I am building a Packet Filter firewall and I am looking for what client TCP/UDP sockets I should let back through into 
our network. We have no inbound access to services on our network.

I assume the range would be 1024-5000 is OK but there are some holes like 5nnnn for Openview and 7000 is font 
serving. Maybe a list of all service sockets would be the best way to do this ?
