How do I port forward my cisco dpc 2100 r2 modem? (is it a router?)
Computer OS: Windows XP
down loading software that came w/ equipment that requires port forwarding, but this model wasn't listed.
The Cisco DPC2100r2 is a cable modem not a router. A modem strictly provides the connection, it has no routing capabilities as far as port forwarding.Thank you for using JustAnswer!
