dnat porta 53_tcp

giuseppe121
ASG 8,202,
I created a DNAT for ssh, 22, and 53 for the service DSN, to my server behind ASG.

If I telnet to port 22 works, if I telnet to tcp 53 is not working, why?
There 'a mistake?

Port 53 is open locally, because if you launch NMAP is present.

thanks

    You can check with tcpdump, but my guess is that the Astaro is doing what it should, and that it is the server at ???_80.6 that is not responding.

    Not sure why you're using the SNAT instead of a masquerading rule...

    Cheers - Bob
