l4 switch -> squid question

If I have a l4 switch (foundry serveriron) directing web requests to my
squid box (port 80), do I still have to run squid on another port like
3128 and use rules like:

/sbin/ipchains -A input -j ACCEPT -i lo
/sbin/ipchains -A input -j ACCEPT -p tcp -d 208.206.76.44 80
/sbin/ipchains -A input -j REDIRECT 3128 -p tcp -s 0.0.0.0/0 -d 0.0.0.0/0 80

or can I just forget the rules, run squid on port 80 and all is well?
