Hello,

I am trying to configure mpd for road warrior w2k clients to connect to,
and I'm running into a few issues, hoping some of you could help out.
I'm not sure if there are other issues that need to be configured
differently besides mpd, like ppp or natd, etc. Or do you need to change
options in the W2K VPN client. Below are my specs, mpd config files, and
error message. Please let me know if you have any suggestions. THANKS!!!

Heres my specs on my testing box:
-----------
FreeBSD 4.9
WAN IP: 1.2.3.4
LAN IP: 10.30.30.1

Recompiled with these options IPFIREWALL, DUMMYNET, BRIDGE, IPSEC:
Pretty basic testing firewall system.

Running ipfw, natd
