Cisco PIX 515E Natting

philipmusyoki · ‎07-20-2007

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.

Try adding this.

nat (inside) 1

global (outside) 1 interface

route outside 0.0.0.0 0.0.0.0

global (outside) 1 204.69.198.254

nat (inside) 1 0.0.0.0 0.0.0.0 0 0

route outside 0.0.0.0 0.0.0.0 {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.
