in our organization we have one win 2k server and 30 workstations. we use internal IP and we are conected to the net useing DSL and a a modem that acts as NAT. recently I insatalled exchange 2000 and we opened the e-mail ports on the modem to my server so we can send and recive from the interent. now i was wondering if i need to install ISA server on my server for security reasons or i'm fine since my server is behind the modem's NAT. I'm asking this b/c i've heard of many problems that ISA canhave on a PDC.
please let me know of your experienced with ISA 2k

thank you

the best solution is if you only opened the ports required for mail then you should be fine using the nat technology. I would not suggest installing isa on a pdc. The fact that you are behind the nat is pretty good. the Best solution is of course atrue firewall in between the router and the mail server. This a know is not an option but is the best solution. You may even thing of using a different box for isa and put it in front of the exchange server! to install it on the pdc/exchage is not avery good idea!
hope this answer your question!
