Nope… My Surfboard 8611 has that (just Cable<->single ethernet port).
In non-bridge mode, it acts as a NAT router between the ethernet port and the
single address dropped on the modem by the $CABLECO DHCP server.
In bridge mode, it passes my packets to the $CABLECO DHCP server.
Since I have business service, I’m able to use that to actually get DHCP
addresses on multiple devices.
In my case, that’s a pair of MX-240s and an SRX-340.
The SRX-340 provides a backup simple network (SRX LAN ->NAT->$CABLECO) in case
things go wrong with the (usually more reliable multi-homed) network. (This was
quick and easy to set up and helped keep the family off my back while
troubleshooting the transition to the bigger upgrades).
The MX-240s each also have a connection to Ridge Wireless and there are GRE
tunnels from each via Ridge and Comcast to each of:
+ MX-240 at HE FMT2
+ VM/FRR based router at 55 South Market (San Jose)
+ Act USA in Las Vegas
BGP and traffic flow over the tunnels (BGP is loopback to loopback for FMT2 and
55 S Market, direct EBGP peering to Act USA).
