Thanks for the information everyone! Most I will spec out several solutions for them, but the preferred solution will probably be a firewall just because most appliances will do more routing then they would need. I was looking at the Sonicwall NS series because it looks like they provide good throughput for the price. Brielle: Thank you for the info about the Ethernet port on the ONT. I will make sure to relay that information. At this point I believe they would want to make their service stable and worry about maximum bandwidth once that is done. The router they have is the MI424WR, which is what I have for my home service. I don't have many complaints about it at home, however it's clear that it's not up to the task in the case of my client. They have had the router replaced by Verizon 4 times in about as many months. - Chris
