PIX firewall - block IM and P2P application configuration

Hi all,

Would you advise what is the configuration to block IM(like AOL) and P2P(like BT) application?

Thanks

Re: PIX firewall - block IM and P2P application configuration

Hello Mak,

the first issue you have is to describe the applications. While at first blocking specific TCP/UDP ports seems the best choice, you will learn, that those applications can easily be reconfigured to use different ports.

What you can try is still the access-list approach to block the majority of traffic. You should try to find out which ports these applications are using in your network.

Another option is to use a router with NBAR and "match protocol gnutella" and the like and apply a service-policy to drop this traffic.

Hello,

Can I use inspect http->http-map->port-misuse? If not, then what is the main function of it?

Thanks
