There is little information available via Lucent about the configuration the p25, and what I found in the .pdf was relatively confusing as well. I am trying to get the unit configured for a small 3-5 node home-based network for Internet access using 1-Win2k Advanced Server a Win2k Pro and 2 Win98 machines. I purchased the unit used and have not ruled out that it may be bad. How important is it to use the recommended IP 181.100.100.99 (and the subsequent scheme)? The rest of the network is functioning at 192.168.0.xx Anyone have suggestions or directions to other information that I can use to answer my questions and inevitably the others that will pop-up?
