Really it shouldn't have changed unless you wiped your configs. The reason it can't work with auto-nat is you're not behind a natpmp or upnp router thus you're going to have to set them manually use stun. You can not use stun for rtp-ip or sip-ip, just for ext-sip-ip and ext-rtp-ip once they are set correctly it should work without a problem.

the default setting is "auto-nat".
i changed ext-sip-ip=$${external_sip_ip} and ext-rtp-ip=$${external_rtp_ip}. both of them are set in vars.xml as stun:stun.freeswitch.org. result: same problem
