I found another thread

SIP Port Forwarding

Hi guys, Wanted to get a definitive direction on this. I notice on my asterisk server heaps of attempts from scammers trying to connect to my server via SIP. On my firewall i have 5060 TCP/UDP forwarded to my server. I checked my firewall logs and i never see an attempt to connect to my server on these ports from my SIP trunk provider so I temporarily removed the rule. this stopped all traffic from scammers and doesn’t appear to affect my trunk connection either which is great. I have mobile us…

Since you’re doing IP Auth it seems you’ll need to port forward and have the external IP set…I’m “registering” to a SIP provider so this setting doesn’t do anything for me [the best I can tell].

Thanks,
