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 =P

This is my actual network configuration.

internet -- pc

My ISP gave me this configuration:
IP :
Netmask :
default gateway :
DNS2 :

following this rule i the ip of my computer is, default gateway, dns 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
2) I disapbled the DHCP on the outside vlan and set the ip
3) I set the default gatway of the firewall with the command :
route outside 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)
hostname ciscoasa

interface Vlan1

: end

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?
