Logviewer does not show data from hairpin rules

Can you show us your firewall and NAT rule? Maybe your filter in logviewer is not accurate or you have old connections, pinned to old firewall rules. Check diagnostic and look for NTP connections.  

I checked the diagnostics only found 1 NTP connection which is showing the same amount odf data as yesterday.

The NTP firewall and NAT rules as requested.

Actually this firewall rule should not hit for your NTP traffic at all. 

If you add to this firewall rule the Zone LAN to Destination (or what ever your freenas zone belongs to), it should match. 

Do you mean firewall rule or NAT rule? I had the freenas in the firewall rule and that did not work because the NTP users have external addresses as their destinations for ntp traffic.

I have changed the NAT rule and it is no longer used, the default NAT rule passes the NTP traffic.

I have deleted the NAT rule and created a linked NAT which shows activity. When reviewed in logviewer the traffic is still going out the WAN interface,

I was talking about the Firewall Rule. 

The Firewall Rule should be: 

Source LAN

Destination LAN 

Destination Host: Freenat.

NAT was fine in your initial screenshot. 

I will try that setting again, last time it did not pass any traffic.

Ian

Changed the rule to your recommendation. The firewall is not registering any traffic, the NAT rule is. There is nothing in logviewer.

The overnight report shows lots of UDP 123 traffic, not classified as NTP. The logviewer shows the traffic is all going out through the default NAT rule not the higher priority NTP rule.

I made further changes this morning in an attempt to see if the hairpin is sending traffic to the internal NTP server, but failed because the logviewer shows all traffic going out to the internet.

Hi folks,

I have rebuilt my rules using trial and error and now have the logviewer is showing entries regarding the hairpin. Next trick is to get the freenas server to respond to ntp queries.

Ian

After all that, the freenas does not provide an NTP function. So off to get a PI.
