Hi, I am trying to work on this scenario. I have more than four interface signaling IPs lets say interface A, B, C, D. I do have two gateways terminations. Gw X and Gw Y. Gw X sends calls using interface A ip to Gw Y and gateway Y sends calls using interface B to Gw X. Now the problem is. The termination end. Gw Y expects to receive calls with ip of interface B and Gw X expects calls from interface A @dmitry.s both Gateways have different ips whitelisted and are meant to send calls to each other via this switch
Your explanation is not clear.
Gw X sends calls using interface A ip to Gw Y
This is not how it works. GwX may only send calls to yeti. And yeti may route this call to GwY. In this scenario LegB source IP on yeti side configured in termination gw as interface name.
Let me re explain this scanerio. We have two contractors acting both as vendor and customer. Contractor A has our ip A.A whitelisted on their end to send traffic while contractor B has B.B. both Ips interface has been configured on the sems. traffic from customer A with ip A.A is to send traffic to customer B with ip B.B . Do I need to specify the interface name on each gateways?
If you want to use not default interface - you have to specify it in gateway.
