      Can someone just confirm that 1:1 NAT overrides any outbound NAT setting you may have ?

      We have a customer on a pair of pfSense firewalls and the servers are using private 10.0.x.x addressing and we use 1:1 NAT (VIP Other) to map a public IP to a private IP.

      Customer has many servers all running VoIP and audio works fine.

      Installed a new pair of firewalls for customer, same setup but for some reason audio is only one way and for some of the packet captures it looks like outbound traffic from the servers is not being translated to the public IPs.

      Checked all settings and cannot see a difference and any testing I do on a server behind firewall eg. SSH etc. works fine.

      Any suggestions where to look most welcome.

          @jms123 said in 1 : 1 NAT and outbound NAT:

          1:1 NAT overrides any outbound NAT

          All traffic originating from that private IPv4 address going to the Internet will be mapped by 1:1 NAT to the public IPv4 address defined in the entry, overriding the Outbound NAT configuration

          Only install packages for your version, or risk breaking it. If yours is older, select it in System/Update/Update Settings.
          When upgrading, let it finish. Allow 10 minutes, or more depending on packages and device speed.
