    Solved jail with network access

    If I want to setup a jail during the freebsd install process, I would have to assign the jail an IP address on the same subnet as the host itself so that I can avoid needing to NAT? Is that correct? Or is there another approach I could use? I'd like to have everything configured during the...

    Using VLANS to connect VNET jails to WAN?

    I know I've started a few threads here about odd networking experiments that I am running in VNET jails. Still haven't figured anything out about those when using epair(4) interfaces. So I thought I'd try a different strategy using VLAN interfaces instead. And this time, include a (janky)...

    I have a vnet jail for my physical NIC. In order to start the pf service in that jail, I had to add a devfs.rule to unhide /dev/pf. I also have wireguard jails which I intend to do the same, and connect them to my NIC-jail. (everything is vnet). Does anyone know if this is a bad idea? Will...
