Bridge and Wireguard network config

mx flag

I have Intel NUC with WireGuard client. It works fine. I want to connect another machine via NUC by Ethernet and WireGuard.

(Router) <----> NUC (Ubuntu + VPN client) <----> Another Linux machine

Router is locked and can't be configured. Another machine locked too. Only ip addr, ping, traceroute works. No root rights.

I used bridge. Netplan config:

network:
  version: 2
  renderer: networkd
  ethernets:
    eno1:
      dhcp4: no
    enx00e04c6800e7: {}
  bridges:
    br0:
      dhcp4: yes
      interfaces: [eno1, enx00e04c6800e7]

ifconfig:

Now I have VPN on NUC but another machine don't use it. What I'm doing wrong?

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
