Topic: Error connecting to VPN

[leonardocruz]

hi, all


I have the 7.4 version but in 7.3 version have the problem that can't connect from remote site to my server with VPN, previously i connect fine i think the problem appear with upgrade from 7.2 to 7.3 version, but find and no found anything to solve the problem.
the server is gateway and server have one domain site hosted and use dansguardian to block content.

Please anyone help me to solve this problem,


note: one's days ago with 7.3 version i try solve with data found in a bug, but this don't solve my problem.

What does the server error log say after you try to connect?

[leonardocruz]

i check the log but this is empty, in remote machine try connects user password but no more, and disconnect!

[David Harper]

Look in the server's /var/log/messages immediately after you try to connect to using the VPN.

You may have found a bug. Make sure you have the latest updates, and then if you are still having a problem, file a bug report so the problem can be investigated further.
