VPN over ICS

[Tony Zabaneh]

Dear all
I have a 6 sites network, the main office has a windows 2003 server with
routing and remote access service, and its accepting connections perfectly
from all the other sites through VPN, all the other 5 sites, has windows XP
with ICS enabled to give other computers each on its network internet
access,

my problem is whenever one of the ICS computers dials the VPN , the other
computers on its network suddenly loses internet and network access to the
server of course, all the sites has windows XP professional, and connected
through DSL with static IP's

waiting your help
regards
Tony

They should be using a VPN enabled Cable/DSL Route, not ICS. The Router, not a PC, will
create the tunnel and the Router will allow all LAN nodes the needed access.

As always, I suggest blocking both TCP and UDP ports 135 ~ 139 and 445 on *any* SOHO Router.

there is a small program that is called PORTTUNNEL
from www.steelbytes.com

that creates tunnels for ICS.
You install it on the ICS server machine with XP and there you define the
ports, and IP addresses of the machines you want to tunnel.

Works great!

The truth is one, you must accept it. Reality is not a point of view, since
if everything was a point a view, then the theory that everything is a point
of view, is just a point a view and not something real.
