Cannot access non-http traffic via full VPN but telnet works

As the application doesn’t work but telnet works the problem is at layer 7. Looked into the configuration observed a traffic policy configured on the Netscaler Gateway VIP.

The Traffic policy was configured with expression “true”.

The action was for SSO to HTTP services and expressions were used.

Herein lies the problem, where the policy with expression true will hit for all traffic, but the action being HTTP specific will fail to execute for non-HTTP traffic, due to this the traffic gets dropped and never forwarded to the back-end.

Telnet to the affected non-HTTP services works because it is just the three-way handshake as there is nothing to be processed.
