In yast I have setup/open ports
22 (ssh)
25 (smtp)
53 (dns)
80 (http)
443 (https)
465 (smtps)
993 (imaps)
10000 (webmin)
Problem is that I can’t access server/webmin from internet by typing https://my_ip_address:10000 …
I can only access webmin on port 10000 if accessed from local network. All the ports in my router are opened and pointing to internal ip address of a server. However, I find it strange that I can easy connect to port 22 (ssh) from internet but not to port 10000?
Also if I run command nmap -v -sS -O 127.0.0.1 from konsole I get the following output:

How come there are open ports (111, 631) in my fresh installation if they are not shown as open in yast firewal configuration.
Most important is why port 10000 is not showing/opened as configured in yast firewal?
This is well beyond me but here’s a drive by thought: try turning off iptables or maybe just su then “rcSuSEfirewall2 stop” to see if the routing and port forwarding works (maybe it’s not the firewall).
thank you for your reply, however I have already found the problem, there was a problem because webmin was blocking all IPs except local ones. I have just added extra IP and restarted webmin.
