      I am configuring pfSense for an onsite PBX and am following this guide:
      https://docs.netgate.com/pfsense/en/latest/nat/configuring-nat-for-a-voip-pbx.html

      This is working well and the guide is simple to follow.

      My ISP has supplied me with 5 networks that the calls will originate from being:
      X.X.X.X/24
      X.X.X.X/25
      X.X.X.X/26
      X.X.X.X/27

      I have added these to an alias called SIP_Trunks.

      In the guide in the "Manual Outbound NAT" section, under the 5th dot states:
      "Destination: Network, SIP_Trunks – Or Any for the type if the SIP trunk IP addresses are not known"

      When setting this what network suffix should I use considering my SIP trunks have a range of suffixes (/24 to /27)?
      For the previous entry when specifying my PBX I used /32 PfSense1.PNG

      Thanks in advance.
