Hi Jan,

This is not supported

I wrote in another recent message as well, it is not guaranteed you can set the local port for tcp connections, due to the design of tcp protocol. One can attempt, but restricting on that is not a sustainable policy, at least for firewall rules.

Cheers,
Daniel


but I have a question, what happens if you want to connect to multiple HSSs? Say for load balancing or failover (assuming no DRA)? Fixing the source port seems pretty restrictive to me ;)

Cheers
Jason

Hi experts,


from the current trace we can see that the I/S-CSCF always changes SOURCE port when contacting our eternal HSS.

In order to make the Cx work HSS expects the Source port to be fixed on the TCP layer and in our I/S-CSCF configuration we did not find any setting for SOURCE Port.


Can somebody help us please ;-) ?


We appreciate your support,


Br,
Jan
