Firewalls That Work With NetShow
Firewalls are administered by corporations to prevent unauthorized access to corporate networks. Most firewalls are based on packet filtering. Packet filtering takes place when the computer examines the source and destination IP addresses of a packet and forwards only those packets for which access has been granted. Additional information on firewalls is also available in ASF form and in Q & A form.

NetShow content streaming from Microsoft NetShow will stream through a number of firewalls, and we are working with many additional vendors for support in their products. This page on
