Hi everyone,
 I Just got a PIX 501 for my company and since they have strict policies i
do have to strict usage to port 80, now with the PDM i try permiting
outgoing traffic from the my local net on port 80 to any outside port and
permit outgoing traffic on port 53 for the DNS to any port since we use the
DNS server of our ISP. the only thing that happens is that i still can't
resolve websites and they only work if i use their IP addresses. i do use
PAT and i'm not sure wheather it has anything to do with whats going on any
suggestions?

Regards,

make sure you allow port 53 for both tcp AND udp.
