depending on how your configuration is in XPE... you can use the Network
configuration, under TCP/IP, and setup TCP/IP filtering, to permit all,
permit only on TCP/UDP, and IP ports. You can then tell it to permit only 21
and 80, and it should work for you.
The only real ports I see a potentail problem with is 13 <Daytime> this is
commonly used in fingerprinting operations... and 22, which is ssh, and
PCanywhere. (that one could be a problem :-) )
Again, Not sure how your image is configured app wise, so it's hard to
say... you could always implement a more stringent firewall in your system,
such as blackICE or checkpoint, but that's up to you.
