Enable DNS only for router itself
Posted: Thu Dec 29, 2022 4:23 pm
Hi,
I would like to enable DNS only for the router itself to resolve the smtp server. If I enable input for port TCP/UDP 53 but drop all the rest the dns does not resolve the Ip Adress of the mail server and cannot send the email. Can you help me setting up the firewall rules?
Thanks in advance.
