SSH timing out

So the original setup of my pve was that it only had one Linux VLAN with the ff ip config:

vmbr.25
IP/CIDR: 192.168.25.2/24
Gateway IP: 192.168.25.1

When I SSH from a client in the 192.168.20.0/24 network to 192.168.25.2:22, obviously it goes through the router (opnsense) and everything is working fine.

Now, I decided to multi-home my pve with the ff Linux VLANs and ip config:

vmbr.20
IP/CIDR: 192.168.20.2/24
Gateway IP: NO GATEWAY

vmbr.21
IP/CIDR: 192.168.21.2/24
Gateway IP: NO GATEWAY

vmbr.23
IP/CIDR: 192.168.23.2/24
Gateway IP: NO GATEWAY

vmbr.25
IP/CIDR: 192.168.25.2/24
Gateway IP: 192.168.25.1

My problem is whenever I SSH from the same client in the 192.168.20.0/24 network to 192.168.25.2:22, it connects just fine but will timeout after maybe 30 seconds to 1 minute (I haven't timed it yet). I can reproduce this everytime.

When I SSH from the same client to 192.168.20.2:22 instead (source and destination in the same network), I have no issues. Obviously, this is not layer 3 so the router is out of the question in this case.

Thoughts?
