Pix firewall and access to internet problem

Unanswered Question
Jan 6th, 2008

Hi expert,

I got one Pix Firewall before connection to internet. I have problem with the internet connection to certain website, or I can surf but in very slow response time. But, if I bypass the pix firewall, I able to access any website with great response time. Wonder whats the problem with the Pix firewall. Here I attached the config for reference. Your brilliant ideas highly appreciated. Thank you.

I have this problem too.

Try this first :

fixup protocol dns maximum-length 1024

See if that makes any difference .

In case it does not set up captures and see where ther time delay is happening.

My internet connection design is like below:

LAN --- Switch --- Pix Firewall --ADSL router --internet
