Mikrotik 2WAN - 3LAN + 2Wifi how?

Question

Mikrotik

There is a Mikrotik router on which now the 1st port is the provider, the remaining 4 + Wi-Fi is a common network + virtual Wi-Fi with a separate pool of addresses and prohibition of traffic between networks.
The configuration plans to change
1 port - the main DHCP provider
2 port - the backup provider will work if the first PPP DHCP fails
3 port - network 86
4 port - network 87
5 port - network 88
wlan1 - network 88
wlan2 - network 85
everyone looks at the Internet and has one common firewall and NAT
. the second provider is just waiting for the cable, I decided to start with one provider to divide everything into networks and stuck it.
created a bridge for the 88 main network and put port 5 and wlan1 into it, created a network, a pool of addresses, a dhcp server - everything works.
wlan2 hangs as a separate virtual port on wlan1 without a bridge, but with a separate pool, dhcp server and everything that is supposed to - it also works.
The ban between networks was made through root rules.
on ports 3 and 4, I also created a pull, a network, a dhcp server and the hell with it.
I already thought to start doing all this good through VLAN, but if I honestly don’t see the point in complicating my life like that

Answer 1

3.4 ports disabled as switch secondary from port 2?
