I was chatting with Marina today (you know M of the M&M's of www.smallbizserver.net and all that) and she had a client using software from www.netop.com for remote control…and the vendor indicates that the software requires inbound port 80. And the two of us are like … excuse me? We both think it's like gotomypc and probably sends out a beacon signal that you can then tunnel back in on. Fortunately she has clients who know her style and trust her judgement and when the vendor said "inbound port 80", her client said "I don't think Marina will like that" and called her.
I too have had a vendor tell me "inbound 80" and I had to go up three levels of support until I found someone who said.. "uh…no, just outbound".
When a vendor tells you something that you just don't feel is right…question them.
Things like "guaranteed 100% uptime"…. okay you don't install patches and reboot then do you?
Things like "inbound port 80"…. you running a web site?
Things like "hipaa compliant"…. ask Alun about that one….
Bottom line… when things don't sound right… ask.
