vpn3005 NTP synchronization failed

I'm unable to synchronize with a NTP server, i have try so many of them. Actually i have two VPN3005, one of them is able to sync with a NTP server, the other just don't syn at all.

I'm just wondering, are there any other setting which i need to allow a VPN3000 to syn with a NTP server?

look forward for any reply, thanks

Re: vpn3005 NTP synchronization failed

If the NTP server is on the Public interface of the 3000, then you need to add Rules to the Public filter to allow NTP traffic in/out. By default the Public filter only allows IPSec/PPTP/L2TP/NAT-T type traffic in.

Check out the other rules under Config - System - Policy Mgmt - Rules for the format, and then create new ones for NTP in/out. Then add them to the Public filter under the Filter section and "Assign Rules to Filter"
