"Cablevision's new Optimum Online business-class cable modem service has technical shortcomings that will frustrate many solution providers, according to CRN Test Center engineers. But there is a workaround."

"Cablevision's nonstandard implementation of TCP/IP routing might cause problems with Linux, Solaris and other operating systems that adhere to TCP/IP stack standards. The Microsoft TCP/IP stack used in Windows 9x/NT overcomes the problem by relying on the Address Resolution Protocol (ARP) to contact gateways on the local subnet."

"To work around these issues, either a Microsoft operating system or a third-party hardware solution must be implemented. The CRN Test Center overcame the NetWare incompatibility by installing a Linksys Etherfast Cable Router. The Linksys received TCP/IP information from Cablevision's DHCP server and provided a static IP address and default Gateway address for the NetWare server."
