mmm..I think you don’t understand me, is it possible to connect ap bridge with ap bridge, if yes than what configuration i need??? Maybe static WDS, with dynamic WDS i had no any resultat. And is it possible to connect two Virtual AP with each other?

I have done this. You just need to turn on dynamic WDS on both virtual ap’s. I also turned on WPA for security. Also make sure you set the WDS AP to join the correct bridge.

Use WDS.

Enable dynamic, then just use the same band, SSID and frequency.
If you want to use static, add to each AP /interface wireless wds entry about remote end.
