After setup wizard WAN gets no IP (connection fails)

xyz12346

Hi there :)

I am new to pfSense and it fails directly

I have a Telekom Speedort Smart 4 standing behind the default DSL connection (no modem) and have it configured as a DSL Modem (simple click in the GUI).
Then the Link1 (blue) RJ45 goes to the Netgate 1100 WAN RJ45. I follow the setup wizard and tried DHCP and PPPoE connection. Both fail!
The WAN connection shoes green, but the interface shows n.a. and no IP
dpinger is not starting showing error 65
I tried:

setting VLAN tag to 7
switching cables
different booting orders for Speedport & Netgate
DHCP & PPPoE connection
resetting Netgate & Speed port

I just cannot find out why it is not working. I tried the logs, but could not find a clue to the cause of this problem.
I can / will add the logs as you need them.

I hope I (we) can make it work.

You should try the default DHCP, it works immediately, as soon as you concoct your pfSense to the upstream router

Or, you have the somewhat more complex 'pppoe' as you have probably an upstream 'modem' device.
The cable between pfSense WAN

For DHCP is just : no wizard, just connect and done.
You can see that for yourself, as you would received a 'lease' (IP, gateway etc) as shown here :

Be ware ( !! ) : if you use 192.168.1.1/24 on your pfSense, and you ghet also a 192.168.1.1/24 you ahve a decision to make

pppoe : first, get the ISP "How to connect / set up your pppoe connection documentation".
Use that to set up your pppoe connection on pfSense.

These is no such thing as 'try something out at random' : the ISP has the info for you, and they decided it will be the hard hard way.
This can help you : as pfSense behaves exacly like a "PC" that you would connect to your modem, how would you set up this PC ? That's the info you need.

Correct.
If no "IP" that ping (actually : everything) won't work.

edit :

Wait :

is this a router or a modem ?

@Gertjan hi :) thanks for the quick response

It is the default router from my ISP. But I switched it into DSL Modem mode in its settings (requires restart etc.) but then only works as a modem.

I tried PPPoE as my ISP requested it, but did not work, same for DHCP.
If I try to "connect to WAN", I get an IPv6 Link Local, but no IPv4. And after I reload the page it says again " connect to WAN"

I configured it now as most people said it should be for my ISP (Telekom) and this router (PPPoE way). But now the WAN connection is completely down.

I can understand that you want to use pppoe as it permits you to have a 'real' "WAN IP" on your pfSense. One main advantage : NAT, if needed, becomes somewhat easier.

pppoe by itself is pretty dead these days as creating maintaining building a pppoe connection needs a lot of system resources, ok for a low end xx Mbits connection, but with fiber these days, like hundreds of Mbits / sec, a pppoe wouldn't make it anymore.

Your router in DHCP mode : don't connect pfSense to it, first, connect a PC. It should connect right away.
Then tell use what (RFC1918) IP, gateway DNS etc it received. ( type ipconfig /all ).
If your PC received an IP in the 192.168.1.0/24 network, you'll have a conflict with your pfSense LAN as it is also 192.168.1.0/24 by default.

You have a choice :
Connect to the ISP Router GUI, and change it's LAN from 192.168.1.x/24 to something like, dono, 192.168.10.1/24 - and check also the DHCP server on that ISP router, modify the DHCP pool to something like 192.168.10.10->192.168.10.250.
Re connect your WAN pfSense to one of the ISP LAN ports, and now it will receive a WAN IP (RFC1918 of course) somewhere from the ISP router's pool. And your connected.

Using pppoe :

It could be as simple as : select "PPPoE" :

and fill in this info :

and done.

But no .... Maybe you have to create a VLAN based upon the WAN port.
Then select pppoe on WAN, etc ...

Your ISP has a name ? Use its name to search here on the forum. Pretty sure some one else is already detailing the how-to-connect process.

@Gertjan connecting from ISP Router LAN to pfSense WAN worked :) thanks.

Is there a downside to that setup (regarding privacy/safety)? Since now also the Router from my ISP is running as a parent.

PS: my ISP router uses 192.168.2.0\24 not the same as pfsense

Where and how are you applying that VLAN?

The router/modem may do it for you.

If you're doing it in pfSense you will need to configure the switch on an 1100.

xyz12346

@stephenw10 what do you mean regarding the vlan? The vlan tag 7? I did it everywhere, under assignments, switch etc.

Currently the setup is:
ISP Router/Modem -> pfsense
And I would now setup pfsense with my custom config for different vlans etc.

stephenw10

If your ISP requires VLAN7 for DSL then it needs to be configured correctly. On the 1100 that means configuring the PPPoE session on mvneta0.7 and passing that tagged through the built-in switch.

But also check if the router/modem is doing that for you in pass-through mode because double tagging would likely also break it.
