This will override the Outbound NAT<\/strong> settings. Conversely, all traffic initiated on the Internet which is destined for the specified public IP address will then be translated to the private IP. Then it will be evaluated according to the WAN firewall ruleset, and if the traffic is permitted by the WAN rules, it will be passed to the internal node specified in the mapping.<\/p>\n\n\n\n In this scenario, the server should be accessible via the public WAN network. Thus, we will have an additional IPv4 address in each WAN network. The addresses must match the IP network and be known to the clients (e.g. via DNS).<\/p>\n\n\n\n The implementation in OPNsense is somewhat complicated because for practical purposes, the firewall requires:<\/p>\n\n\n\n Virtual IPs and firewall rules have articles devoted to each settings. Assume that 192.168.2.7 is the virtual IP for the web server.
