pfsense - kamailio - firewall rules to enable SIP & RTP WAN to LAN & LAN to WAN
I am fiuguring out of an issue that I am not able to resolve myself.
I hope the community could help me for that even I googled and found some articles explaining how to enable SIP & RTP rules for the pfsense firewall.
Here my setup is :
Kamailio proxy server (private network)
two audio codec (public ip address)
two audio codec (private network)
pfsense rules for NAT OPTION B : [https://www.outsideopen.com/pfsense-asterisk/](link url)
When calling my two codec from private network. No issue, everything are well.
The codec from public & private network are connected to Kamailio
When I am trying to enable a SIP connection with one of my two codec (public ip address) with one codec from the private network, I can enable SIP but no audio.
If anybody could show me the good way to fi my issue will be great ;-)
I have seen there is a package for sip proxy but not clear if this is what I need.
I don't need asterisk SIP server or other in my private network, I need just to have kamailio as proxy to interconnect private and public audio codecs together.
Thanks in advance if anybody had the same experience of me.
