Server unreachable from other VLANs. Help!

Hey guys, not aure of this is the right place or better somewhere like r/homenetworking 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??? Pointers?

    Thank you so much. I just spent too much time looking at it yesterday. Fresh eyes and the gist of this got me there.

    Turned out to be multiple issues. The switch port the server is connected to was not a client port like you said. I just totally overlooked this. I has all my ports set to client ports for their specific device just not the server…

    And then it turns out I has the server configured to have a static IP with a subnet mask of /16 instead of /24. Fixed those two things and bam! works as expected.
