How do I enable SSH on LAN but not WAN ?

[Spiky_Gladiator]

I'm wondering how I can enable SSH but only on the LAN but not on WAN ?
Does enabling SSH only opens it to the LAN but not WAN by default as you need to Port Forward it ?

I need to use SSH to install a text editor then edit fstab file until there's another easier way I can do via the web interface ?

Hi,
all ports are, by default, closed to the WAN side so you may enable SSH with confidence and it will only work on the LAN side.
