Connect to OPNsense VM

[spetrillo]

Hello all,

I have built an OPNsense firewall vm on my Proxmox server. The vm was built using PCI passthrough for the Intel I350 network card. The first port on the Intel card is set with a vlan of 1, for my mgmt network. I connected an ethernet cable to that port and ran it to a USB network adapter on my laptop. I set the adapter on my laptop to vlan 1 and I can ping the new firewall's IP address on the LAN interface. I can also get IP from this firewall via DHCP, however I cannot connect to that IP via the browser on my laptop. Is there a trick to doing this? I would like to be able to configure the firewall vm before going live with it.

Thanks,
Steve

There's a post from meyergru in the tutorials section about OPN on proxmox.
FWIW, he recommends passing bridges...
I personally switched from passthrough to bridges after that (mostly because it facilitates moving configs across VMs).

Ping+DHCP is a good start. Weird that HTTP(S) doesn't work.
Not assigning an interface to the physical device is recommended (removes untagged traffic). Compliant?
You could try using another VLAN ID (1 tends to be a bit special, especially if you still have untagged traffic).

In any case, you have access to the OPNsense console in PVE. You can do basic troubleshooting from there.
