Has anyone ever seen any issues at all with Sonicwall Routers behind cable modems after changing from any other CMTS into an Arris C4c CMTS?
What sort of problems are you seeing ?
About the only router-related issue I have seen relates to devices that fail to communicate within the same CPE subnet
ie. customer 1 with CPE IP x.x.x.1/24 cannot talk to customer 2 with CPE IP x.x.x.2/24.
And this is caused overly enthusiastic "ARP spoofing protection" type features in the router.
