Vista VPN issues with remote subnets

Hello,

I currenlty have windows 2000 and windows xp clients using PPTP vpn clinets
that connect to a cisco vpn conentrator and a windows 2000 RRAS server. The
vpn servers are on a 10.4.15.x network and the clients gets assigned a
10.4.15.x address from an internal dhcp server. Our preference is to use
split tunneling to limit bandwisth usage so as a practice I leave the 'use
default gateway on remote network' unchecked. I use a DHCP 249 scope option
to assign static routes to the vpn clients that connect via the w2k box. The
static routes point to remote subnets (10.7.0.0 and 165.195.34.0) which are
connected to the 10.4.15.x network via cisco routers and point to point T1
lines. The cisco connectrator assigns the static routes itself when clients
connect. This setup works fine for w2k and xp clients - a remote vpn client
can uses their own internet connection for addresses other then the ones
specified by the dhcp server or cisco connentrator. For example, a remote
client can ping 10.7.12.12 from the cmd prompt via the vpn connetion. The
problem here is vista - it doesn't work right. I can see the static routes in
the routing table (so I know at least it has the info), but when you run a
tracert, it goes out over the internet connection and not the vpn connection.
It should be going over the vpn connection. It doesn't matter if the 'use
default gateway' option is checked or unchecked. It still tries to send the
traffic for the specified static routes out over the internet connection.
Which is really strange, becasue when the 'use default gateway' option in
selected, other internet traffice (except the routes specified) are being
sent over the vpn connection.

Is this some kind of vista bug? Is there a differnet config to setup?

Thanks

Re: Vista VPN issues with remote subnets


i have a vpn subnet issue as well.
the classless route doesn't appear for a client using Vista Home
Premium.
the DHCP hands out opt 249 classless route, but it doesnt appear when a
route print is done. we need the classless to appear and without a
static entry
