Hi,
My CRS125 setup is very simple:
/interface bridge
add name=bridge-guest
add name=bridge-main
add name=bridge-uplink
/interface ethernet
set [ find default-name=ether1 ] name=01-UPLINK-modem
set [ find default-name=ether2 ] name=02-pfSense
set [ find default-name=ether3 ] name=03-UbiquitiAP
set [ find default-name=ether7 ] name=07-GUEST1
set [ find default-name=ether8 ] name=08-GUEST2
set [ find default-name=ether15 ] name=15-living
set [ find default-name=ether17 ] name=17-Kitchen
set [ find default-name=sfp1 ] disabled=yes
/interface vlan
add interface=02-pfSense name=02-GUEST-pfSense-VLAN200 vlan-id=200
add interface=02-pfSense name=02-UPLINK-pfSense-VLAN9 vlan-id=9
add interface=03-UbiquitiAP name=03-GUEST-UbiquitiAP-VLAN200 vlan-id=200
/interface bridge port
add bridge=bridge-uplink interface=01-UPLINK-modem
add bridge=bridge-uplink interface=02-UPLINK-pfSense-VLAN9
add bridge=bridge-main interface=02-pfSense
add bridge=bridge-main interface=03-UbiquitiAP
add bridge=bridge-main interface=15-Living
add bridge=bridge-main interface=17-Kitchen
add bridge=bridge-guest interface=02-GUEST-pfSense-VLAN200
add bridge=bridge-guest interface=03-GUEST-UbiquitiAP-VLAN200
add bridge=bridge-guest interface=07-GUEST1
add bridge=bridge-guest interface=08-GUEST2
/ip address
add address=10.0.0.250/24 interface=bridge-main network=10.0.0.0
add address=10.0.1.250/24 interface=bridge-guest network=10.0.1.0
/ip dns
set servers=10.0.0.254
/ip route
add distance=1 gateway=10.0.0.254
This works perfectly on “current” firmware 6.40.3. However, when I upgrade to “release candidate” firmware 6.41rc26 (or also some earlier versions), my Ubiquiti Access Point on port 3 has a strange behavior for VLAN200: DHCP request are going fine to my pfSense router, however, the replies don’t reach it back. It’s perfectly reproducible.
Even more strange: when I connect another MikroTik switch to that same port: it works fine. But maybe because they are both on 6.41rc26…
Is this a known bug?
Thanks
