Re: Remote desktop over a VPN



Hi Crane,
Thank you for your information.
In fact, the real problem is that even if the Ipsec VPN tunnel is made
between networks, from SBS LAN client computer I can always ping to any
client in the remote network, but just "sometimes" I can remote desktop
to them: I effectivily could remote desktop several times, but almost
always I get a "Remote desktop desconected" error after a while.
This said, I'll give you the information you asked:
1 - LAN (all Windows XP pro) - SBS 2003 SP1 - Cable modem
----Internet---- Linksys WRV54G - Remote network (all Windows XP pro)
2 - The following is the result oh Ipconfig /all on the SBS server:

Finally, in ISA 2004 for all this to work, I created the VPN Remote
network using Ipsec (the only possibility given by the Linksys router
in the remote network?), and the correspondig network rule and firewall
rule. This seems to work nice, since I can always ping the remote
clients (and the status of the Linksys router says also "connected"

If you have some suggestions, I'll be looking for them.

Thank you again!

Omar
