Change "128.32.43.97" to "10.186.221.x" where "10.186.221.x" is the address of the mpd machine on the private network. This line is setting the IP addresses of the point-to-point link that is the "inside" of the tunnel. What you've got will make the remote machine think that the route to 128.32.43.97 is via the PPTP, ok, so take the packet and wrap it in a GRE packet and send that to 128.32.43.97, ok, so what was the route to 128.32.43.97? Oops.. that is, infinite routing loop. Also, "10.186.221.0/24" looks fishy.. the peer is not going to know what IP it should want so there's no need to allow leeway (ie, 24 vs 32). You should change to a definite address, eg, 10.186.221.123/32. So something like set ipcp ranges 10.186.221.100/32 10.186.221.101/32 should work better. -Archie ___________________________________________________________________________ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
