Verizon loans you the Actiontec router when they come over to install the FIOS service at your home. It is an excellent router in all respects except for one flaw. The router contains a very small (1K) NAT table which can quickly get full if there is a sufficient number of simultaneous connections and cause your Internet to choke for a few minutes.
Fortunately, there is a way to “bypass” the Actiontec router by turning it into a network bridge to your wireless home router (such as D-link or Linksys) and directly use your router for the Internet connection. The tricky part is that you still need the Actiontec router in this picture because it is responsible to communicate the TV channels guide/schedule to your DVRs.
The short summary of the solution is to create two bridges and use DHCP relay:
Create a bridge from Broadband Connection(Coax) to Home Network (your router which will get the pubic IP from Verizon and is the DHCP Server for the network, including the DVRs)
Create a bridge from Broadband Ethernet to Coax and set it up to use DHCP relay (so your router can assign IP addresses to the DVRs and enable them to download the Guide information).
Below are the step-by-step instructions (taken from this link).
Configuration of your cables and the secondary router (D-link or Linksys).
Coax -> Actiontec -> Actiontec:Ethernet connection1 -> 2ND Router Internet Port (WAN Connection)
2ND Router:Ethernet port 1 -> Actiontec:WAN (Internet)ethernet port.
Sounds redundant but your second router is the new DHCP server and the Actiontec uses the DHCP server to give itself an internal ip address and allow Internet connection for your DVRs.
