How to configure Omnitik as AP with SXT's as clients....

I have a networks NT1, NT2, NT3… Only NT1 network has Internet access. Between networks is Omnitik with disabled Ethernet ports. Each network has an SXT and can connect to Omnitik. I am able to ping hosts on the NT1, but not on the internet. Why? How to configure Omnitik and SXT’s to enable Internet access on other networks? Thank’s in advance.

You need to provide some more info about your net. l2? l3? (routed or not) etc.

One way is to have the AP in wds mode - Dynamic and have default bridge bridge. Also add your Ethernet to that bridge. Then put your SXT’s at station bridge, and put the link interface to bridge together with the Ethernet. Then it will be as a big Ethernet cable (switch).
