Thank you for the hint, i try to set outbound NAT but without any results.

I think i have a cmos battery problem on server....

juniper

tracing internet interface i see:

And there is no answer in that trace.. A cmos battery has ZERO to do with not getting any answers.

On your query you see via your internet interface what is the source IP? Did it get changed to your public IP? via your outbound nat?

Can not sync time if you do not get any answers.

example - here is sniff showing answers to queries

You can send queries all day long - if you don't get answers then no ntp can not set time. You not showing what your public IP is.. So maybe its sending it with your rfc1918 address? See mine starts with 64.43 - this is pfsense wan IP.

i have only an internet interface that isn't WAN (now is disabled for migration reason and i use another internet interface, on firewall i have only outbound rules for that interface) and my interface ip is: 80.19.236.234

in trace i see:

it's the same address

johnpoz

See my edit on above post - if you do not not get answers then no you can not set ntp time. Your just showing queries for time, no answers. Also why you seeing bad cksum?

You sure your sending out the right interface - you see inbound traffic on this interface to your public IP 80.19.x.x?

juniper

yes i don't receive answers, i try to disable hw checksum and i have the same result (tcpdump with -n option):

I only see 1 response from 212.45.144.88, set that as you server - do you get answers from that when doing normal polling?

And are you getting answers? Your reach is 0 (zero) you can not sync time if you do not get answers...

You seem to be sending out the queries - but if you do not get an answer, then no you can not sync... That has ZERO to do with pfsense.

What is this

If your sending ref of 2036 - maybe the ntp server your asking just ignores you and does not answer. See my reftime

Looks like your normal queries are using a date of feb 7, 2036... Adjust the date and time on your pfsense box to be atleast close! ;)

juniper

reftime=00000000.00000000 Thu, Feb 7 2036 7:28:16.000 is not the problem at initial sync...

i've configured another internal ntp server that works and pfsense box ntpd using that server works...

johnpoz

So your saying ntp works talking to your ntp server locally, but does not get answers remotely? But it not getting answers is related to what? How is an ntp server not answering something you clearly sent out pfsense issue? If it was something wrong with the query - then your local ntp server wouldn't answer it either.

Your local ntp server taking a different path to sync to outside, is it not syncing to outside?

juniper

my local ntp server reach internet through pfsense box and works fine, sync and serve.

pfsense box using my local ntp server works fine:

Why would you have it marked pool when clearly its not?

So my question is does this ntp server take the same "path" to the internet that pfsense would take on its own? Or are you routing this traffic different pfsense local traffic would take - ie the default route/gateway?

You stated

i have only an internet interface that isn't WAN (now is disabled for migration reason

juniper

for pool configuration is just an oversight.

ntp server take the same path of pfsense (not WAN)

johnpoz

Well that makes zero sense - is the ntp server using the same servers you were trying to sync pfsense with?

You sure the ref time thing is not an issue. I don't recall every seeing such a ref time.. it is one of the rollover dates.. Now that your ntp is syncing and your time is good. What if you change to from your local server to external on pfsense?

So your saying that when you ntp server that is internal talks to the outside to sync its time its using the same bath and "the same source ip" as when pfsense itself goes out to the internet to talk to ntp. That 80.19.a.b address, your sure its not say 80.19.a.c ? or something like that?

Makes not sense that ntp server would answer your client, but not the client on pfsense?

What version of pfsense are you using? 2.4.3p1?

juniper

0_1531055737710_Screenshot from 2018-07-08 15-15-04.png

yes the same servers.

mtr from my local server:

0_1531055952421_Screenshot from 2018-07-08 15-17-49.png

mtr from my pfsense box

0_1531055969317_Screenshot from 2018-07-08 15-18-37.png

it's the same...

johnpoz

Not what I asked exactly... I asked if the source IP is the same..

While you might hit the same gateway that .233, maybe your coming from .A when natting your clients behind pfsense but pfsense is using .B as its IP. For example if you have a VIP setup when you have multiple IPs from the ISP..

You only have the 1 public IP, and no vips setup on pfsense where it could be using a different source IP.

Just makes no sense that your not getting any replies to your queries when pfsense does them, but do get replies when client behind pfsense does the query.

juniper

80.19.236.233 is my public router

80.19.236.234 is my pfsense public interface directly connected to 80.19.236.233

ntp internal server is 10.10.11.2 connected to pfsense 10.10.11.1

johnpoz

Well then why does server X not respond to a ntp query when it comes from pfsense, but does respond when it comes from client behind pfsense? That is the million dollar question.

Since the source IP is the same. The clients are the same ntp version it looks like.

ntpd 4.2.8p11@1.3728-o

So I would suggest you set pfsense to use both your local ntp, and public ntp. It will now query both of them. Are you not seeing answers from the public ones? See my output below, you see pfsense syncs to my local stratum 1 ntp server I run. But it also asks pool as backup to if my local goes down (pi with gps as my ntp server). you will notice that they all show reach of 377.. Means talking to them and getting answers..
