ok, this is the situation.
I need to remotely work on a machine running XP Pro SP2. Remote Desktop is enabled is working fine from the LAN. Whilst doing this I still need to access the local LAN and browse the web using the local gateway.
The PC is connected to a LAN and has a Cisco PIX 506E as the default gateway. This in turn is connected to a broadband modem with fixed IP address. The pix has a public Ip address on teh outside and a privite LAN Address on the inside.
The PC is on the same address space as the PIX inside interface. I have configured the pix to accept both IPSEC and PPTP tunnels, although I'd prefer to use (3DES) IPSEC.
Now, using a remote PC, eg a laptop connected to a dial-up, I connect to the PIX using cisco VPN client 4.0.1 and successfully connect a IPSEC tunnel. I then try to run remote desktop and ... nothing. However I can browse the internet using my local LAN so split-tunnelling seems to be working. btw Windows firewall is off.
OK, so I try to do the same using the PPTP client native to XP. I create the tunnel fine. I connect to remote desktop fine. So I try the same thing on another laptop, and this time the PPTP tunnel does not connect. So it is inconsistent between PCs for no apparent reason?
I'd prefer the fix for the Cisco client, but any help appreciated here.
heres the pix config:
