How to change default gateway

Server needs to have a single default gateway. DHCP servers will automatically assign a default gateway to DHCP configured NICs, but NICs with configured static IP addresses will need to have a manually configured default gateway. This can be done with a simple command. This example uses a newly installed wireless interface called wlan0, most PCs would be using the standard Ethernet interface eth0.

route add default gw 192.168.1.1 wlan0

In this case, make sure that the router/firewall with IP address 192.168.1.1 is connected to the same network as interface wlan0!

Once done, update your /etc/sysconfig/network file to reflect the change. This file is used to configure default gateway each time Linux boots.

NETWORKING=yes
HOSTNAME=actsupport
GATEWAY=192.168.1.1
