2 servers, 1 private network and one modem. forwarding options
im not sure if i should be using a hardware or a software solution for this but i'm hoping you folks could shed a bit of light on my situation...
im looking at hosting a web & sql server on "www1" and mail & ldap on "mail1"
now i will be using 2 public ip addresses for these 2 machines but will also have a 3rd address to use for my private network.
is there a software package that will let me forward specific packets or ports to specific servers on seperate ip addresses?
do i NEED the seperate addresses or can i send http requests to www1 (or www2 if www1 in down? ) and mail requests to mail 1 (or mail2 if mail 1 is down?) using port or packet forwarding?
if i use a port/packet forwarding solution, am i able to run a private network behind these machines using private class addresses?
im sorry if i sound a bit newbie-ish but i'm still rather new when it comes to linux.
