SecureXL does not accelerate VPN traffic
Symptoms
  • Output of 'top' command on Security Gateway shows high CPU load.

  • Output of 'fwaccel stats -s' command on Security Gateway shows that only small portion of the traffic is accelerated.

  • Output of 'fwaccel conns' command on Security Gateway shows that connections that pass through VPN tunnel are "F2F" (Forwarded to Firewall).

  • VPN kernel debug ('fw ctl debug -m VPN + cphwd') shows:

    cphwd_crypt_supported: Accelerator does not support compression;
Cause

"Support IP compression" option is enabled within the VPN Community.

SecureXL does not support IP compression, therefore, the traffic is not accelerated.
