Do I need to filter multicast signals?

[picard]

I have questions about filtering data coming through router.

Do I need to filter multicast signals, port 113, and anonymous internet requests?

I have the Linksys WRT54G wireless router.

What is multicast signal?

what is port 113?

Is anonymous request similar to FTP login?
