You will need to add a persistent route statement for the 192.168.10.0/24 
network. route ADD 192.168.10.0 MASK 255.255.255.0  your_gatway_for_192_168.10
   
  You will also need to open ISA server manager and add 
192.168.10.0-192.168.10.255 to the Addresses tab on the Internal interface. 
Finally make sure you have a Firewall Policy to allow traffic from that network 
out the firewall.
  Hope this helps.

  Dear all,

I'm in dire need of some help in a precarious isa-proxy matter.
Allow me to skip to the point;

The network set-up is as follows:
Internet
|
Switch
/ / \
Vpnc Isa Server
|
Lan Switch

The users who authenticate on the vpnc get 192.168.10.0/24 addresses.
The lan users have the 10.1.0.0/24 range.
The isa server has 10.1.0.1 as address on his internal interface and a
public address on his external interface.

Now The p-vpn users need to use the isa server as IE proxy server. (Yes
they have to, company policy does not allow them to use their laptops
with any other proxy server :(, sigh )

Unfortunately I tried everything but to go crazy, to have the isa server
allow this functionality. Now when a pvpn connected client opens a
connection to the isa-server port 8080 he gets an OPEN but whatever we
try the connection closed instantly...

Any idea's are greatly appreciated!

Kind regards,
Bart
