Mwan3 - source port based routing doesn't work

[csharper2005]

Hi guys!

Input data:

• OpenWrt router with 2 wireguard cilents
• 2 providers (dynamic private IPs)
• wireguard server 11.11.11.11
• mwan3 with the following rules on top:

config rule 'wg_wana'
        option sticky '0'
        option use_policy 'wana_only'
        option dest_ip '11.11.11.11/32'
        option family 'ipv4'
        option src_ip '0.0.0.0/0'
        option src_port '2222'
        option dest_port '51810'
        option proto 'udp'

config rule 'wg_wanb'
        option sticky '0'
        option use_policy 'wanb_only'
        option dest_ip '11.11.11.11/32'
        option family 'ipv4'
        option src_ip '0.0.0.0/0'
        option src_port '3333'
        option dest_port '51810'
        option proto 'udp'

Expectations:

• 1st wg client should connect to a wg server throw the 1st provider (WAN_A)
• 2nd wg client should connect to a wg server throw the 2nd provider (WAN_B)

By the fact, both clients connect to a wg server using WAN_B, despite of mwan3 rules.

What is wrong with this configuration and what sould be changed? Thanks in advance for your ideas.

The reason is clear as day. All is working.
