Although "Stealth" is preferred, "Closed" is acceptable, since
they are still, well.......closed. ;-) But depending on the
security of the PC, they could become opened at inopportune
times.
It's a router (a decent one with a hardware firewall) that will
usually give you "Stealth" at all the ports. The last two
routers I've used got a Stealth rating across the board even
with my software firewalls disabled. So I'd get them to use a
router, or a better one if they're already using one. Or like
Phil said it may just be settings. But using a decent router
doesn't just give more security, you never have to log onto
your ISP to get online.
RPC has to be open on some PC's since it controls a lot of
things that may be installed or enabled on a PC. But 'RPC
Locator' could possibly be set to "Manual" depending on their
PC. It could be the XP firewall "knows" that the PC may not
need RPC open as per the PC's settings, and Comodo may think it
does need to be open.

Hello listers,
I was at my in-laws house this past weekend and ran the Shields
Up! test
on their computers, https://www.grc.com/x/ne.dll?bh0bkyd2. They
have XP
pro on all 3 with only the Windows firewall running and the NAT
on the
router running.
Each computer failed the test with most ports being reported as
closed
rather than stealthed like they should be. So I turned off my
Comodo
firewall and turned on the XP firewall and only the ping made
it
through, then I turned off the windows firewall and tested the
Comodo
firewall. Upon running the test on the Comodo firewall it left
the RPC
open. Strange.
So I tried the test on Linux and Mac and they both let ping
through but
stealthed everything else exactly like the XP firewall. Both
Linux and
Mac filter outbound transmissions unlike the XP firewall but
all 3
performed better than Comodo, if only slightly.
