[pptp-server] MSCHAP

Tue Aug 24 04:42:32 CDT 1999

Well, wouldn't you need for pppd to assign different addresses than what you
normally use.  This is a vpn and as such it is rather customary to assign
the client an ip address off of a internal subnet and proxyarp it.

Windows is rather particular about his routing table/routing behavior using
a vpn when you are assigning something similar to what he is using for his
lan/dial connection.

|Check your pptpd.log. Look for something about unable to set proxy arp..
|This is the most common problem. The readme that comes with poptop talks
