      @johnpoz @stephenw10 You can see what happens igb1.50 (vlan) is working.
      Then i add a LAN interface to listen on and you see it falls over. why is the lan interface adding 0.0.0.0 instead of the lan address? this is a bug right?

          You only need to listen on your interfaces you want to serve time on... My guess since you mention vpn, is you went to manual and now your not natting loopback, so when an application tries to use that as source to talk pfsense doesn't nat it and you can not talk..

          So the only why ntp would be able to talk to ntp servers is if bound to interface, the 0.0.0.0 is bind to all... Post up your outbound nats, Bet you a beer you don't have loopback natting..

                @johnpoz I want to listen on the lan interfaces for switches/access point devices and vlans for end user equip.

                I have the same config for each of the VPNs and they work

                  Exactly I only listen on a few of my local lan side interfaces... I don't see ::1/128 listed there.. maybe its trying to do ipv6?

                  I really don't see the point of doing manual outbound nat.. Why would you not just use automatic, and set hybrid for the stuff you want to policy route out your vpn..

                  Do you not have ntp listening on an interface that you nat?

                      So you have a vip on igb1?

                      I would sniff on your wan - do you see traffic going out to those servers? With source IP natted to your wan IP?

                      Is your default route out your wan, or via vpn.. IE you pulled routes?

                          Snort huh... yeah could be problematic..

                          But its a given if your ntpd can not get into sync by talking to the ntp servers you point it to, either direct or pool then no clients would sync with it. ;) since its not a valid time source until it has gotten into sync with valid time source.

                              So the problem was I thought you were not natting.. Which prob has something to do with manual nats and all your vpn interfaces...
