eg. "set iface enable proxy-arp"... -Archie __________________________________________________________________________ Archie Cobbs * Packet Design * http://www.packetdesign.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
