NTP - poor reach after 20 hours

@johnpoz
I enabled the two logging options. here are the last 15 - not sure if 'unreachable' lines are a concern or normal.[2.5.1-RELEASE][admin@pfsense.home]/var/log: cat ntpd.log | tail -15 Apr 16 11:45:37 pfsense ntpd[76193]: Soliciting pool server 142.147.92.5 Apr 16 11:45:41 pfsense ntpd[76193]: 69.89.207.99 101a 8a sys_peer Apr 16 11:45:41 pfsense ntpd[76193]: 45.79.51.42 0014 84 reachable Apr 16 11:46:44 pfsense ntpd[76193]: Soliciting pool server 209.50.63.74 Apr 16 11:47:52 pfsense ntpd[76193]: Soliciting pool server 142.147.92.5 Apr 16 11:49:02 pfsense ntpd[76193]: Soliciting pool server 75.76.123.222 Apr 16 11:49:02 pfsense ntpd[76193]: 75.76.123.222 0011 81 mobilize assoc 33714 Apr 16 11:49:03 pfsense ntpd[76193]: Soliciting pool server 184.105.182.7 Apr 16 11:49:03 pfsense ntpd[76193]: 75.76.123.222 0014 84 reachable Apr 16 11:50:12 pfsense ntpd[76193]: Soliciting pool server 172.86.181.78 Apr 16 11:51:18 pfsense ntpd[76193]: Soliciting pool server 72.14.181.128 Apr 16 11:52:25 pfsense ntpd[76193]: Soliciting pool server 213.32.40.221 Apr 16 11:52:38 pfsense ntpd[76193]: 216.177.181.129 0014 84 reachable Apr 16 11:54:29 pfsense ntpd[76193]: 69.89.207.99 0613 83 unreachable Apr 16 11:55:52 pfsense ntpd[76193]: 45.79.51.42 0013 83 unreachable -
your prob going to want to look at more than the last 15 entries..
But unreachable isn't good no..
You can tell from your reach numbers your having a real hard time getting responses from the ntp your trying to talk too..
Those numbers your showing for reach values are not indicative of good connectivity.. Take your numbers and convert the octal number to a 8 digit binary and you can see response or no response for the last 8 you have sent.. To that specific IP.. When you are seeing the numbers you are seeing.. You have hard time talking to those ntp servers.. Be it they are not getting your query, or they are not just answering.. But those reach numbers are not good for keeping good time..
edit:
Maybe vs using pool, try some specific one that are in your geographic area
https://support.ntp.org/bin/view/Servers/StratumOneTimeServers
https://support.ntp.org/bin/view/Servers/StratumTwoTimeServersThere are plenty of ntp you can specific point to on the net.. You normally want something close as possible to you, to min the delay. But you for sure need something you can reliably talk too..
Add say time.cloudflare.com
They have like 180+ locations via anycast.. You should be able to hopefully talk to something reliable via that..

Those are not working ;)
Your isp blocking ntp?
The only one your talking to at all with a reach of 74?
so 00111100..
-
@johnpoz
how can i determine if isp is blocking ntp? There is some 123 traffic on WAN interface getting blocked - not sure if due to isp.I tried to upload image to make things easier for you to troubleshoot, but received notification "something went wrong while parsing server response netgate"
-
@johnpoz
upload works on diffeerent browser (firefox-yes, brave no-go)

Yeah doesn't sound good.. If that was your return answer from your ntp query..
As to tell if its an isp/internet issue - would sniff on your wan, you would see your ntp queries go out - but never get a response in your sniff. As to that being your isp blocking, or just getting lost in the internet, or the place your trying to talk not answering you - that is the question..
Do you have a vps or something you can fire up, and run ntp server on it - and see if you can talk to that?
If you get a glitch trying to post an image, try again in a few minutes. In the past I have had issues posting images, but try again in few minutes and normally works.
Are you noticing any other issues with your internet connection. Are your states resetting? If your states reset, then yeah return of a ntp query would be blocked because there is no state to allow the traffic back in. Yeah udp is not stateful ;) But pf keeps track of it via a state entry..
edit: Are any of those IPs of NTP servers your trying to talk too?
Doesn't look like it because the source port is not 123.. Looks like they are asking you for ntp.. Do you have your IP listed in the ntp pool or something?

Just looked up the 123.170.x.x's
I doubt they are NTP ansvers
Seems like CN "probes"

-
Yeah if it was him asking the source port would be different... That seems to be quite a few probes ;) Maybe that is causing him some grief in trying to get ntp working?
-
@farmerjohn I think @bingo600 is going to reach out to you via PM with a ntp server you can point too.
I could also have you point directly to my IP, my local ntp server is part of the pool.. This way if know your IP can sniff to see if the queries are even getting to me, etc.
-
Do you have a vps or something you can fire up, and run ntp server on it - and see if you can talk to that?
unfortunately no - only on my LAN, but that probably doesn't count.
Do you have your IP listed in the ntp pool or something?
no, just china and some other unknowns hitting me via 123
Are you noticing any other issues with your internet connection.
One thing I've done recently is enable fq_codel and under general settings / advanced / Firewall & NAT, lowered "TCP Established" to 86400 and "Firewall Optimization" from conservative to normal.
Also setup openvpn on OPT1 and getting a lot of blocked 853 traffic in log, but have not noticed any connectivity issues browsing on openvpn clients.
-
@farmerjohn smart move to use Quad9 DNS, it blocks a lot malicious sites.
-
Those are all out of state blocks.. see the R and Fs those are RST and FIN packets.. Those are what close a session. If the session has already been closed then those would be blocked. etc..
But why are you seeing them on opt1? And your hiding what I assume is your public IP that ends in .37 there? Why would that traffic be inbound to opt1? Is that .37 IP your hiding a rfc1918 address on your internal network?
-
ip that ends in .37 is my public IP.
Why would that traffic be inbound to opt1?
i wish i could answer that.
here is a short sample of tcpdump, I'm terrible at interpreting this, but posted here in case something obvious.

OPT1 is what interface? And why would the source of the traffic "into" opt1 be your public IP? That makes ZERO sense..
How would you be seeing inbound traffic into a lan side interface with your public IP On it???
I don't even see how that would be possible???
-
@farmerjohn Things are not always what they seem. It doesn't mean that China hits on you, it could be some bad actors who work at your local bank or organization and use China's network. Johnpoz is right, it's very strange inbound connections on OPT1.
Just a suggestion, you could make a new outbound floating rules with selected all interfaces and blocks China networks. In your case, make two aliases, one for ChinaNet and the other ChinaUnicorn. After that see firewall log, which interfaces are blocked.

Zero reason to block those - they are already blocked by the default block rule on the wan. The only reason you would block is to not log them.
Or if you had port forwards, and you didn't want specific IPs to hit your port forwards.
I think there is something really odd with your setup... I just don't see how some opt1 interface, or any interface at all really would ever see your own IP as inbound traffic for a block.. Makes zero sense..
Even if you had 2 wan interfaces, and opt1 was another wan interface.. Why would wan 1 send traffic to wan2 with destination other than your wan2 IP, etc..
How about you draw up how you have everything connected. And exactly what is this opt1 interface? What IP do you have on it? Just at a complete loss to how you would see such traffic..
Normally you have say this
internet -- wan (pfsense) lan/optX -- your networks(s)
How could you ever see traffic from your wan IP, hitting your lan side interfaces, or really any other interface even a wan?? If if you had your wan and lan on the same L2 network.. Why would your wan be sending traffic to your opt1 mac address? Just at a loss to how you are seeing such traffic..
edit?
Also setup openvpn on OPT1
Huh?? Still at a loss to how you would see source traffic of your external IP? Opt1 is setup as vpn client interface? Lets take a look at the details of exactly how your setup.. And if you have some vpn client setup... Turn all that off! Atleast while trying to figure out why your ntp is show sporadic in getting responses. We can always walk through how to correctly setup some vpn client after you fix your original ntp issue.

@johnpoz
em0 - WAN
em1 - LAN
ovpnc4 (vpn provider) - OPT1. i have a few clients on LAN that use this as gateway.
-
Turn all that off!
ok - disabled 1. VPN / client / my provider and 2. the LAN rule for OPT1 gateway (vpn_clients alias).
The NTP status seems to have suddenly improved after just 10 minutes. looks like will be all 377's in a few minutes! so what did I do wrong with my vpn client setup?
