I'm not sure if it's even possible to have two zones on the interface. -- ----------------------------------------------- - Nick Bright - - Vice President of Technology - - Valnet -=- We Connect You -=- - - Tel 888-332-1616 x 315 / Fax 620-331-0789 - - Web http://www.valnet.net/ - ----------------------------------------------- - Are your files safe? - - Valnet Vault - Secure Cloud Backup - - More information & 30 day free trial at - - http://www.valnet.net/services/valnet-vault - ----------------------------------------------- This email message and any attachments are intended solely for the use of the addressees hereof.
