Mikrotik Why doesn't UPnP work?

Question

Computer networks

Good afternoon. There is such task (for me a little difficult)

There are two providers. Both access via PPPoE. Created two bridges, distributed ports among the bridges.
eth1-wan1(dynamic Ip)
eth2-wan2(static Ip)
eth3- LAN1(10.0.1.0/24) -> WAN1
eth4,eth5 - LAN2(10.0.0.0/24) -> WAN2

Marked connections, added routes so that each the provider sat in the lokalke.
I also allowed LANs to communicate with each other
. But only one of the providers has a static IP. Opening ports manually is very dreary, I used UPnP before. But when I added a second provider, upnp stopped working. NAS (10.10) simply does not see the router with UPnP. Tell me how to fix?

Answer 1

The issue was resolved. It was necessary to specify interfaces for UPnP according to this article

Answer 2

Why do you need upnp? what problem should be solved?
It's easier for NAS 1 port to forward and that's it
