Hi;

Yes this an old 506 vpn question.

My old 506e running version 6.2(1) failed and was able to find another one. I had the config file so I just dropped it into the other 506e (version 6.3(4)) and was up and running in no time.

However I cannot connect to work via a VPN connection on the firewall, keep getting the Windows error:

"Unable to establish a connection with the VPN server. Unreachable or security parameters are incorrect."


The config is identical except the new one has 3 more aaa-server TACACS+ statements.

AND

the vpdn group inet1 command:


vpdn group inte1 ppp authentication chapnam HAD TO BE changed to vpdn group inte1 ppp authentication chap.....as we use clear unencrypted PAP.


Any ideas, thanks in advance.

Hello,

You'll need to post a scrubbed config and any logs from the pix so that we can understand your network setup.

Ok here are the CLI commands for the PIX 506e ver 6.3, looks like they changed from the older 6.2 ver. Just want to help out those who can benefit from it. Bottom line up and running with the internet and VPN.
Thanks again all.
