# This option allows the user to host the application on a LAN
# Default hosting is on localhost (DEFAULT_SERVER=`localhost`).
# To host pgAdmin4 over LAN set DEFAULT_SERVER=`0.0.0.0` (or a specific
# adaptor address.

# NOTE: This is NOT recommended for production use, only for debugging
# or testing. Production installations should be run as a WSGI application

Port Mapping

You can configure the router as a virtual server so that remote users accessing services such as the Web or FTP at your
local site via public IP addresses can be automatically redirected to local devices configured with private IP addresses.
In other words, depending on the requested service (TCP/UDP port number), the router redirects the external service 
request to the appropriate devices (located at another internal IP address). This tool can support both port ranges, 
multiple ports, and combinations of the two.

For example:

Port Ranges: ex. 100-150
Multiple Ports: ex. 25,110,80
Combination: ex. 25-100,80
No. 	LAN IP 	Protocol Type 	LAN Port 	Public Port 	Enable 	Configure
1	192.168.2.1	TCP	80	80		Edit  Delete
2	192.168.2.1	TCP	21	21		Edit  Delete
3	192.168.2.1	TCP	5050	5050		Edit  Delete
 	Add
