Help Network configuration with ASA 5505

Help Network configuration with ASA 5505 was created by buLLs
Hi
. I hope my english will be enough good to explain my problem :roll: and also my network skillz...i am very noob..but everyone has to start from somewhere 
This is my actual network configuration.
internet -- pc
My ISP gave me this configuration:
IP : 89.201.240.176
Netmask : 255.255.255.0
default gateway : 89.201.240.1
DNS : 212.23.32.70
DNS2 : 212.23.33.70
following this rule i the ip of my computer is 89.201.240.176, default gateway 89.201.240.1, dns 89.201.240.1 and i can acces the web.
I just got an ASA 5505, i tryed to configure it but i'm stucked =X i can't acces the web.
The steps i followed are:
1) I disabled the DHCP on the inside vlan and set the ip to 192.168.0.250
2) I disapbled the DHCP on the outside vlan and set the ip 89.201.240.176
3) I set the default gatway of the firewall with the command :
route outside 0.0.0.0 0.0.0.0 89.201.240.1 1
4) After spamming thousend thread & guides around the web i also checked the "dns rewrite" option for the nat rule.
At this point my config is:
ASA Version 8.0(3)

Now the inside vlan is working and i can ping the firewall, i tryed ping the ip of google and it works, but i can't acces the web typing the URL on the web browser.
What do i have to do, what am i missing ? :oops:

What interface is your computer connected to on the ASA and what are the network settings you put on the computer?
