Unable to bypass Non Compliant HTTP protection over VPN on R82.10

[Ben138019]

Hello, 

We havge sql backups running over a VPN connection over port 8403.  Aftter upgrading to R82.10 these connections started to be blocked due to protection type: Protocol Anomaly HTTP with protection name of: Non Compliant HTTP.  

We added the following exceptions but none of them resolved the issue.  The only way to resolve the issue was to disable Non Compliant HTTP outright from the profile
