Do not put the source match in the PREROUTING rule (thus your squid access from the local LAN will not break). Do put the source match in the FORWARD rule. That will restrict outside access to only 1.2.3.4. I assume there is already a FORWARD rule that allows access from the LAN. Hope this helps - John -- John A.
