>How do you solve this problem ?
Iterative fact checking, from the lowest levels of the network stack
to the highest.
- Are the devices actually connected where you think they are?
- With the tunnel disconnected, does your phone connect to the
camera?
- Is your Wireguard tunnel set up properly?
- Can your phone ping the wg0 address with the tunnel active?
- Can your phone ping other .100 devices with the tunnel
active?
- Does your eth0/wg0 machine have IP forwarding enabled?
- sysctl net.ipv4.ip_forward=1
- What does packet tracing show?
- I.e. `ngrep -d wg0 .\* icmp` or the tcpdump equivalent, also
against eth0 for the wireguard UDP port.
- Does the mobile App actually support remote (routed) cameras or
just on the local network?
