Traffic is wrapped in a tunnel between the two ends, so the network in between only sees the tunnel.

01 Security

Is port 7802 dangerous?

We have no specific security note for port 7802. Its risk depends on the program actually listening on it. General advice for vpn, tunnels & proxies services:

  • Patch VPN gateways quickly: they are a top initial access target.
  • Use certificates or MFA rather than shared secrets.
  • Investigate unexpected tunnels and proxies: they are also attacker tools.

03 Check it

Which program uses port 7802, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7802'      # process listening on 7802
sudo lsof -nP -i :7802

macOS

sudo lsof -nP -i :7802

netstat -ano | findstr :7802

From another machine

nmap -p 7802 -sV <host>
sudo nmap -sU -p 7802 <host>
nc -zv <host> 7802

Block it in the firewall
