Can someone offer guidance on HOW a DSL router should be configured to allow proper "PASS THROUGH" to my ISA server, which will sit right behind it in the enterprise. Do I want the router to be configured to do "router duties", or do I want for it to be configured to be "transparent" and then let ISA do the work? And confirm, NAT should be turned OFF on the router, correct?? Glen Howard II, MCP Systems Administrator ghoward@xxxxxxxx Barnes & Noble.com "If it ain't broke, BREAK IT..
