Putty Timeout when AFM VPN is used

Hi,

Did you mean Access Policy Manager (APM) VPN SSL Network Access?

Advanced Firewall Manager (AFM) is the Network Firewall module with dos protection of BIG-IP suite.

If you have administrator access to the server, please check the ClientAliveInterval, TCPKeepAlive and ClientAliveCountMax options in the SSHd configuration file.

Also, try enable TCP Keepalives in Putty Connection options.

Finally, use tcpdump in the BIG-IP system to capture a whole Putty connection and paste the output here to see the details.

Bye.
