Connecting to a PIX firewall using cisco VPM client though a Linksys WAG54G with eth firewall enabled
Posted by Phil on December 11th, 2004


I have a Linksys WAG54G wireless ADSL rouer.

I can connect to my companies PIX firewall using the Cisco VPN client if I
disable its internat firewall.
When the Linksys firewall is enabled the VPN fails on the IKE

I have triedd using the gaming options to open up port 500 but it still
doesn't work.

Client trace below with IP address removed.

Cheers,

Philip

On the PIX, ensure that isakmp nat-traversal 20 is set.
That command is supported from 6.3(1) as I recall.
