Windows Clients cannot access the internet, very strange unexpected DNS problem.
-
@johnpoz Poor lord , it didn't expect it to work, yes indeed it became a square after the reboot of windows and pfsense.
I thinkt it was the NAT rule and changed it to automatic like you mentioned. -
@bmeeks It's working, the only thing i changed was from outbound to automatic, done a reboot of windows and then things started to pop up,...
Many thanks to you, and God bless America, from Belgium,..
Clever guys you Americans.

That NAT rule was definitely suspect! Not sure why a handbook for the DSL modem would suggest that UNLESS the instructions were simply how to access an internal web GUI on the modem itself. But those instructions would not apply to general Internet access.

We can both be members of that club as well.. The old farts club, and sometime confuse threads club.. Maybe getting old and confusing threads go hand in hand? ;)

@bmeeks I don't know where I got it from that MODEM config think, I think the handbook, not sure

I resemble both of those remarks

That particular NAT may have been to allow access from the LAN side of pfSense to a web GUI inside the modem that has a private RFC1918 address. That would possibly explain the 172.16.0.x destination address. But to get to the Internet, the destination has to be * (which means "any").
-
@bmeeks Of course, that was it, it was meant to access the modem.

I think you understand, but just to be sure and to help someone else who stumbles across this thread in the future --
That NAT rule was to allow you to open something directly on the modem itself. Typically this is some type of configuration program either via an internal web server or maybe Telnet. So, if the modem had the IP 172.16.0.1 as its LAN port address, then from a client on the LAN side of pfSense you could open a connection to that IP and the NAT rule from the handbook would have translated that traffic to the modem's address. But that rule only works for talking to the modem's OS. It is not sufficient to send traffic from the pfSense LAN side out to the Internet.
You don't need to access the modem in order to send traffic to the Internet. When in bridged mode everything that comes in on the modem's LAN port is sent straight out the modem's WAN port without any change -- and vice-versa for WAN to LAN traffic on the modem. That is the definition of "bridged".
As for NAT rules on pfSense, you need a NAT rule that accepts traffic from whatever networks are behind pfSense and translates them to the pfSense WAN address. The "destination" for this NAT rule should be "any" because that covers the range of possible Internet destinations.

Yes, you are completely correct, I was confused, and yes classically the modem is accessed via webbrowser, now I get the concept of bridge modus better.
My sincere thank you! -

My sincere thank you!Glad it's all working now. Must be quite late for you in Belgium! Go to bed now and celebrate success tomorrow.

@johnpoz Hey Jhonpoz, thank your for the time you put in my thread and the commitment (fast replies)
Chapeau! -
@IrixOS your more than welcome - glad you got it sorted.
-
@johnpoz Hmm JohnPoz, you are never gonna believe this. DNS lost its grip, yesterday and the day before. Rebooted twice.
The bottom right task square turned into the world icon. Couldn't connect to any webpage, DNS server unavailable, don't know what caused it. Didn't do troubleshoot either.I don't mind rebooting the firewall once in a while, but if the website comes online with other future stuff, then I'm beginning to worry...
-
@IrixOS you should never have to reboot the firewalll, unless your updating it to be honest..
My pfsense has been up 82 Days 14 Hours 23 Minutes 31 Seconds, and I even had a power outage - but it wasn't long enough that my ups couldn't cover it.
Pfsense rebooted when I updated to 23.09.1, which came out 85 days ago, so I was a couple days behind when it dropped ;) when I got around to doing the update..
If you have an issue with anything - the last thing I would do is reboot pfsense, after you have gathered info and not able to recover by any other means.. If you just rebooted and it then works you have no clue to what was the actual cause.. A reboot of pfsense should be your last thing you do, or if you can not access it at all - not via gui, not via ssh, and also console.. You want info of what is going on before you just reboot something..
-
Well I totally agree with that.
The firewall seems to be unresponsive. Didn't touch anything since the last time we have been troubleshooting.
I don't expect you to go through all the troubleshooting again . The dns server doesn't query.
Frankly I don't know what to think about it right now. It shouldn't behave like that.
-
@IrixOS your on the gui - sure seems like its responsive to me..
Did you try just restarting unbound? do you have internet access even? can you ping 8.8.8.8 from pfsense?
I would have to read over this whole thread to recall what was going on... I can not remember if you have pfsense set up to forward or not.. If its default resolving, then do a dig bing.com +trace so you could see where pfsense is failing in the resolve process.

@johnpoz Did you mention time like time settings?
I got this mini firewall with pfsense+ already installed from china.
When inspecting the device, I noticed the BIOS time was wrong. Doesn't matter which save option you choose from the menu, it still does not retain the time setting.
I contacted their support and there was some woman pulling tricks to me and said that the time has to be changed to the Chinese time schedule.Excuse me
?What I did was change the date with the BSD CLI in pfsense, but that was yesterday.
