The problem is feeding their router data through my DD-WRT router. An ethernet port is provided which they claim work but provide no information for doing so. They sent a "technician" a few days ago and he knew nothing more about it than I do except he assured me it should work but did not know how to set up both routers, tried what he could for an hour and said if you can't make it work and call for help, tell them to send someone else ...
Seriously? They couldn't do such a simple thing? Such complete incompetance with a so-called tech.
Unless they've done something goofy with their hardware, it should be easily doable just as others have said on here (put your router between their equipment and yours, WAN side of your router facing the service provider). That's a two-minute job.
It's not the ideal situation, but should work without doing anything more than cable patching. And things should continue to work within your LAN the same as it always did.
If you did things like SSH in from the outside world, or accept other incoming connections, then you will strike problems. Their equipment would act as a firewall. That's why people say put it into bridge mode, then it's virtually transparent.
If you wonder whether their ethernet port is working, in itself, just connect one of your computers directly to it, and check.
