I had no problems with the IP-address:
OK, now only captain tcpdump can help us.
Let’s see what it looks like.
tcpdump -ni eth5 host 192.168.0.53(my client) and port 4444
Here it is important not to filter for the UTM (192.168.0.1), because we want to know how the client wants to reach the UTM.
Nice, chrome ignored my dns server and resolves the utm with it’s wan IP.
Normally this is not a problem. But my UTM has a transfer network to my provider router, so I can’t reached the webadmin portal.
Have a nice day!
