There are still some knobs…
e.g. bridge mode or not (usually)
I'm guessing that's only if there's a built-in wifi router. My grand experience with cable modems counts to exactly two brands and four models, but in each case the model without wifi was solely a bridge. The knobs, as such, were: change the password and reboot the modem.
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).
