Dns stopped working this morning?
-
So works for awhile, and then just stops - ie its working now.
You know since your behind a nat router, could it be some form of flood protection? Ie your "modem" sees a bunch of traffic outbound on 53 all at the same time or specific number within certain time frame all from the same IP (your routers wan IP) so it blocks that IP from sending any more traffic to that port?
I have seen this before with some routers and p2p causing a spike in DNS traffic, and then nothing works because user can no longer do dns.
Whats the specific "modem" you have so can lookup its manual to see if its got some kind of feature like that.
Are you running anything that would cause spikes in your dns traffic? I know for sure that p2p can cause a huge amount of PTR traffic, depending on the client.
-
I don't do anything really DNS query heavy, no p2p. Browsing forums sometimes leads to a real storm of queries though (inline images, etc). Good idea to check for that!
At the moment I have a Thomson TWG 870 - and behold, there is a flood protection on the "Web Filter" subpage. I turned it off, crossing fingers now!
-
well been a few hours since your post – did that fix it?
-
Couldn't really do much testing til now, but it seems that fixed it!
Many thanks!

Well thats is good news.. Looks like nothing wrong with unbound after all ;) heheh
Not a fan of most of these soho routers at all, to be honest if I were you I would really push to just get a standard cable modem.. Can't you just buy your own?
I just bought a SB6120 about a year ago when they came out - comcast had not updated mine in years, and was still docsis 2. And they were charging me rent on thing every month. So vs asking them to update it, I just bought my own and prob already paid for itself vs the per month rent.
I just had my son by one as well vs comcast providing it - they were going to charge him $7 a month rent.. WTF, you can just buy a SB6120 for like $70, less then a year its paid for itself, etc.
Why will they not let you put it into just bridge mode so its not doing nat, to be honest that makes no freaking sense - what does the ISP care if your box has the public IP or their device does??
-
I'm definitely going to ask for the modem next week - the combo modem/gateway just sucks.
Unfortunately we can't just supply our own cable modems, the provider has to have access to the 'cable part' of it to configure their own settings which aren't changeable by us customers. That's life over the pond for you. ;)
And you were right, no problem with unbound at all! :D
-
Just because you buy the modem does not mean your provider does not have access to it.. Once you register it on their network they have access.. So do they charge you rent for the device?
-
No, they don't charge anything extra at all.

hi… i had a same problem before, try putting a dns ip at dns entry in DHCP server (pfsense). may be your LAN client lost auto dns during pc restarted, hope this help.
-
The issue was resolved quite some time ago, and it was flood type protection on his router in front of the pfsense box.. It helps to read a thread before posting in it ;)
