can’t open port 53 tcp and 443 tcp on pix even with acls

Hello all,
i faced a situation and that is: even i open ports tcp53 and tcp443 on my pix using access-lists, after i scan ports on the server from internal or outside, the ports are closed and only certain ports are open. my server is on dmz and i want to open the ports for outside and inside
i already opened other ports such as smtp and www for my server but only 443,53 are not opening with the usual way. i guess this is somehow related to inspection rules; does anybody khnow a way to do this?
