[Xitami] only localhost access for xitami - help

[leegold]

I am using xitami as a testbed for cgi.
It's on my pc. But my pc has dsl. I want to block
any outside access to xitami server, as I said it's
on my pc and I only want to allow access to it from
THAT (my) pc.

Is this a valid concern since I am networked to
the internet via my dsl?

If so what's the best way to do what I want?

note: I have a linksys router between my dsl modem
and pc - I think it has simple firewall capabilities, if
that's any help.

Thanks
