I have a customer with a 1590 - locally managed version R80.20.40.
Their main internet circuit is Ethernet with fixed IP. Dedicated VoIP circuit is PPPoE with dynamic IP.
Automatic Hide NAT for outgoing traffic is OFF as it was interfering with their SIP traffic.
We have source-based static route via PPPoE interface for their VoIP, but in order to NAT it we have to modify the src_adtr object every time the circuit goes down and up again. There appears to be no "This firewall" or even better "This Internet Interface" to create a manual Hide NAT rule with.
Is there a way to do the hide NAT better?
