I have just joined Plusnet Fibre and I am having problems connecting my PFsense box to the network.....
I am connecting my PFsense box directly into the open reach modem and connecting through PPPoe all appears fine connection connected first time.....
This was an existing PFsense setup and was running fine until moving to Plusnet. I noticed that Outlook was not downloading emails correctly some of the images were not downloading, looking further into the system and I noticed that Windows update had started to fail to search for updates... In fact upon checking all programs that need to check for updates were failing, also Skype was not connecting properly to its homepage and people were showing as offline when they were online.....
All other tasks like web browsing, downloading are working fine.....
I have looked for hours to try and find this problem and cannot see what is causing it, I have resorted to doing a complete new install of PFsense disabling the firewall and turning off all windows firewalls and defender and still have the same problem......
If there is anyone here that has had the same problem or in fact just got PFsense to work ok through a PPPoe connection please share your comments

It's WAN port is connected using PPPoE via ethernet into a bridged (PPPoE<->PPPoA) ADSL modem, and have found it amazingly stable and free from the problems you are describing.
The ONLY hiccup is that the installed 'squid3' caching proxy very occasionally doesn't start cleanly after a pfSense restart following mains power cuts - but that has been solved by powering the router via a UPS.
Do you see any clues in the "System Log" ?

I just have it connected through the bt openreach modem, my old systems WAN was connected through DHCP with a bridged modem. I am wondering if the problem lies with something I have not done with the PPPoe connection. All that I could see that was needed to do was enter username/password into the settings?
I spent 40 mins yesterday with a very patient support guy that confirmed that the network was okay....
I take it that your not on fibre being as you use an adsl modem?

I wouldn't have thought it makes any difference to pfSense whether the WAN ethernet modem is ADSL or fibre.
I use pfSense with 'squid3' to improve the apparent speed of my network by caching the broadband to an SSD.
Is your FTTC modem on a different network subnet to the address that you have pfSense set as ?
as your new FTTC modem network subnet may be different from your previous modem's subnet, and could cause routing problems if it is now the same as your router.
Have you tried setting the DNS to Google and/or OpenDNS in the "System"->"General Setup" section ?

I would advise setting that firewall to 'Low' or one of the Advanced Setting options, but having it on 'High' causes Windows problems with things like updating the time !.

The subnet mask IPv4 on the WAN interface is 255.255.255.255 but my LAN subnet is 255.255.255.0 /24 I don't know if that's the cause of the problem.
I un-installed Squid3 when I started to see this problem, I don't know if I will re install it on this new connection as its fast enough at 73 - 74mb. I mainly use Snort as I have a lot of ports open running a webserver and other things
I'm running it off an old 2.5 hard drive at the moment I was looking at changing it to an ssd drive like you but also wondering if I would be just as good to use an old 32gb memory stick? The hardwares a small format dual core HP desktop that I have taken apart and screwed the motherboad and bits onto the workshop wall, it looks really cool...
Oh and I'm using the 2.1-RELEASE (amd64)

Ahh now that sounds like it could be the cause....
Thanks I will go there now and give it a try

For example, if your modem address is typically 192.168.0.1 or 192.168.1.1, is your pfSense router on say 192.168.100.1, and your LAN on 192.168.100.xxx
You could run from a memory stick, but you would want to use the alternative embedded version, as that is optimized to minimize the number of write operations, as flash memory has limited write cycles and very poor write speeds.
If you are unlikely to reinstall squid (as I agree the effect of caching is reduced with fibre) then stick with your HDD, but if you do want high speed caching, then a cheap SSD or a couple of WD1600BEKT or WD1600BEKX drives in RAID-0 would be better.

Yes raid on a PFsense box would be cool, especially with ZFS

Quote from: Tropheus I'm using the BT openreach modem and have no idea what settings that uses
If you navigate pfSense to "Diagnostics" -> "Routes"
you should be able to see the /24 subnets assigned to your WAN and LAN connections,
also the address that the modem DHCP assigned to the WAN port of your pfSense router.

I have turned off the Plusnet Firewall and that did not help, and added 2 Google DNS in the Gen setup like you suggested, It briefly worked after doing this but then stopped again shortly after.I cant help thinking that there is a DNS problem somewere.
