NTP Server is filtered

[lmoraperez]

Greetings, for a while, the NTPd service is filtered by OPNSENSE, I have my DNS and DHCP server independent and I only use OPNsense as a firewall and I only have the NTP service active but when I try to update a client against OPNsense it is not possible to update.
Sorry my bad english.
