On Hotspot router Hotspot is assigned to VLAN100 interface under Ether3 interface. PPTP server is enabled, internet is via leased line. To Ether3 interface further is connected hotspot network which consists of few PTP links, dumb switches and Unifi AP’s. Unifi AP’s via controller striping tagged VLAN100 and assign it to hotspot SSID. Everythings works as expected.
I want to add new hotspot location but it’s unable to connect it via PTP link so it seems best option is EoIP tunnel (there is internet connection on location). I choose PPTP VPN with EoIP. So on routers are configured PPTP VPN with two EoIP tunnels, one for ETH3 interface, one for VLAN100. VPN is working, tunnels are up. So everything works as expected BUT when I add hotspot interface (VLAN100) to bridge 2 on HS router, in log it says that VLAN100 became slave interface and hotspot is not working anymore.
So how can I send tagged VLAN100 to R2, but also keep VLAN100 as hotspot interface under Ether3 on HS Router?
I hope that everything is clear, more or less
