      I'm focusing on retraining brain to pfSense way (which I don't doubt is the way everyone does stuff) but there's some resistance to source vs destination in lan v wan.

      As suggested in many SIP forums I've changed

      Firewall: NAT: Outbound
      ticked: Manual Outbound NAT rule generation

      Auto created rule for LAN to WAN
      static port: NO

      Because I've been suffering VoIP quality issues for some time I added some overkill

      Firewall: NAT: Port Forward

      wan
      proto: tcp/udp
      src addr:  my_voip
      src port:  any
      dest addr:  wan address
      dest ports: my_sip
      nat ip: my_obi
      nat ports: my_sip

      in the associated firewall rule I added it to Ackqueue/Queue:  none/qVoip

      The question is have I lined up the src & dest appropriately?

      and what associated dest/src lan NAT should I add to this end?

      it's tcp/udp because some of my providers can 'SIP TCP' (sip2sip & anveo).

      alias:hosts
      my_voip=
      a list of all my sip/voip providers including their proxies – any hosts used by lan devices and respective DNS SRV RRs
      my_simple= ostel.me, ostel.co, sip2sip.info, proxy.sipthor.net

      alias: ports
      my_SIP= 5060:5082
      my_RTP= 16300:19000

      At some point more likely soonventually when chided I'll try the siproxd package if it's less problematic than milkfish was on ddwrt

        after having re re read the voip wiki I am no longer certain if voip nat outbond should be "static NO" or "static YES"… and which of those means "port rewritten".  'symmetric yes' is 'static yes', right?

        in that case would I replace the "Auto created rule for LAN to WAN" with three

        wan
        192.168.40.0
        src port: udp/my_sip
        dest: *
        dest port: udp/*
        nat addr: *
        nat port: *
        static: no

        wan
        192.168.40.0
        src port: udp/*
        dest: *
        dest port: udp/my_sip
        nat addr: *
        nat port: *
        static: no

        wan
        192.168.40.0
        src port: *
        dest: *
        dest port: *
        nat addr: *
        nat port: *
        static: YES
