[pptp-server] pppd

[bao]

I'm running RH 7.3 with pptp-1.0.1 and ppp-2.4.1-3 (all newest
versions).
When I connect in from a win98 client, it fails when it comes to pppd.

Here is the log:

Using packet sniffer, I see that the linux server sends out lots of LCP
Config Requests, the clients
keeps sending back Encapsulated PPP (GRE). It seems like they can't
communicate with each other.
Please give me any comments b/c without ppp working, i won't get pptp
and dialup to work.

Thanks
