Please forgive me if this is just a brutally naive question. My network knowledge is primitive at best. My setup is as follows. I have AT&T DSL with a 2Wire router in my home office. I have it going through the home's powerlines to a switch upstairs. The line then gets distributed to all the various elements of my home entertainment system. There are also two HR24s, linked through DECA and connected to my network via ICK. Following problems with the receivers losing each other and MRV malfunctioning, the nice folks here talked me through setting up static IPs. That totally resolved the problem and it has worked superbly since then. However, I wondered whether that would open up my home network to security risks. Isn't it the case that the whole idea of dynamic assignment of IPs would prevent an outside attacker from continually going after a static IP? Or, am I must grossly misunderstanding the entire process (because, as a i said, I'm in nOOb city).
