Hello,

I'm facing some DHCP relay issues on mikrotik routers with 7.14.3 version.

The configuration :
add delay-threshold=3m dhcp-server=172.17.0.40,172.17.0.41,172.16.208.20,172.16.208.21,172.30.220.20,172.30.220.21 \
disabled=no interface=VLAN748 local-address=10.5.25.1 name=VLAN708-Relay
add delay-threshold=3m dhcp-server=172.17.0.40,172.17.0.41,172.16.208.20,172.16.208.21,172.30.220.20,172.30.220.21 \
disabled=no interface=VLAN749 local-address=10.5.25.129 name=VLAN709-Relay

Almost of the devices are working fine, they catch an IP address from one of the DHCP servers.

But the some devices, printers and Wifi AP, do'esnt have IP address.
I saw with packet sniffer and dhcp debug logs, the mikrotik isn't sending dhcp discover received from printers to DHCP servers.

I attach you the screens of working and no working terminals dhcp debugs
