Damn, thought i might've been onto something then :(

Settings on my Plusnet router:

Yeah if the upstream device is using 192.168.1.254/24 on it's LAN pfSense cannot use it's default IP, 192.168.1.1/24.

Change the pfSense LAN subnet to something else. 192.168.100.1/24 for example.

@stephenw10

I don’t have an option to change settings on my home router.
So because it has claimed 192.168.1.254 that’s what’s caused my issue?

I will try changing it on pfsense when I get home from work.

Yes. 192.168.1.254 and 192.168.1.1 are inside the same /24 subnet. You can't have the same subnet on two interfaces in pfSense (or any router).

@stephenw10

Well.... it’s alive!!!

Switched my lan to 10.10.10.1
I guessed the other settings, I would have consulted some tutorial if I couldn’t wing it.

Appreciate your help Stephen.
Maybe this can be added to an FAQ post made as a sticky topic for us noobs?

Noobs don't read those things ;)

If you think you can have wan and lan on the same network - you shouldn't be touching a router/firewall in the first place to be honest.

That is like the warning on your coffee that says its hot ;)
Do not put your penis in the paper shredder ;)

Is this sort of info really needed to be stated?

@johnpoz

Yes as I wasn't born with a comptia network+ certification.

And neither were you! :)

stephenw10 · Jul 10, 2019, 9:14 PM

I'm not sure, I think @johnpoz may have been certified in the womb!

But, yes, basic info should be documented and it is:
https://docs.netgate.com/pfsense/en/latest/book/config/index.html

If the default LAN subnet conflicts with the WAN subnet, the LAN subnet must be changed before connecting it to the rest of the network.

Also well worth reading is this:
https://docs.netgate.com/pfsense/en/latest/book/network/index.html

Loads of good info there if you are just learning about routers etc.

No all of my info is learned, just like everyone else - my point is its sub 100 level info..

If you understand what an IP address is an and a network and what a router is - how do you think you can have the same network on 2 different interfaces and route between them..

Just like I don't have to tell you not to put your freaking dick in a shredder.. Did you read a doc that told you not to do that - or is is common sense ;)

Or that when you order a "coffee" that its going to be freaking hot.. JFC!! If you are to the point that you have figured out that you want to run your own router distro you should understand that you can not route between 2 networks that are the same..

I am more than happy to explain basic info to you - do you want to start at the basics of what an IP is.. My point was that anyone that has gotten to the level that they have want to run their own routing distro should know these basics - shouldn't have to be spelled out in a FAQ that you can not route between 2 networks that are the same ;)

When you get to kindergarten they expect you to know some basics.. Same should go for when you attempt to download a routing distro and route and firewall with it.. You should know what a firewall does, and what a router does - etc.. They expect you to know your ABCs when you get to kindergarten ;)

Do we need to teach you that B is after A?
