I'am pretty sure now that itsn't a routing problem, but a DNS
resolution
problem.
Why some time, the dns server used is the one from the ISP, and some
time the private DNS server ?
here are the infos requested :

HEllo
I have a strange problem on our VPN :
client on XP SP2 up2dated connecting to our W2K3 RAS server
wich is
located in our LAN behind our firewall.
In our LAN (172.16/16), i have different sublans, our DMZ
(192.168.0/24) and others sublans of our wan.
Since few days, i dont understand why the vpn doens't work
like it used
to be :
when the vpn user is connected, sometimes he can acces to the
DMZ,
sometimes not, when i try to ping server wich is located in
the dmz, it
takes the public adress of the server and not the private one
(means
that it uses the public dns of my FAI and not the private
one). When i
make a nslookup on the vpn client, i can see that the DNS
is our
private one, so it should use the private ip (192.168.0.n)
and not the
public one. For information, we use our DNS domain is
toto.com, the
same one in the public DNS.
when i try to ping a server wich doens't exist in the public
dns, it
works and i can acces to the DMZ.
The strange thing is that i didn't modify our
configuration and
yesterday it worked, today not. yesterday when i ping the
server in the
dmz which exist in the public dns too, it worked and the ip
returned
was a 192.168.0.n
Thks for your idea,
Fadoul
