I have a TBR140 with a 4G sim card that is connected direct to the WAN port of my Pfsense router.
When I went to the Network Interface of my TRB140 I found 3 interface! I expected to see only 2 interface. The 4G modem and the LAN.
Because my Pfsense router is taking care of the firewall, VPN, NAT, etc,etc..... What is the best setup that I should use without slow down the internet connection and avoid double NAT?
