Hi all, i've two Zyxel USG Flex 200 and two Mikrotik Cube 60Pro ac on Site A and B. What's the best way to realize a site to site connection via point-to-point wifi? Site A and Site B have both several VLANs that should be accessed from the other site by security policy rules. The Mikrotik Cube 60Pro's are in bridge mode and "act as a network cable". Site A: vlan 50 10.50.0.0/16 as example USG Flex vlan 50 10.10.50.1, vlan 70 10.70.70.1 Mikrotik Cube 60Pro vlan 70 10.70.70.10 Site B: vlan 60 10.60.0.0/16 as example USG Flex vlan 60 10.10.60.1, vlan 70 10.70.70.2 Mikrotik Cube 60Pro vlan 70 10.70.70.20 Should I add the Mikrotik Cube 60Pro in a Transfer VLAN 10.70.70.0/24? Both sites have it's own DSL connection. Could the dsl connection be used for backup on the other site? Is a Site-to-Site VPN as Backup connection possible? Do I need a static route in Site A USG Flex 10.10.60.0.0/16 → 10.70.70.2 and Site B USG Flex 10.10.50.0.0/16 → 10.70.70.1? Do I need a static route for Mikrotik Cube 60Pro in the transfer VLAN 70? USG Flex Site A 10.70.70.0/24 →10.70.70.10, Site B 10.70.70.0/24 → 10.70.70.20) Could I manage access via security policies in this setup? Thanks! Best, baba

The site to site is for VPN the other can I think be done by just a routing rule I think their are three ways you can do this

Site-to-Site connection via Point-to-point wifi
