ok here you go


conf t
int eth0
ip nat outside
int fa0/0
ip nat inside
access-list 1 permit 192.168.0.0 0.0.0.255
ip nat inside source list 1 interface eth0 overload
ip dhcp excluded-address 192.168.0.1
ip dhcp pool DHCP_POOL
network 192.168.0.0 255.255.255.0
default-router 192.168.0.1
dns-server X.X.X.X Y.Y.Y.Y
hostname BLAH

end


try that if it works make sure you do a copy run start.
be sure to change the x.x.x.x and y.y.y.y so valid dns servers for your isp.

You are missing the nat acl and applying nat to PAT (overload). Also, all interfaces should be auto duplex, not hard-coded. Speed and duplex auto.

thank's burtsbees
but the duplex not work auto
and the internet it still not receive in host

originally you had your gateway set to 192.168.0.1.. now your interface is .2..

and you are giving them the .1 as dns servers.. you need to assign your public dns servers from your isp.

im sure you ip connectivity is probably fine right now but your dns resolution isnt and thats why you cant browse.
