Summary
A: TippingPoint devices inspect all traffic as long as said traffic is NOT encrypted. Once a VPN tunnel has been established, the traffic flowing thru the tunnel is encrypted so while the IPS cannot inspect the traffic it will attempt to do so thus causing additional load on the system

TippingPoint NGFW devices that are terminating IPsec VPN tunnels, can inspect the traffic within the tunnel. As the VPN traffic is decrypted, the content can be inspected by the device preventing any use of vulnerabilities through client-to-site or site-to-site tunnels. As with the IPS/TPS, encrypted traffic passing through the NGFW cannot be inspected.

Note: It is a recommended best practice to utilize inspection bypass rules to bypass encrypted traffic. This is recommended because the IPS/TPS cannot inspect encrypted traffic and attempting to do so can impact performance and cause unnecessary CPU processing load.
