![]() LAN is the local side of the internet (home network), and assigned a private IP Addresses, one per device on the network. WAN is the public side of the internet, its assigned a public IP Address. WAN is not Wireless Area Network, thats WLAN (Wireless Local Area Network) and not a common term. Local Area Network (LAN) Port - the port on your router that connects you to the home network. Wide Area Network (WAN) Port - the port on your router, that connects to your modem with an ethernet cable. In this part we neet open the ports of the WAN There we write the IP of the Server that we want to use PosgreSQL Usually is found in the section of Port Forward. In this case we can open the port of the Router 2. The second step, is we open the ports that we want to use, This configuration example demonstrates two different types of NAT configuration that can be used to translate the public IP addresses servers to the corresponding private IP addresses for inbound and outbound traffic In this use case, the two Servers have private IP addresses and are located behind theoptional network of Router 2 We find the the IP of our Router 2 (here takes and we put the we put them in the DMZ then click Save. They are often used a simple method to forward all ports to another firewall/ NAT device.Ĭlick: Forwarding > DMZ > Enable/Disable. A home router DMZ host is a host on the internal network that has all UDP and TCP ports open and exposed, except those ports otherwise forwarded. Strictly speaking, this is not a true DMZ. Open the web browser and type the IP address of the Router 1 of the device in the address bar ( Press Enter.Ī DMZ (demilitarized zone) on a home router refers to a DMZ Host. ![]() We require setup the IP of the Router 2 in a zone DMZ Īnd the Second Router 2 is connected with our Router 1. Let us consider as an example that we have two main servers with private IP addresses on the optional network. NAT for Public Access to Servers with Private IP Addresses on the Private Network Make sure iptables is not blocking communication, open port 5432 Refer to the FAQ for information on accessing restricted ports using an SSH tunnel or opening ports in the server firewall. For development purposes, you can also use a VPN or SSH tunnel. If you must make it accessible over a public IP address, we recommend restricting access to a trusted list of source IP addresses using firewall rules. For security reasons, we do not recommend making the database port accessible over a public IP address. As a result, you will only be able to connect to your database nodes from machines that are running in the same network. IMPORTANT: By default, the database port for the nodes in this solution cannot be accessed over a public IP address. To connect to PostgreSQL from a different machine, you must open port 5432 for remote access.
