Hello, guys how are you doing?


As i mentioned before my internet setting ( WAN) connection type
seems just like this-

Example- # INTERNET SETTING

> Connection type.........PPPOE
> IP Address...............90.138.84.230
( From this the last two HostID is always changing, but ( 90,138, is
constant)
Subnet.......................
255.255.255.255 ( constant)
> G.way......................
64.235.112.254 ( constant)
>PrimaryDNS...............64.234.114.203
( constant)
>secondaryDNS...........192.118.113.102
( constant)

Right now the " www.dynDNS.org" provided me an account for the DDNS.
and i enabled DDNS in the Router. so do you think now i am ready to
install ISA server for both caching and Firewall?

Please Guys i need your help and i am interested to use this
ISA server because i want to secure my network. Please guys i need
your instruction.

Thank you very much
