Hi,

We have a situation and have run out of ideas!
The Situation.

The main Office network is a large network consisting of about 30
servers, Microsoft and a few Netware, with a PIX firewall. Many users
log in from home dial up and VPN.
I am having particular problems with one user trying to VPN in. They
have ADSL at home and a laptop running XP Pro. The VPN client can
connect to the Firewall, yet cannot do anything within the network, ie
ping anything! My laptop which can VPN in from my house ok will not VPN
from the users and theres will VPN from my house. This would indicate a
line issue, yet the user's husband can VPN into his work place with no
problems.

I have spoke to the line providor and they say there are no issues with
additional security on the line. I have also tried a different ADSL
router and completely disabled all Firewalls, software and on the
router, yet cannot make it happen.

Please can anyone help??
Thanks
Karl

Check to see if the IP subnet of the home is the same as at work.

If there is a router, remove it and try connecting directly to the ADSL
modem. If the router is built into the ADSL modem then use a plain
bridge type modem if possible.

IP subnet at home is on DHCP, when VPN client connects to Firewall it
is given a valid work IP address, yet still wont ping anything.

I have tried both sole modem and combined router and makes no
difference.

Any other ideas?

But that does not answer the question he asked. Lets' rephrase it - The
range of IP addresses that the DHCP server hands out - do they conflict
with anything that mey be in teh routing tables back at the main site?

OK.
Then step one in the troubleshooting would be to put the laptop on the
users DSL line without a router - just a dsl modem, load raspppoe on the
laptop, and see if it works then.

If it does (and I bet it does!) you know the issue is with the routers
(the original and the second one you tried)
