You can have multiple external IP on multiple NIC's or assign them all to one NIC. ************************************************************** Tim Comes MCSE, MCP +Internet, A+ Smith Equipment Network Admin. 2601 Lockheed Ave (605)882-8232 Watertown, SD 57201 tim@xxxxxxxxxxxxxxxxxx ************************************************************** -----Original Message----- From: Russ Reed [mailto:russ.reed@xxxxxxxxxxxx] Sent: Thursday, June 20, 2002 11:15 AM To: [ISAserver.org Discussion List] Subject: [isalist] External Interface & Multiple IPs http://www.ISAserver.org If I understand ISA correctly, you can only have 1 external IP address? Assuming this is true, any suggestions on how I should configure my ISA server/network for 2 different IP addresses (with 2 different subnets)? Background: We are a small business with a cable modem as our main internet access (we have 4 public address, only using 1). To provide backup internet access, we are getting wireless internet access (with 1 public IP address). I need to publish servers (the same internal server) on both external IP addresses. Can I do this with ISA?
