[Captive portal] Can't get to the login page.

[wizencrowd]

Thanks for the fast reply

The ethernet adapter virtualbox thing is just a virtual network card from Virtualbox, it is from an virtual machine.

I changed my lan domain to lan.mylocal, do I need to change it in my DNS resolver settings too? Or is there no point of using the resolver.

here is the screenshot ( I don't know how top copy it)

WAN settings ? ("Block private networks and loopback addresses" checked, or not ?)

Btw : how do you connect to the console ?

[wizencrowd]

Block private networks and loopback addresses is checked.

The pfsense is installed on a server, on the server I connected a monitor and keyboard.

@wizencrowd:

Block private networks and loopback addresses is checked.

You agree with me that your WAN IP  (192.168.5.10/24, probably obtained by an upstream router) IS a "private network IP" ?
Better remove that check, your WAN is using a private network.

[wizencrowd]

Ok, I unchecked that. But now I don't know what's wrong… I'm still not getting redirected to the login page. I Can't make an other interface because I don't have an extra network port. So do I need the resolver or not?

Neither do I.

What you should know :
Install a clean pfSEnse.
Accept the default for LAN.
Assign WAN and set it up. Check connectivity to the Internet. (and yes, by default pfSense expects a WAN IP on the WAN interface, a private IP form an upstream router could work,, but … see above)
Add a "captive portal user" in the Local pfSense user manager.
Activate the portal - on LAN should work (the default LAN firewall rule is ok).

At this stadium, the captive portal works.
Your system : it isn't ok.

The question is : what more did you change ?

@wizencrowd:

I Can't make an other interface because I don't have an extra network port.

There is no rush, but keep in mind setting up and exploitation a captive portal (untrusted network) will be easier with a dedicated interface.
Its always advisable to start with easy things, and complicate live afterwards when the basic are understood  ;)

@wizencrowd:

So do I need the resolver or not?

pfSEnse - and you network need a DNS that works.
The default Resolver is just fine.
For some (special ?) scenarios the Forwarder is needed - like - example - for those who want to communicate all DNS traffic to OpenDNS.

Hello

After a Long time I started working on it again. But I found something strange… I took the server to my home and the captive portal worked perfect there. I got instantly the login page when I connect with the server just like you described. But when I'm doing it now at school it doesn't work. I have the exact same programs and browser... It is so weird. The only way I can get to the login page is with a URL like Google.com. At home it works perfect...

And idea where the problem could be? I thought it was maybe my dns resolver?


[Gertjan]

Images/settings look fine.

Can you post your LAN firewall rules ?

When a router/firewall works fine at one place (home) and not good elsewhere (work, school) you have a 99 % that settings should be adapted for upstream routers, ISP awkward issues or other 'special' (read : not 'normal') issues.

Btw - not realted, but : why choosing 192.168.1.100 as a gateway IP - in the middle of the range ?
What's wrong with 192.168.1.1 or 192.168.1.254 if you have to. Leaving everything from start (.1) to end (.253) when /24 for the DHCP pool and static devices.

[wizencrowd]

I took a screenshot from the firewall Rules. I never changed something there so maybe that is the problem.

I took that as default gateway because 192.168.1.1 is the default gateway. But I'll change it to 192.168.1.254. Thanks for the note!


[wizencrowd]

I don't know that this is the porblem but I noticed it. Does the DNS field need to be empty? (Screenshot attached)

I did an Ipconfig /all in cmd and is the DNS normal? Shoudln't it be 192.168.1.100.?

Exact, no need to fill that field.

Don't need to check the next field neither : "DNS Server Override". For a solid, secure DNS functionality you could use what Internet is offering since the day it was born : use the root DNS **.
pfSense uses a Resolver out of the box. Keep it that way.

** except, of course, if your ISP wants you to use its DNS servers (and blocks all other "port 53 request" to other destination) then you are out of luck. Consider ditching the ISP.

Is this A problem?
