Vlan - pc (1 port), router (3 ports) - how to connect a pc and a router on 1 port, mark the other 2 ports as vlan?

Question

linux

There is a PC with one network interface. There is a router with one network interface eth0 and three ports on it, each port can be tagged as vlan. Here is a screenshot of what the router allows you to doActually, what needs to be done: connect the PC to the router with one of the ports, make vlans eth0.1 and eth0.2 on the PC, tag the remaining two ports on the router vid 1 and vid 2 (we will get vlan1, vlan2 interfaces) and, accordingly, drive all traffic over pairs eth0.1-vlan1 and eth0.2-vlan2 (this is necessary in order to use the iptables rules on the PC to steer the traffic that goes to the router). Will such a link work? How do I configure the router so that all traffic from vlan1 and vlan2 somehow gets to the third untagged port and flies to the PC port? Do I need to configure the PC somehow, so that all traffic that arrives at eth0 is distributed over eth0.1 and eth0.2 in accordance with vlan tags?
ps: PC and linux-based router, ebtables, iptables work.
