Please help with WAN configuration

Balanga

I can ping the modem from the pfSense router and I can access the web configurator from my laptop, but can't seem to get Internet access… Seems as though I can't stumble upon getting the gateway configured properly.

I can ping the modem from my laptop so routing from laptop via router to modem works but there is no access beyond the modem.

Have I blocked access to the Internet from within pfSense unwittingly?

Do I need to specify the external IP address of the modem somewhere?

Sorry for all the questions but I don't seem to be making much progress.

Thanks for the pointer, but I have a very basic problem…


Check that the WAN IP address is correct (Interfaces > WAN)
- Using the wrong address could cause a failure of the ISP to deliver traffic to/from the firewall, among other issues

I'm not really sure what to set the WAN IP address to. If I set the type to DHCP should I expect the modem to provide an address? I tried that but got 0.0.0.0.

I have noticed that when using my LINKSYS router the WAN IP is set 92.239.173.103. This gets set automatically by DD-WRT. Should I expect something like this with pfSense?

Absolutely, yes!

How was your Linksys device's WAN interface set up? DHCP or PPPoE or … ?
Set the same in pfSense and it should work as well.

BTW: Since 92.239... is a public IP your modem seems to be in bridge mode, passing the WAN traffic to your router. That's the preferred way of doing it.

Dude reset your modem (power cycle) when you connect a new device with different mac.

If your old router was dhcp, then pfsense would be dhcp.. But you almost ALWAYS need to power cycle a cable modem when you change the device connected to it.

Set pfsense wan to dhcp. Power cycle your modem and then reboot pfsense - do you get an IP?

Thanks for all the suggestions everyone made.

I do have my pfSense router working now, but the problem stemmed from the Virgin Media Superhub not providing an IP address initially. I rebooted countless times and wasn't sure how things were supposed to work.

Thanks to some advice I received elsewhere I put the VM hub back into router mode, connected up my cables ensuring that the cable from the WAN NIC was connected to port 1 on the hub and re-enabled modem mode. This time the WAN IP address was immediately assigned when the hub rebooted.

So now I am at the start of my voyage of discovery with pfSense :)

"immediately assigned when the hub rebooted."

Yeah the power cycle when you went to back to router mode vs modem mode is prob what did it..

Balanga

I don't think so since I power cycled about a dozen times. I think it was something to do with the WAN IP address had already been assigned to my LINKSYS router when I first went into modem mode.
