Why can’t LUbuntu reach the OPNsense LAN IP
Hola!
On the project I started last week, I am encounter (as everyone else does) problems here and there I am troubleshooting and going through. I will keep track on them on a shorter way.
The problem was that my Lubuntu VM couldn´t ping/connect to the OPNsense LAN IP, even though both were suppossed to be on the same subnet ( a virtual bridgde I with a static IP).
The cause was that I configured on the wrong subnet (my router IP) insetad the vmbr1. The reasons I am doing this are [here] (https://facyber.me/posts/blue-team-lab-guide-part-2/) on this blog is presented a blue team lab I am replicating on my own way.
The solution that helped me for this case was to ensure the network device net1 in Proxmox was conected to the vmbr1 and amnually set the LUbuntu to the vmbr1 Static IP address with this comnads:
sudo ip addr flush dev enp0s19
sudo ip addr add 10.0.1.2/24 dev enp0s19
sudo ip route add default via 10.0.1.254 dev enp0s19
