Hi Jorge,

 

 

It is not secure to allow anybody from the internet tot access your link controller through SSH, this access should be blocked.

 

You can do this by defining a port lockdown on the Internet-facing self IPs. Choose 'allow custom' and allow only tcp 53, tcp 4353, udp 53, icmp.

 

You can also define an IP-filter to limit ssh to only specific IP-addresses and block the others.

 

 

Regards,
