Server unreachable from other VLANs. Help! (alien.top)

Hey guys, not aure of this is the right place or better somewhere like r/homelab or r/homeserver.

I am in the process of setting up an Omada network and am running into VLAN issues.

Right now have 2 VLANs. Vlan 1 is the management vlan and Vlan 10 is the home vlan. Vlan 1 contains my home server and I am trying to get devices on Vlan 10 to connect to the server. It runs things like jellyfin and my home automation stuff.

I have not set up any ACLs and so as I understand it with Omada all vlans should be able to talk to all other vlans.

From the server I can ping other devices on the 10 vlan, but only devices on the 1 vlan can ping the server or connect to its services.

The server is running Ubuntu 22.04 and all the services are running in docker behind traefik for TLS with let's encrypt.

I don't really understand why the server can ping things on the 10 vlan and get a response but the things on 10 can't. And at this point I don't even know where to go next.

Any ideas???

Off the top of my head, have you set up static routes correctly? I haven't dealt with Omada before, but you should have a rule sending all traffic to your VLAN subnet to its specific interface, eg switch0.10 or whatever

This sounds like VLAN 1 is the Native VLAN, if Omada has such a thing.
