ipfw rules for letting ssh requests in

[Andrew L. Gould]

I can't seem to get the ipfw rules right for letting ssh clients access a ssh 
server.  I can use ssh on the server to connect to the client; but if I try 
to connect from the client to the server, the operation times out.

I have my rules in /etc/ipfw.rules.  Executing 'ipfw show' displays all of the 
rules as expected.  It also shows packets having been allowed at rule 300 
after an attempt to connect has been made.

I have copied the top portion of /etc/ipfw.rules:

#!/bin/sh

# Andrew L. Gould's firewall rules.

fwcmd="/sbin/ipfw -q"
${fwcmd} -f flush


# Basic rules that should not be changed
${fwcmd} add 00100 pass all from any to any via lo0
${fwcmd} add 00110 deny all from any to 127.0.0.0/8
${fwcmd} add 00120 deny ip from 127.0.0.0/8 to any


# Allow specified service requests in
# ssh
${fwcmd} add 00300 allow tcp from any to me 22
${fwcmd} add 00301 allow udp from any to me 22

Does anyone have any idea why the operation is timing out or what I have done 
wrong?

Thanks,
