who can tell me alias command's function

topology like this:

inside lan ------pix---- outside internet

lan ip : 192.168.1.0

lan server ip : 192.168.1.100

outside ip : 60.60.60.60

outside server ip : 60.60.60.100

somebody tell me the alias can achieve functions like below:

rewrite the DNS packet's address with inside address

when my inside host 192.168.1.2 want to access the inside server's web pages.

the inside host enter "http://www.alias.com" into the IE address bar.

and he will get the DNS answer of 60.60.60.100,that address is the inside server's nat outside address in fact.

if we don't use alias command,we will not get 60.60.60.100's web pages.

using alias,the 60.60.60.100 will be rewrite to 192.168.1.100.

my question is , if alias can only change the DNS's reply?

if alias can help us,when we type url "60.60.60.100" directly from our IE address bar ?

Alias would help you here if your server was on a dmz. But since the server is also on the inside alias will not help you. I assume this is pix version 6? Version 7 would allow you to hairpin on the inside interface and use destination nat. Something like this...

static (inside,inside) 60.60.60.100 192.168.1.100 netmask 255.255.255.255
