в линуксе есть замечательная штука gretap - простейший ethernet тунель, умеет фрагментировать, для шифрования можно завернуть в ipsec ip link add grelan type gretap local 1.2.3.4 remote 2.3.4.5

ifconfig давно уже депрекейтед используйте ip ip link add name vlan15 link eth0 type vlan id 15 ip link set dev vlan15 up ip addr add 192.168.1.4/24 brd + dev vlan15 намного быстрее создаются вланы

Да. У нас используется один интерфейс для терминации абонентских вланов с влан на пользователя.
