Thank you very much for assisting me with this. Again, I really appreciate it
All is well thanks to you guys (and gals of course if there are any)
I added the Ethernet connection to the ONT, called up Verizon, made them switch over, tested with them that it works, then went ahead and connected the ONT Ethernet to my DD-WRT WAN port, and another Ethernet cable from the LAN of my DD-WRT to my Verizon WAN port.
After that, all is well. Thanks again!!
