virtual server h323 with all ports and protocols does not working

Hello everyone,

 

Well, I tried to configure VS for H323 with all protocols and all port enabled (automap), and is working fine with outbound traffic, but when I tried to call my VS (inbound), I only see "syn" packets coming from internet , Ringing shown but can not answer the call, if push green button the call is not established at all. Thus, UDP traffic does not transfer.

 

Collected logs when i tried to call from INT:

I made some port tests from BigIP (like telnet to the node 172.20.20.90) and all responses are without problems.

 

I opened a support case, but can not help me with this configuration, I am looking for F5 documents on H 323, LITERALLY ... I have not found anything.

 

Please help me about this.

 

Best regards.
