Best CM for dynamic IPv4 and static IPv6
We have an SMCD3G, no longer receiving IPv6 configuration.
We also have a static IPv4 /29. When we were getting IPv6 addressing, I had attempted (unsuccessfully) to get it working/routing with our endpoints and Mikrotik RB1100AHX2. We are ready to drop static IPv4 but want static IPv6. We have a few subnets and would like the option of using EUI-64 for "internal" addressing. We would like to eventually replace our PSTN trunks with SIP trunks. To get/use more than one /64, I think we need to have the SMCD3G replaced with a Netgear CG3000DCR? I noted some VoIP-related posts about the CG3000DCR that didn't look promising. Given all this, what are our best CM options?
