I would like to use the firewall the same way ms proxy 2.0 is used. Basically, do I have to open port 25 on Linux and have it rout that traffic to exchange?... thanks, Fred Valdez GSRINC Network Administrator List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm
