[SR-Users] Kamailio - PfSense Firewall - inbound/outbound rules

Dear All, I am evaluating the kamailio proxy 5.2 server with rtpproxy on an internal network. Everything are ok. Now, I would like to evalute Kamailio proxy from outside (internet) but I have some difficulties to setup my PfSense firewall to enable inbound & outbound rules, network settings and kamailio.cfg. The issues are : Setup correctly Network files : * /etc/hostname  127.0.0.1 localhost ip_private codecsip.mydomain codecsip ip_public codecsip.mydomain codecsip * /etc/hosts file codesip * dns   * /etc/resolv.conf nameserver 8.8.8.8Setup /etc/kamailio/kamailio.cfg :#!define WITH_MYSQL #!define WITH_AUTH #!define WITH_USRLOCDB #!define WITH_NAT #!define WITH_TLS /* uncomment the next line to disable the auto discovery of local aliases based on reverse DNS on IPs (default on) */ #auto_aliases=no /* add local domain aliases */ alias="codecsip.mydomain" #!ifdef WITH_NAT # ----- rtpproxy params ----- # modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722") modparam("rtpproxy", "rtpproxy_sock", "unix:/var/run/rtpproxy/rtpproxy.sock") Setup etc/default/rtpproxy :   CONTROL_SOCK=udp:127.0.0.1:7722 EXTRA_OPTS="-l <IP-address>" Where <IP-address> is the external IP address of your host. Regarding the firewall rules, it will be great to identify which rules I need to create : Inbound and outbound rules and NAT 1:1 ? If anyone have any information it could be great Best regards, Youssef
