I wish you didn't.

Google thus:

The answer is in the first document on _my_ list.

Part of the answer is to have a rule that accepts connexions to your box 
before you deal with those going elsewhere.

I don't suppose your DNAT rule is wrong, but it's not what is usually 
recommended, and usual practice is to have squid listening on its 
default port, 3128. I suspect the usual iptables rule doesn't cause the 
conflict you see.
