I have a ASA 5525-X appliance. I have 5 VoIP Cards that need to be programmed with external IPS (38.84.x.x) so i cant program them with a internal and then Nat they all need to have public facing IP address programmed on them. They sit behind my firewall but when i try to place a call to them port 5060 gets blocked by the implicit rule . What the rule shows is the the external IPS (38.84.x.x) as the source Ip with the outgoing interface and then it shows the SIP providers IP (38.87.x.x) as the destination. I created a access rule and it is still being blocked and my calls are failing. How do i get around this issue
