There were a few functions that were not operating as well as I had hoped in the home network now that we have DSL and Cable again and two VOIP telephone lines, one configured per incoming service.
Since we have double NAT which is generally a bad thing, I needed a work around to fix NTP time updates that had broken. This did the trick on the main router (downstream of the modem/routers). Note that I’ve added this to the Connection Hub (DSL Modem/Router) as well.
And while on the subject of router tricks, this port forwarding scheme was suggested by TekSavvy to keep the VOIP Adapter working well on a SageMCom wired port.
