DIAMETER based on TCP requires a FIXED I/S-CSCFSOURCE PORT in order to make Cx work towards a External HSS

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,

Hi Jan,
This is not supported 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

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.
