Hi guys,

OK I have the exhcnage server, the SQL servers, and the VPN Server all behind the firewall, and they are all in one location. I can check my email from anywhere with no problems, but when I start a VPN Session to the VPN Server (Windows 2000) for whatever reason I cannot check my email. when I go to our website and click on logon to email, it takes sometime and then times out to (The page cannot be displayed). as soon as I disconnect the VPN everything works just normal.

can someone help out please?

thanks in adavanced

Go to the properties page of the VPN conection
Networking Tab
Properties of TCP-IP
Advanced
Uncheck 'use default gateway on remote network'

That should fix your web browsing problem and maby even your email..

You are connection to the Exchange Server by its internal (LAN) address through the VPN aren't you?

Cheers

that's no it.

I am connecting to the exchange over OWA, and it uses the pub address. I also have to use the gateway on remote computer network to be able to access some resource over there.

Sorry zaneyfunster, and thanks for trying

If you are using the gateway on the remote network over a vpn, this means that any web pages you view are accessed over the vpn and via the internet connection at the other end.

The result of this is really slow internet access, lots of time outs and all sorts of routing problems like you are having.

If you REALLY need to use the remote gateway, then you will need to access OWA via it's internal address, OR fix up the DNS on your server to route requests from the internal network to the public address so that it will resolve to the internal address of your exchange (OWA) server, or it will not work.

The only reason I can think of for Needing to use the gateway on the remote network to access resources is if you have a further VPN from the remote server to these resources elsewhere. Is this the case?

Otherwise, if you use your local gateway, then all Public requests will go out through your own internet connection (Browsing the web, accessing OWA), and all internal IP requests will go through the VPN.

If there is a problem accessing a resource, then perhaps you are running more than one internal ip address range. To remedie this, create a lmhosts file.


If I am a long way off, please provide me with more information as to what the remote configuration is..

Cheers

zaneyfunster,

Thank you so much for taking trying to help me out.

Ok I have the exchange server, and all of other server in a network that has IP Address i this range: 192.168.50.X, and when I connect with the VPN of course I get an IP Address i this range.
I am really not trying to fix this problem for my self, but for the President of the company who likes to always stay connect with the VPN while browsing the web and accessing his email over OWA.

The server that runs the VPN has two interfaces, one with IP Address of 192.168.50.16, and the other interface has IP Address of 10.0.0.16. The 10.0.0.16 IP Address is not being used in the network any more, so do you think that has anything to do with the problem.

Thanks man

What is the resource you need to connect to via the remote gateway?
