If your firewall is well-behaved, no. There is nothing else to do. 
However, this is not usually the case.  :-(

If your firewall drops idle connections after some time, you will need 
to tune a couple of settings.

In Apache (, set:


In your sysctl settings for the Apache machine, set your tcp keepalive 
time to a value lower than the drop time of your firewall.

Otherwise, you will bang your head against a wall. And that causes 
headache ;-)
