Dear Support,

 

Kindly assist us in established a successful Site to Site VPN connection via Tplink ER605 (Remote Site Router) to Sophos XGS Firewall (Head Office), we have tried all knowledge base available but have challenges in connecting this two routers.

 

Further, we have noticed that most of the vpn option which were available before joining to controller are disappeared and very fewer vpn option available.

 

Regards

Sayeed

those screenshots didn't say much, i was wondering what you are missing when configuring the vpn on the omada controller.
you have to press advanced in vpn config for more options.
