This is particularly annoying because to my knowledge, it seems to be the only method to making DHCP requests working for Orange french ISP provider (set priority of 6 on UDP port 67 for VLAN 832). Bridge filters on same configuration works very well on RouterOS 6.48.x and 6.49.x.
Packets and Bytes remain to 0 (screenshot was made with 6.49.2 for illustration purpose, but the problem of 0 counters are for RouterOS >= 7.x).
NB : I even tried more generalistic rules without any criteria except
Code: Select all
chain=output
Configuration
Code: Select all
