Weird behavior

[dterjhan]

Hello,

I've been toying with OPNsense as my main router for 2 years now, but I've recently been having problems with certain applications

I've recently moved houses and made a new install with 24.1
I've got a single WAN setup, and multiple LANs set up.

For now I'm just trying to get all my services working right before configuring my second and third LANs

My network is as follows :

ISP GPON => OPNsense WAN PORT => OPNsense LAN PORT => LAN computers

I'm running a VM, with docker inside, on one of my computers.

I'd like to access my services as I've done before on 23.x

I've set up a gateway and a static route to the subnet on my computer. I can access my VM without pain from any other computer on my LAN

When I try to connect to one of the services running inside Docker, it either works perfectly or not at all.
My Jellyfin LXC container is working perfectly, but I can't upload anything to my Immich container.
I can SSH into my LXC container, but the connection is dropped after a few seconds.

If I completely disable OPNsense's firewall, everything works as expected

I've tried adding some rules to allow traffic from my server's subnet to my LAN, and from my LAN to my server's subnet, but nothing works until I disable the firewall entirely

I've read countless forum posts, and heard about asymetric routing, but nothing I've tried up until now has worked

I feel like I'm loosing my mind here, and I'd really appreciate if someone could help me get everything right

Thanks a bunch

Here's a simplified diagram of my network

And a screenshot of the rules on LAN
