Hi, I was wondering if anyone could help

We have a Draytek 3300 and around 40 PC's in the office, when I view the web configurator page and the data flow monitor under diagnostic tools, my Ip address shows I have 100's of 'sessions' compared to 2/3/4/ of all the other PCs

Why would this be? it is not a one off this is daily.

Thanks

James..
