At home I have a cable modem connected to a Windows XP Pro desktop,
shared out via ICS. All very simple so far. I also have a laptop with
Windows 2000 and Checkpoint SecureClient 4.1 installed, for connection
to the office Firewall-1 based VPN.
Now, up until recently
this worked perfectly, the laptop quite happily connected to the office
VPN via ICS on the XP desktop. At the weekend, we had to change some
network configuration at work, leading to the VPN now being accessed
via a different IP address. I reconfigured the SecureClient connection
on the laptop and it works perfectly if I dial out to the internet
directly, but it just doesn't seem to work any more via ICS.
I can
still log in to the VPN successfully, but no traffic after that
seems to work properly. I get no response to even single
pings.
Any ideas?? Now, I'm fairly sure the problem doesn't lie
with the XP machine, as I've re-installed this several times in recent
months, rebuilding it from scratch most of the time and the VPN has
worked throughout. Whatever originally happened to get the VPN working
I believe must have happened on the 2000 laptop, but I just don't know
what it is.
Oh, the laptop also has Windows XP on it, which also
worked with the VPN via ICS, but I don't use that boot O/S for work any
more so SecureClient is not installed now.
As I said at
the start, despite all my current research pointing to
using SecureClient via ICS being impossible, please do not reply
telling me that as I have spent countless hours working using this
configuration so I KNOW IT IS POSSIBLE.
Any help at all
will be most gratefully received.
Mike.
