@ahole4sure said in ATT Internet AIr:
The current trouble I am having is that my identical ATT device, when connected to port 2 of the switch, is not passing through the IP address when I created or setup the interface as DHCP -- the other ATT device when connected directly to one of the pfsense interfaces pushed through ATT static publc IP address. And if I try to set the IP address manually it doesn't behave correctly- says offline
Looking at your picture, I see WAN, LAN and WAN2. So what is it that you are trying to do with the ATT modem now, connecting it to the fourth port? Are you trying to add a third WAN?
I don't understand the direction... If your VLAN is set up on pfsense, you make port 1 a TRUNK port as you said, but that means TAGGED 10. And the ports for any devices that should only belong to VLAN 10 need to be untagged and only members of VLAN 10. Currently all ports are also members of VLAN 1...
If you are trying to get an IP on port 4 on pfsense (igb3) from the ATT modem, you can simply make both ports 1 and 2 VLAN 10 UNTAGGED on the switch. Remove them from any other VLAN memberships.
This way you have created a "switch within the switch", where port 1 and 2 are connected but separate from the other ports. Pfsense doesn't need to know of any VLAN on igb3 for this to work...
