[QUOTE="EvenStranger, post: 1252668, member: 181804"] The first thing to understand when dealing with cable modem issues is the difference between external addresses and internal addresses. The best analogy I have been able to come up with regarding the cable modem and router relationship is the standard corporate office. If you look up the phone number for XYZ Corp, you'll find a single number, say 1-800-555-1234. However, once you dial that number, a switchboard can route your call to anyone else inside the building. That's basically how your cable modem and router work. Your ISP provides a single external IP address for your cable modem. Your cable modem connects to your router, in your case your Time Capsule, and your TC serves up alternate internal IP addresses, or extensions if you will, to the rest of your network. Occasionally, a cable modem will also serve as a router, providing it's own internal addresses. In those cases, you can choose to set the TC in Bridged mode, where it doesn't assign new internal addresses, but passes through the addresses provided by the cable modem/router box. [/QUOTE]
