using different IPs for the signaling and media is not a problem.
I think you should make a trace and compare it with rtp.log.

those are signaling source IP addresses.

Ranges are not supported, but honestly speaking it's not needed. This
option is usually needed only when sip:provider is deployed in private
LAN behind SBC which is relaying the signaling and media from public
internet to the sp:pro.

This is a list, one IP per line
Or put on a single line:
nattest_exception_ips: [10.2.0.10, 10.2.0.12]
