I am trying to enable Natting on a new Cisco PIX Firewall 515E but I have not managed. I have enabled both interface0 and interface1 but when I connect a cable from my Satellite modem on the ethernet0, there seem not to be any activity. I think I have configured all the IP addresses correctly but I can't manage to connect to the internet. I don't know how to get the PIX to use the gateway and route traffic from my inside net to the internet. I tried to used ASDM but when I loggin it says page can not be found and does not load the application.

Is this normal? Is there something I can do to enable Natting and connect to the net? I have managed to get the DHCP server working but that's as far as I have gone.

interface gb-ethernet0 1000auto

interface gb-ethernet1 1000auto

ip address outside

ip address inside

global (outside) 1

nat (inside) 1 0 0

route outside {Next hop IP address}

access-list 100 permit tcp any any

access-list 100 permit ip any any

access-group 100 in interface outside

If you have 7.X IOS ... than great to easy configure looks like Router.

Enjoy... Have a Best Week End.
