[edit] 1 Introduction

"Port Forwarding", "DMZ" and "Static NAT" are all redirecting firewall rules.

  • "Port Forwarding" : forword packets on certain port(s).
  • "DMZ" equals "port forwarding on all ports". Visits to WAN interfaces will be redirected to the DMZ host(except of the excepted ports).
  • "Static NAT" provides one-to-one NAT for local hosts.

[edit] 2 Port Forwarding

  • Forwarding: map a WAN port, port range or all traffic to a local host.
    • Type: if type is "all", "source port" and "target port" shall be blank.
    • WAN: target WAN IP address.
    • Source Port: target port to the WAN interface.
    • Target IP: "redirected to" local host IP.
    • Target Port: "redirected to" port, leave it blank for same as the source port.
    • NAT Reflection: enable or disable NAT reflection.
    • Forward to VPN: When enabled, you can forward traffic to clients behind a VPN tunnel. Source IP will be translated to LAN ip address, which can be routed back via a VPN tunnel.

[edit] 3 DMZ

  • DMZ: port forwarding on all ports.

[edit] 4 Static NAT

  • On "WAN" zone, this rule can translate local traffic to a WAN ip address.
  • On "LAN" zone, this rule can translate internet traffic to a LAN ip address.

  • Single: a single IP(192.168.10.100) or subnet(192.168.10.0/24).
  • Range: an IP range.
