Cannot connect to a corporate network with AT&T VPN Client through a Linksys router WRV54G
Posted on 2005-04-16
I have a network for my small business at home. I have a Linksys router WRV54G with three Apple computers working perfectly. My wife works for IBM and she works from home many times. IBM includes in their corporate laptops an AT&T VPN client. When this computer is connected directly to Internet, she can connect to IBM corporate network without problems. When she is behind of my firewall, she can't.
To avoid this problem I gave to the IBM laptop computer a fixed IP address and I have created a DMZ with this host in the firewall. Now it is working, but this computer is not protected.
I have tried many changes in the firewall set up without success. I have open the port 80, 500 and several more and nothing happened. The VPN tunnels are opened in the firewall as well. Everything in the firewall seems to be correct.
I have read that the release of AT&T VPN client that my wife is using is prepared to run behind a NAT/firewall device. I have also seen a file called NCSetup.ini in the VPN client folder with some entries talking about firewalls. Is there any set up to change there?
Thanks in advance for your help,
