IIS query!!!

[Harry]

Hi!
I did post this in server.general - but to reach to larger audiance Iam
reposting it again . Assistance required.....

I have a computer running IIS with a public IP(x.x.x.x), now I want the
port 80 of the public IP(x.x.x.x) to be used by another program.
Is there any way I can make both the programs up and running accepting
requests on port 80 of x.x.x.x?
If not... can I assign another public IP (y.y.y.y) to IIS and let it
accept incoming requests on port 80 of y.y.y.y?
As of now I have only one NIC.
Thank you in advance
Regards


You can assign multiple IPs to your NIC. Go to Network Connections,
right-click your NIC, select Properties. In the items list select
Internet Protocol (TCP/IP), click Properties, I assume "Use the
following IP address:" is selected. Click "Advanced" - here you can add
multiple IP addresses

Hi!
Many thanks for the reply. The other application Iam using is Ultravnc, and
I want it to listen on port 80.
Well, I've added another WAN IP(x.x.x.x) to the NIC as you told me and made
IIS v5 to use that IP and listen on port 80.
I configured an WAN IP (y.y.y.y) as "Use the following IP address" and the
ULtra VNC will listen on this as this is the configured IP.

But, at any given time only 1of them is working( either VNC or IIS).

Any ideas???

Thanks
Harry

Correct. You can assign multiple IPs to your NIC. You can use netstat command to check the port status. This link may help,

Thank you for the reply.
I have assigned multiple IP's to the NIC a) 202.x.x.172; b) 202.x.x.173.

I have assigned IP 'a' to IIS and made it listen on port 80 of that IP.
In the network connection - " use the following IP address" I gave the IP 'b'
I have also specified both the IP's in the "advanced - IP address" of the network connections.

With the above settings - I understand that IIS should listen on port 80 of IP 'a'
and the ultraVNC should listen to port 80 if IP 'b' - Right ?

But thru "netstat -ano" I see "proto - TCP", "Local address - 0.0.0.0:80" with the program ID for IIS - when IIS is started first.
But when I try to open UltraVNC it gives error. Thsi is obvious because IIS is already using port 80
The vice-versa happens if I start IIS while UltraVNC is listening on port 80.

Looks like both the programs are using port 80 of a single IP.

Iam able to get the reply of Ping for both the IP's.
I dont know if Iam missing something. Any idea what Iam doing wrong?
