Já už na to právě koukám takovou dobu, že už nic nevidím.... Zkoušel jsem různý kombinace rozhraní bez bridge, s bridge, nic nepomáhá.
Konfigurace je zhruba takhle:
/interface ethernet
set [ find default-name=ether5 ] comment=wan
/interface wireguard
add listen-port=33333 mtu=1420 name=wireguard1
/interface vlan
add interface=ether1 name=vlan99 vlan-id=99
/interface list
add name=LAN
/interface list member
add interface=wireguard1 list=LAN
add interface=vlan99 list=LAN
/interface wireguard peers
add allowed-address=10.200.0.2/32,192.168.100.0/24 interface=wireguard1 name=1 public-key="xxxxx="
add allowed-address=10.200.0.3/32,192.168.100.0/24 interface=wireguard1 name=3 public-key="xxxxx="
add allowed-address=10.200.0.4/32,192.168.100.0/24 interface=wireguard1 name=3 public-key="xxxxx="
/ip address
add address=x.x.x.x/30 interface=ether5 network=x.x.x.x
add address=192.168.100.1/24 interface=vlan99 network=192.168.100.0
add address=10.200.0.1/24 interface=wireguard1 network=10.200.0.0
/ip route
add disabled=no dst-address=0.0.0.0/0 gateway=x.x.x.x routing-table=main suppress-hw-offload=no
