This is the virtual servers list in my new router:

Why so many entries for Teredo, including multiple duplicates for same IP numbers? It looks like the list just continues to grow and grow. I'm not sure that I like having so many ports open, also I wonder how many lines can exist before the router starts falling over.
Should I worry?
