SG-3100 Potential DNS issue / Intermittent drop
-
Hello all! New to the forum and the platform. I have thoroughly enjoyed pfsense and the quality device netgate has produced but am stuck on one nagging issue. Resolving websites hangs for 30 seconds to a full minute multiple times per hour and during that time if I attempt to ping google dns it fails but after 20 or 30 attempts all of a sudden comes back. This is happening all day every day. For context, I have ATT Fiber 1G/1G for my ISP and have their gateway setup in IP passthrough mode with all filters and firewall features turned off on that device. Has anybody experienced this issue and can provide insight on a fix?

Do you use Unbound resolver ?
Have you enabled : Register DHCP leases in the DNS Resolver
Don't do that.I did for starters, and chased the same ghost as you see.
Every time a lease is registered , Unbound is restarted , not "HUP'ed".
Creating a "DNS loss" during the restart time.Try to remove any registering , besides static , in the resolver

I'm not sure how to answer whether I use unbound resolver. I do have DNS resolver enabled and took your advice in checking Register DHCP leases. I also disabled IPV6 completely. So far so good.
Thank you for the help! @bingo600

That sort of delay can be introduced if you have partially configured IPv6. If hosts are receiving an IPv6 IP and route but do not actually have IPv6 connectivity they will try v6 first and have to time out.

He meant to uncheck that option...when a lease is registered it will cause unbound to restart. Sounds like that wasn't your issue, but it may crop up if you turn that option on.

I just corrected my post , to say don't enable that.
Could be a bit misleading , if you didn't read the full postThnx
Edit: But i'm quite sure that OP got the meaning of what i wrote , and disabled the registering.

Hello, I did not experience this issue before.This is strange that it happens to you most of the time. Maybe deregister?

@negate1 Pretty sure you're a bot or increasing post count in preparation for spam at this point.
Please clarify your statement here and prove you're not.
