Appendix 6 – How to change IP address/netmask of Router LAN port via u-link

VPN connection

A6 - Change LAN IP address/netmask of a remote Router via u-link VPN connection

Situation (Example):

▪ Current IP configuration of remote Router:

LAN port IP/Subnet: 192.168.1.110 / 255.255.255.0

WAN port IP/Subnet: 192.168.99.206 / 255.255.255.0

Requirement:

▪ The LAN port IP/Subnet shall be changed via u-link to:

IP address: 192.168.50.254

Subnet mask: 255.255.255.0

Solution:

➢ Connect to the remote Router via u-link.

▪ The u-link VPN client (PC) now has got route

settings how to access the IP networks

192.168.1.0/24 (Router LAN) and 192.168.99.0/24

(Router WAN). See upper screenshot.

▪ The Routers Web interface can be accessed via

LAN IP, WAN IP or via the Routers u-link VPN IP

(see upper screenshot). Due to the fact that we

want to change the LAN-IP we may not use the

current LAN-IP for accessing the Web interface

but we can use the Router VPN IP.

➢ Open the Routers Web interface by using the

Routers VPN IP.

➢ Goto menu IP configuration.

➢ Change IP address data of LAN port.

➢ Click button ‘Apply settings’.

▪ Now the new LAN-IP address is active and the

connected devices at Routers LAN port must be

adapted to the new IP range.

➢ Save the configuration (Menu System → Save).

Note about provided accessible networks:

If the Router is connected to Internet via DHCP-enabled WAN port then the

WAN network will not provided as accessible network (only the LAN side).

If the Router is connected to Internet via WAN port with static IP address then

both network sides (LAN and WAN) are provided as accessible networks.
