    IPFW Is my IPFW NAT setup ok?

    Hello everyone, over this weekend I spent some time by replacing my PFSense firewall with a FreeBSD IPFW one. Mostly because I wanted the flexibility that comes with FreeBSD and that I can install all kind of third party software on the same machine as it has plenty of available resources...
