New Unifi modem and no internet on LAN
-
@viragomann Yes. I do have outbound NAT in automatic mode. My gut says that this is a firewall rule issue. I know the modem has an internet connection because I can connect my laptop directly to it and it pulls a DHCP address.
I have my DNS servers set to 1.1.1.1 and 8.8.8.8 . When I do a dns lookup for pfsense.org
Here are a few screenshots:

Are the pfSense WAN and LAN using the same subnet by any chance and hence conflicting?Otherwise post Status > Interfaces, please.
-
@viragomann they are not using the same subnets. When I plug in the connection from the modem to the WAN port on the router it has shown the IP address I am getting from the ISP in the WAN interface status. But in this screenshot it isn't. On the dashboard I have seen it pop up in the gateway field but then it disappears.

Strange. Obviously there is something wrong with the WAN interface.I expect, that there are some hints to see in the log after reconnecting the WAN. Check the System and DHCP log.

Yup not pulling a lease at all has to be an issue with the modem. Is it locked to the laptop MAC? You power cycled it?
Is it actually a 'modem' or a router? Does the laptop pull a public IP from the ISP or something private from the 'modem'?

@stephenw10 The modem is a Unifi UCI. When I plug the laptop into the modem I get a DHCP address that is in the same subnet as the gateway address. I confirmed with the ISP that it does not lock the modem to a specific MAC address for the router.
@viragomann is there anything specific regarding the system and DHCP logs that I should look for?
-
@yaegermeister163 Did you plug a pc into the modem and check?
If you just switched it, some ISP's make you "accept terms" before you get internet. Usually you have to go to a captive portal or similar. Maybe that's it. -
@yaegermeister163
The DHCP log should show, if the DHCP client tries to pull an IP and maybe why it fails.
The system log could show if there are any layer 2 issues.Best to post the section of both after reconnecting the WAN plug.
For analyzing DHCP issues, you can also sniff the DHCP traffic on WAN with the packet capture tool (ports 67 + 68), full details level.

@viragomann I keep seeing WAN_DHCP (ISP IP address): sendto error:65
-
@yaegermeister163
This could be an aftereffect, since the interface IP (+gateway) is gone.
Basically the error means, that pfSense cannot talk to the gateway. -
@Jarhead I have no issues getting to the internet when I plug the computer directly to the modem.

And, to be clear, that's public IP?
-
@stephenw10 Yes, it is a public IP. I have another router and I got that up and running. Going to factory reset the 3100 and start over. Something is buggering it up and I am not sure what it is.

Yes but the modem will limit the number of MACs it will communicate with per power cycle based on the config file that the ISP sends to it. Most residential accounts limit to only one... Some commercial accounts will allow from 2 to 5 from my experience.
You can try cloning the MAC of a device that worked on your pfSense WAN page or simply reboot the modem every time you try a new interface.
