Every once in a while I see traffic on my DSL modem. To my knowledge nothing is being up or downloaded. Is there any way of monitoring what or who is communicating with my computer?

are looking for updates.

You could open a cmd window and type -
netstat -an

This will return a list with all your connections. You may then use a site to do an IP lookup.

it is probably normal, as DHCP causes much ARPing.

Another alternative to check what any particular computer may be doing is to run Wireshark on it. http://www.wireshark.org/

But all sorts of applications, including the operating system, check things over the internet all the time for updates and whatever. Are your system clocks set to stay updated over the internet? That'll do it too. Some modems and routers do it a lot as well, doing DNS lookups on a the vendor's domain for some weird diagnostic reason. If it was provided by your ISP, this is even more likely to occur.
