Remote Support Software by techrepublic.

I know I could download the trial software and muck around trying to test the software ability to perform its task. But I do not want to be faced with a diabolical situation of having to reconfigure my modem IP addresses etc. To find out that it falls short of its capabilities. So can you tell me simply. Does the software on installation require me to reconfigure my DSL Broadband modem configuration? Likewise what is required for my remote clients modem configurations? Does it support modems configured with DHCP? How much post setup is required to actual make everything run smoothly.
