I have moved IAX2 over to port 53. The obvious bits were setting bindport=53 in iax.conf, changing the Astlinux firewall to allow UDP 53, and changing my router to forward UDP 53. However Zoiper was a bit of a fiddle. Changing the IAX port to 53 in the Zoiper configuration did not work - the registration failed. A Wireshark trace revealed that this configuration field only affected the source port, the destination port was still using 4569. Adding a ":53" to the "Server Hostname IP" configuration field as well, convinced it to use 53 as the destination port. It now works OK on a local network, now to try it out on the road.
