Hello, I have a Cisco 776M ISDN router with only allows PORT ADDRESS TRANSLATION. The router is also a four port hub. I'm only using one of those at this time. The router also takes care of the dial up to my isp so all I really have to do is connect to one of the ports. Should I run an uplink cable into a switch that contains a cable going into my ISA server and another cable connecting my DNS server? If so, what is the best way to publish the DNS server so that ISA will point to internal sites? My ISA machine has two nic's one external and the other internal. Thanks, Joseph
