Use the UTM as an NTP server

Heli0s
Is it possible to use the UTM as an NTP server? I've created a firewall rule that allows NTP to the UTM, but when I ask a Windows machine to sync time, I get an error and the firewall logs show a dropped packet going to port 123.

Do I have to set the computers to sync off the UTM or is it possible to redirect all requests to port 123 to the UTM? (I'd rather do the latter)

    Hi Heli0s,

    I've noted periodic problems with systems on my home network using NTP to correct/update their time. Like you, I wanted a way to redirect all outbound NTP requests to the UTM itself. My first attempt was a policy route to redirect NTP requests, but I couldn't get it to work. After searching the webs, I eventually found this post and decided to give your method (destination NAT) a go. It took a bit of trial and error--initially was stumped by "any" address object errors--but eventually found a configuration that works great. It's nice not to need to manually re-configure each system using NTP.

    I'm including a screenshot of my destination NAT rule that handles this, in hopes it helps others. Thank you!
