I've installed *freeswitch into a local environment* and I perform SIP calls well using the server local IP. This server has connected to ADSL network with a *static public IP* but when I try to call using the public IP instead of the local IP the server receive the call not work... The clients can register well (or I think so). Others process like apache work well. I NAT forwarding in the firewall the next ports: 5060, 5080, 7443. *$ netstat -putan* Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 192.168.230.143:2855 0.0.0.0:* LISTEN 15894/freeswitch tcp 0 0 192.168.230.143:2856 0.0.0.0:* LISTEN 15894/freeswitch tcp 0 0 192.168.230.143:5066 0.0.0.0:* LISTEN 15894/freeswitch tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 1166/nginx -g daemo tcp 0 0 192.168.230.143:7443 0.0.0.0:* LISTEN 15894/freeswitch tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1079/sshd tcp 0 0 192.168.230.143:5080 0.0.0.0:* LISTEN 15894/freeswitch tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 1166/nginx -g daemo tcp 0 0 192.168.230.143:5060 0.0.0.0:* LISTEN 15894/freeswitch tcp 0 0 192.168.230.143:22 192.168.230.167:60298 ESTABLISHED 14816/sshd: ubuntu tcp 0 0 192.168.230.143:22 192.168.230.167:60296 ESTABLISHED 14744/sshd: ubuntu tcp6 0 0 :::80 :::* LISTEN 1166/nginx -g daemo tcp6 0 0 :::8021 :::* LISTEN 15894/freeswitch tcp6 0 0 :::22 :::* LISTEN 1079/sshd tcp6 0 0 ::1:5080 :::* LISTEN 15894/freeswitch tcp6 0 0 :::443 :::* LISTEN 1166/nginx -g daemo tcp6 0 0 ::1:5060 :::* LISTEN 15894/freeswitch udp 0 0 192.168.230.143:5060 0.0.0.0:* 15894/freeswitch udp 0 0 192.168.230.143:5080 0.0.0.0:* 15894/freeswitch udp 0 0 0.0.0.0:68 0.0.0.0:* 1019/dhclient udp6 0 0 ::1:5060 :::* 15894/freeswitch udp6 0 0 ::1:5080 :::* 15894/freeswitch *$ fs_cli -x "sofia status"* Name Type Data State ================================================================================================= external-ipv6 profile sip:mod_sofia@[::1]:5080 RUNNING (0) 192.168.230.143 alias internal ALIASED external profile sip:mod_sofia@192.168.230.143:5080 RUNNING (0) external::example.com gateway sip:joeuser@example.com NOREG internal-ipv6 profile sip:mod_sofia@[::1]:5060 RUNNING (0) internal profile sip:mod_sofia@192.168.230.143:5060 RUNNING (0) ================================================================================================= *$ fs_cli -x "sofia status profile external"* ================================================================================================= Name external Domain Name N/A Auto-NAT false DBName sofia_reg_external Pres Hosts Dialplan XML Context public Challenge Realm auto_to RTP-IP 192.168.230.143 SIP-IP 192.168.230.143 URL sip:mod_sofia@192.168.230.143:5080 BIND-URL sip:mod_sofia@192.168.230.143:5080;transport=udp,tcp HOLD-MUSIC local_stream://moh OUTBOUND-PROXY N/A CODECS IN OPUS,G722,PCMU,PCMA,VP8,H264 CODECS OUT OPUS,G722,PCMU,PCMA,VP8,H264 TEL-EVENT 101 DTMF-MODE rfc2833 CNG 13 SESSION-TO 0 MAX-DIALOG 0 NOMEDIA false LATE-NEG true PROXY-MEDIA false ZRTP-PASSTHRU true AGGRESSIVENAT false CALLS-IN 0 FAILED-CALLS-IN 0 CALLS-OUT 0 FAILED-CALLS-OUT 0 REGISTRATIONS 0 *$ grep -r '"ext-' ** sip_profiles/external.xml: <param name="ext-rtp-ip" value="auto-nat"/> sip_profiles/external.xml: <param name="ext-rtp-ip" value="auto-nat"/> sip_profiles/internal.xml: <param name="ext-rtp-ip" value="auto-nat"/> sip_profiles/internal.xml: <param name="ext-sip-ip" value="auto-nat"/> When I perform a call the freeswitch.log file show: df895d9a-30f2-40b5-97bb-56e222c1c45f 2017-07-18 14:44:51.218939 [NOTICE] switch_channel.c:1104 New Channel sofia/internal/1009@192.168.230.143:5060 [df895d9a-30f2-40b5-97bb-56e222c1c45f] df895d9a-30f2-40b5-97bb-56e222c1c45f 2017-07-18 14:44:51.218939 [DEBUG] switch_core_state_machine.c:584 (sofia/internal/1009@192.168.230.143:5060) Running State Change CS_NEW (Cur 1 Tot 7) df895d9a-30f2-40b5-97bb-56e222c1c45f 2017-07-18 14:44:51.218939 [DEBUG] sofia.c:10067 sofia/internal/1009@192.168.230.143:5060 receiving invite from 88.33.111.22:57076 version: 1.9.0 -493-13f2f2a 64bit 2017-07-18 14:44:51.218939 [DEBUG] sofia.c:10238 IP 88.33.111.22 Rejected by acl "domains".
