IAX2 asterisk firewall rules?

I am trying to get setup a mikrotik router to accepted incoming IAX2 connections UDP 4569 for a DID.

if I remove the router the incoming calls work fine, but when I try and setup the router using standard src rules it doesn’t work. :confused:

Any help with this would be more than welcome

Thank you.

Ah, yes, i have a asterisk server behind my router and this is what i did.

add action=dst-nat chain=dstnat comment=“” disabled=no dst-port=4569
in-interface=wan0 protocol=udp src-address=put-src-asterisk-ip-here to-addresses=
internal-ip-here to-ports=4569
