We are in the process of setting up a bastion host. One of the things we'd like to do is to filter packets not only at the ip layer, but by what program is listening on a particular port. Is this a possibility? A quick 5 minute Google didn't provide me with anything noticeable, but that my just be my noobness in the *BSD world. So play nice! ;-) Thanks for any suggestions! Kevin
