Ip conflict problem

[Wicked2000]

Hi.

I am going to use Wingate on my server to test how it performs on my network, The biggest problem that I have is Ip conflict and I wonder if Wingate has any tool or something that could help solve this problem.

My network is bulid like that.
I have a router that connects to the internet and the router gives internet access to the server and that server has 2 network card. The router has DHCP enabled and it give IP address to the server. The second network card has 2 IP address. one is 192.168.0.100 and the other is 10.0.0.100. With Dhcp software that gives DHCP address only to 1 IP address. The other IP is for computers that I don't want to block their speed and don't want other people to enter those computer.
Everything is working excellent except for one thing.

The problem is that the second network card on the Server is connected to an Wireless AP that gives to a lot of people internet access. And while people are getting IP address from the dhcp and surf without any problem. Sometimes I'm getting an IP conflict that stops the network card and all the people that suft wireless don't have internet access.
Of course the DHCP is not set to not give IP address of the server.

Is there something that Wingate can help me with that? Some feature or something that it has. Because I am going to Install a proxy soon. And I find you on google and download the trial and test it and it works great but I didn't find anything that could help me against this problem.

And the second question is: if I can configure Wingate to be a transparent proxy?

Thanks

Hi

WinGate will work as a transparent proxy. This is on the sessions tab of the proxy server - connection intercepts. You can specify the ports you wish to intercept per proxy.

As for the network IP conflict, normally when such a conflict is reported, it reports the ethernet address (xx-xx-xx-xx-xx-xx) of the conflicting network adapter.

Have you managed to track down where this conflicting adapter is installed?

Thanks for you answer.

I don't see the MAC address of the card that cause the IP Conflict. How can I see it?


It's going to be a problem to know who did it. Because the internet is shared and it's connected to a wireless AP that connects a lot of people outside my office.

I thought about this option to block that IP Conflict. To install a firewall or use Wingate's firewall. And set a rule that the computer will block the IP that I set to my network card.
That way it will not talk to an IP the same as the server.
Good way?

If the ip conflict is happening on a windows machine, you can look in the eventviewer and see the mac address.

You can always set up your dhcp service to not assign the ip address that is causing the conflict.

Of course I set the DHCP to not give the IP address of the server. That would be stupid.

What do you think about the Firewall the has a rule to block any communication from any outside computer that has the server's IP.

To do that, just add the ip to the blackhole list in extended networking.

It's that easy?! :)
