Thanks, Godfrey but I cannot change the default GW for the SIP servers to point to the LTM private VLAN Self IP.

The irule I've posted before seems to be working partially...

All the requests coming from SIP clients get translated and forwarded to the SIP server. Replies from SIP servers are going over the LTM Automap NAT IP and then get translated and hit the SIP client.

So far so good.

BUT when SIP server has to terminate the call by sending BYE REQUEST that request is being sent to the SIP phone IP instead of to the Automap Private IP. As we are bloking any traffic coming from Internet on port 5060 on our SIP servers the OK reply message never hit the SIP server.

Do you have any idea how I can make SIP server to send REQUEST messages to F5 Automap private IP instead of to the SIP agent directly?

Thank you!
