Yes, all these boxes are connected to our LAN with their ext_ifs. Also, one
of them has a switch and a PC connected to its int_if, other int_ifs are
"status: no carrier".

Well, as I understand, in my case, STP should be enabled mainly on
TAP-interfaces as it would eliminate the scenario where, for an example,
ARP-requests from 192.168.1.1 for 192.168.3.1 reach 192.168.2.1. Have I
understood it correctly?

Well, let's try ;)
The machines stand like this:
192.168.8.15/24
- GW/NAT -
192.168.1/24
|| 192.168.8.16/24
== 192.168.8/24 == == - GW/NAT -
|| 192.168.2/24
192.168.8.17/24
- GW/NAT -
192.168.3/24
