Frustrating VPN Problem

I have a Windows 2003 Server acting as the AD, Exchange Server, FTP
server, web server, and, recently, the VPN server. It's sitting in my
office behind a Linksys router, with the appropriate PPTP ports open
and the VPN settings configured.

When I first set this up yesterday, I could connect to the VPN from
home with my Windows XP Home computer just fine. I was able to browse
the internet, access network resources, and connect to my Exchange
Server with MS Outlook. My partner, on his Mac, could connect, and get
an IP address, but he couldn't get internet or connect Entourage to the
Exchange server. (When I originally tried to set this up some 6 months
ago, the exact same thing happened; I could connect properly but he
couldn't.)

Today, I connected directly to the network while in the office (not
using the VPN), and again everything was still fine. But now, I've
come home and connected to the VPN and it's not working correctly.
Like my partner's Mac, my computer gets an IP address but cannot get on
the internet and cannot connect to the exchange server. The only thing
I can think of is that I did reboot the server while in the office
after installing the latest critical update from MS.

Something I've noticed is that when I run IPconfig /all while connected
to the VPN, the numbers look different than before. I didn't make note
of what they were when the VPN was working, but now my computer gets
the proper IP address from the limited range I've assigned it, but now
the default gateway is the same IP as my connection is assigned, and
the DNS ip is the same as the VPN server (i.e. 192.168.1.64 and
192.168.1.5, respectively). I can't say for sure, but I believe
yesterday when it was working that my gateway IP was the Linksys router
and the DNS was the info from my cable modem. Again, I'm not sure
because I didn't pay attention to it when it was working.

If it helps to know, I don't have the server doing DHCP info; that's
all coming from the router. Again, it worked yesterday so I don't
think that's the problem, but I'll listen to any advice from those who
actually know. Thanks in advance:
