Forwarding, DMZ and Static NAT

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.

2 Port Forwarding

• Forwarding: map a WAN port to local host.

• • 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.

3 DMZ

• DMZ: port forwarding on all ports.

4 Static NAT

You need to define "Local IP" and choose a public IP.

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