Hi, Since I have replaced our old firewall with a PIX 515, people complains that they can not see some sites, it says Done with a blank screen. for some sites if you refresh you can see the page and for some others refresh wont help. Does anyone know how to fix this?
Thansk in advance-Rob

You -might- be hitting MTU problems. Are you permitting inward and outward icmp unreachable ?
No, also MTU settings:
mtu outside 1500 mtu inside 1500 mtu DMZ 1500
the line is Fibre. Any other idea? Rob
Not so much the MTU of your PIX interfaces, but rather MTUs 'upstream'. You probably need to allow incoming 'icmp unreachables' on your outside interface.
