Re: Cannot access LAN computers when connecting from externally via VPN.

Hi Guys,

Firstly, thank you all very much for your help.

Changing the IP range for VPN DHCP has indeed solved the problem, and
I can now access the internal systems.

I'm still confused by it all though. I have a virtually identical
setup on a different system, running exactly the same software -
SBS2000, ISA Server 2000, etc. The only difference is that the
external IP is 192.168.4.2/24 (router is 192.168.4.1) and the internal
IP is the conventional 10.0.0.2/24. On this system the VPN DHCP range
is also 172.16.x.x/24, and I can successfully access all the internal
addresses! So to summarise:

External IP 192.168.0.2/24
Internal IP 192.168.1.43/24
VPN DHCP 172.16.2.1/24

does not work, but

External IP 192.168.4.2/24
Internal IP 10.0.0.2/24
VPN DHCP 172.16.2.1/24

does work. Very strange - or am I missing something?

If somebody can give me an explanation then that would be great, but
as the existing problem is now solved I'll try to not lose sleep over
it....
