windows server.. switch ip without deleting aliased IPS?
 

Hey guys, i have a windows box with lots of IPS.. My tech is stumped and so is another programmer im using.


Is there a way to switch IPS in the windows box WHILE keeping the aliased IP..

Basically i have a tool that will switch the main IP(outgoing) of the box, but whenever it does that, windows also deletes the alised IP(Ip im connect to using rdc,etc), so i end up getting kicked offline...

Is there a way to switch the main IP of a windows box without losing connection to the current IP you are on..

I hope this makes sense

I used to have 13 windows boxes on win 2003 servers, but its been at least 2 years since I have messed with win servers. There is a way to do it, but I can't even begin to remember how I did it lol. I ran gaming servers so I did a lot with Ip assignments.

yea i know theres a way to do it.. come on think hard.. this has me stumped for days and ive been paying guys who cant figure it out yet.. im losing $$ :(

We used a tool similar to this http://firedaemon.com/ which allowed ip assignment on startup. Forget the name of the tool, not sure that firedaemon would have any use to your particular situation though. GrumpyAdmin on gfy is pretty good with server stuff, not sure if he is a win expert though.

i need a tool to automatically switch external ip

Why not just remote to a different ip that is bound to the box?

The best solution here is to have whichever software you are using specifically bind the new IP for its outbound connections, rather than juggling the interface IPs directly.

Kind of what I was roundaboutley saying hehe. :winkwink:

can a software bind an IP even though windows isnt..

I BELIEVE you have to have all the ips assigned to the box setup as available, then you can bind per application. Its really been so long I just won't be a lot of help anymore hehe.

I am curious too, is it possible to run some kind of internal proxy idea where you could run the server on its main ip address and have software like IE able to access the internet on different ip's that are assigned to that server? and would it be possible to run multiple instances of IE at the same time all on different ips?

Yes. :2 cents:

this should be pretty simple with multiple nics

can you point me to any resources to figure this out?

I've got a windows dedicated that I haven't really used as much as I should be......

:thumbsup:thumbsup

how so?..........

Can't remember, but yes it is doable.

Here is a tutorial describing how to do it ->

Install a extra NIC (network card) and make that card nr2 in the accessorder. The IP you assign to that card will be your management IP from now and should preff remain the same.

Then you can change the IP's without dropping your connection.

The reason it drops the other IP's is properly because you change to a different subnet. It cant keep IP's on the same nic that is on a different subnet (well, it can, but it need a workaround)

Yes. Install MS ISA server and create different groups, each with its own outgoing IP through the virtual NIC's you created bebore. Then launch IE with specific proxy settings for each instance of IEexplorer.exe

Make sure the guy that sets this up in ISA knows what he is doing, or you end up with a server that dont know where to route what, and what NIC that to answer what service

thanks for the answer, it looks like it is a little more involved than I was hoping, I have windows2003 running already on the server and it is hosting a busy website, so I can't really shut things down and redo the server.... I was hoping there was an easier way to assign an ip to an application within what is already running

You dont have to reboot the box after installing the ISA server software, and it dont conflict with the running services or webserver, as long as the tech knows what he is doing and set up the rules in the right order.

If he dont = you are fucked :)

time to get a better admin? why not ask your host?

or switch to linux, where such things are much easier?

I'm not sure that makes its easier to do. I think the reason some see its as "easier" with linux/unix, is the amount of skilled tech available for that platform.

There are numbers of ways to do what was requested here. Both using ISA server, quality of service or Group policies. But I would never recommend someone to implement that on a "live" server, unless they had tried it before and knew the official Microsoft Best Procedure flow
