General Discussion / Can't connect to gateway
February 14, 2025, 10:12:40 AM
Hi everyone

I am a first timer so please have patience.

I just setup OPNsense for the first time and am struggling.
I have it setup in a Proxmox VM (I know, will buy dedicated hardware at some point) that passes linux bridges from the NIC. Additionally I have an Aruba Instant On 1830 switch (not happy with the admin tool so will change that as well, recommendations welcome).

I have setup 7 VLANs and connected them on port 4 (no LAGG as I couldn't get it to work that way). It is connected to the switch on a trunk port, that has the VLANs assigned as tagged.

I temporarily set the firewall rules to allow all traffic.

The devices get DHCP leases and on the LAN (Port 2) I can connect to them. But as soon as I connect through an untagged port on the switch I cannot even connect to the gateway. Do you have any ideas on why this could be?

Thanks for the help in advance.
