Bridge Mode and Static IP

Before Comcast reads this and goes to reply PLEASE I already know with your system with a modem in bridge mode static IP is not possible on a device behind the modem. I'm making this post to talk with other Comcast business customers to see if they have a solution to this horrendous system I'm stuck using. Also yes pass through mode is the only option but pass through mode is still behind NAT.


Customers: Is there ANYONE on here that has gotten their business cisco modem AIO in bridge mode and their static IP working. I talked with a tier 2 tech and he informed me the static IP routing is RIP with auth key ( which is programmed into the modem software itself obviously. The tech told me he had one customer who did get it working but she refused to tell him, probably think she'd get in trouble or something.


Has anyone gotten bridge mode AND static IP functionality to work with a device behind the modem. It doesn't matter what device or vendor at this point I just need some real world configs to go off of.


Figured it is worth asking before I start looking into trying to get raw data at the coax level to see what the docsis frames look like and see if any info is usable related to the way static IP is negotiated to the modem.
