use Palo as an NTP device

chrismckean — Thu, 19 Apr 2012 09:00:46 GMT

Hi Guys,

We have 2 * 2050's running 4.0.7 here and I was wondering if I could use these devices as NTP servers for other devices to sync against? I've looked through the gui but can't see any way to do it so far.

Cheers

Chris

Not that im aware of.

However I think you could setup a DNAT rule to forward the NTP request made against some ip thats routed through the PA device (or ip which is already been used by the PA) into some NTP server of your choice.

For example if you only use RFC1918 addresses in your core you could address the ip of the PA device and with DNAT similar to:

srczone: inner

dstzone: inner

srcip: innerrange/cidr

dstip: PA_ip

service: udp123

translated dstzone: outer

translated dstip: NTP_ip_on_outer

along with a security rule that allows inner to reach outer for particular service like udp123 (and ip) and appid=ntp.
