I can access the services behind SWAG from the internet. That’s fine.
I can’t reach the SWAG dashboard.

A ping from 192.168.200.21 to 192.168.100.11 works!

ping 192.168.100.11

When I type http://192.168.100.11:81 into firefox nothing happens.
Firefox try to get a connection. After some minutes I get the Error message Der Server unter 192.168.100.11 braucht zu lange, um eine Antwort zu senden. (The server at 192.168.100.11 takes too long to send a response.)

Any ideas what the problem could be?
Which ports does the SWAG Dashboard respond to?
