Oh, another thing related to firewall rules.  Set your rules to log 
everything that is dropped by the firewall.  That way, it is easy to 
check your logs and see that your SSH connections (or whatever) are 
being dropped by the firewall.  Yes, it can make a lot of noise in your 
log file, but that's easy enough to filter out using grep -v.

Remember, you can never have too much information.  You can always 
filter out the extra, but its impossible to add more later.
