I want to block my outbound traffic with my Cisco PIX 501

[Flixxie]

I have a Cisco PIX for experimental use.
My problem is that all outbound traffic is allow?
Is there someone that can help me to block my outbound traffic.
Here is a example of my cisco script.

By default, traffic is allowed from high security interfaces to lower security interfaces without an access list. In your case, all traffic is allowed from "inside" to "outside".

To stop traffic from the inside to outside, you just need an ACL like you already have on the outside interface. For example, if you want to stop HTTP and HTTPS traffic, you could use:

access-list 102 deny tcp any any eq www
access-list 102 deny tcp any any eq 443
access-list 102 permit ip any any

access-group 102 in interface inside

The "permit ip any any" command at the end allows all other traffic out. If you omit that, then no traffic will be allowed to pass. If you really want to block everything, then use:

access-list 102 deny ip any any
