Port scanning

[jayclark]

Hi all, I have somebody scanning my ports about three times daily. In about 2 minute intervals. The ports that are scanned are 6129, 3127, 1025 and 2745, 80. What are these ports used for? When I do a back trace it goes through 17 hops and ends up at the IP address of 69.70.139.2 the name is modemcable002.139-70-69.mc.videotron.ca. The whois info is

Le Groupe Videotron Ltee VL-13BL (NET-69-70-0-0-1)
69.70.0.0 - 69.70.255.255
Videotron Ltee VL-D-MR-45468B00 (NET-69-70-139-0-1)
69.70.139.0 - 69.70.139.255

What or who is scanning my ports? I am using Sygate Personal Firewall. While typing this I got an alert saying
