GL-B1300 Physical Ethernet Port Guest LAN

Technical Support for Routers

Hi all,

The GL-B1300 has two physical ethernet ports.

Is it possible to have the 1st ethernet port on LAN and the 2nd ethernet port on Guest Network?

Thank you!

Perfect, that worked beautifully. Thank you hansome!

If I want to make the other port (end port) the guest network, what entries would I need to change?
