[njtektip]

HI, JUST WONDERING IF ANYONE CAN TELL ME IDF THIS CONFIGURATION I HAVE ON MY CISCO 1760 ROUTER IS THE BEST AND SAFEST WAY TO SET IT UP. I HAVE 1 WIC 10ETH WITH AN EXTERNAL IP CONNECTED TO MY ISP BACKBONE TO INTERNET. I HAVE THEN SETUP MY HOSTS WITH PRIVATE IP ADDRESS'ie 192.168.16.x - THRU A SWITCH TO THE BUILT IN INTERNAL 10/100ETH PORT ON MY ROUTER. I HAVE THEN SETUP THE EXTERNAL INTERFACE TO NAT MY OTHER IP ADDRESS' TO THE INTERNAL HOSTS, ALLOWING ONLY CERATAIN PROTOCOLS THRU RESPECTIVELY.ie. SMTP FOR MY MAIL SERVER, HTTP FOR MY WEB SERVER. WILL THIS CONFIGURATION SHOW MY EXTERNAL IP'S AND MOST IMPORTNATLY - WILL MY HOSTS BE SAFE BEHINF THIS CONFIGURATION ? ANY HELP GREATLY APPRECIATED !
