Ok, I have successfully resolve part of the problem. I am running Linux-Mandrake 7.1 (too many problems updating my Laptop to upgrade my server - but that's another story!). I have the latest Kernel source 2.2.17-21mdk (I couldn't install the -23mdk -unknown dependencies). I originally obtained and installed the pptp-client-1.0.2 software from the rpmfind.net depot. I ran the pptp-client with the ppp software from the Linux-Mandrake 7.1 distribution. This is was caused the error message "Peer is not authorized to use remote address 10.15.1.100". It also produced the error message "Unauthorized Remote IP Address" in the connection log for pppd. I was able to eliminate this error by upgrading to the ppp-2.4.0-3mdk. My final connection problem is the following error message: Nov 10 13:29:12 mail pppd[1042]: pppd 2.4.0 started by root, uid 0 Nov 10 13:29:12 mail pppd[1042]: Using interface ppp0 Nov 10 13:29:12 mail pppd[1042]: Connect: ppp0 <--> /dev/ttya0 Nov 10 13:29:14 mail kernel: ip_demasq_gre(): 198.30.140.7 -> 64.249.148.250 CID=0 no masq table, discarding Nov 10 13:29:15 mail last message repeated 12 times I have the 2.2.17 kernel, included pptp support, and even attempted the GRE support. NONE of this helped. One more thing, the Linux-Mandrake Kernels already appear to have the vpn_masq and pptp Kernel patches. Now what?
