My router/firewall blocks all ports, including those over 1023 (1024?)

I assume you mean that your router *can*, not that it
necessarily does. It seems like it would be awfully
inconvenient to block all such ports, given that programs
often need to open connections to non-privileged ports.
E.g., see below for all the ports that netstat reveals have
connections currently open.


Sorry, maybe I phrased myself badly.

I, and I think the original poster is in the same situation, have my
own box behind a separate router, that router is firewalling incoming
traffic (WAN -> Me) and in my case then it does block *all* ports except
ones specifically allowed by the router admin (in this case, me).

My setup is similar. I have a router with only one computer on the
LAN side, and one ADSL modem on the WAN side. I have mine stealth
on all ports except the e-mail challenge port, which is closed.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
