Port Forwarding and Restricting Incoming Public IP

Installing and Using OpenWrt Network and Wireless Configuration
1

Hi all,

Having an issue trying to find a router that will let me restrict in incoming source IP on a port. Specifically, this is for SIP where a SBC is not in the picture. The port for SIP is to be limited to only the public IP of the SIP providers server.

Now, it appears that with OpenWRT, I can enact such a rule, but was looking to get confirmation that this is possible.

Thanks in advance
