I'm trying to get my head round VLAN offloading on V1.9.0 of a ERPoe-5 router. I'm new to EdgeMAX -- and inially setup through the GUI, but don't mind using the CLI if I need to.
I've got a local subnet on eth1
I've got another subnet on eth2 and aliases of eth2 for a couple of VLANS (each corresponding to a SSID coming from a unifi AP).
I've not got any exotic firewall rules, just a few for accepting/dropping based on destination addresses/connection state between subnets.
When I turn on VLAN offloading pings get through between networks, but other traffic doesn't. If I turn it off it traffic can flow freely as intended.
I've had a good search through the forums and couldn't find a definitive answer. -- There's discussion about not using offloading if for firewall rules that modify -- but I'm not sure if drop/accept fall in that category? There's similar discussion here, but unlike this topic https://community.ubnt.com/t5/EdgeMAX/Vlan-offload-not-work-properly/td-p/1197776 I don't have any bonded interfaces, and I'm not sure how offload has changed in later firmwares.
I'd have thought if the offload hardware can handle accept/drop based on src/dst fields of packets it could look at the vlan tag too?
