I have a networked environment. with exchange 2k3 installed on windows 2k3 server. i created a domain in that networked environment but its not a registered one to the internet. that is it is a local domain. i have a broadband (ISP) which is aol. i created an outlook internally for the users . How can i recieve or send message through this to the internet like yahoo? I also want to establish vpn but was difficult. do i need a phone line to operate vpn? or only broadband? should the line that comes in to the environment go through the computer or ? please i need help. Also, the ISP ip that comes in is 192 168 0 ..... this is also the one i used but occassionally encounter some problems but the question isĀ  can i use my own dhcp and give like a private network? different from the one sent in by the isp's dhcp? after have done this , how to i link to the internet?

Software/Hardware used:
microsoft 2k3 server,xp, windows 7

Thanks. We'll let you know when a new response is added.

First goto justhosts.com (or any other webhosting company) and register a domain name. Then you can now have two scenarios a) Your exchange server receives mail from internet directly, or b) it pulls mail from your Hosted email accounts using POP3.
The second scenario will be easier for you. Just create email accounts on the Hosted accounts and then configure your exchange to pull mails ( if you have an SBS server the POP3 retrievla software should be included, but if not, you can buy any http://www.msexchange.org/software/POP3-Downloaders/name/.
Then you need to speak with your ISP, it seems you are given a Private IP address which cannot receive or send traffic directly to the internet. They can either give you a smtp relay on their network or perhaps ask you to upgrade and get a Static IP address. The second option will be a bit more costly, but you’ll be able to access your Exchange server from the internet and also configure your VPN.

Server 2003 supports VPN, you can configure it from the RRAS. Detailed information on how to do this is available on the internet: http://support.microsoft.com/kb/323441.

Happy deployment…………………….!

I think the IP you are looking at comes from an internal router, not your ISP. Run IPconfig/all from a command line and you will see what your isp dns servers IP addresses are. That is the same range they send to your modem. What is connected to your modem? If you have a router like linksys then that is why your IP is 192.168… Yes you must register a domain name to send and receive email from your exchange server. You will also need to <a href=”http://www.computerperformance.co.uk/exchange2003/exchange2003_MX_records.htm”>create mx records in your dns</a>.

    You need a public domain with MX records. You have already invested the money in your mail server. A public domain is the smallest cost of all.

    The VPN portion of your question, you would need a device that can handle VPN connections. Many home routers now are able to do VPN connections, if not you would have to setup a linux computer to be able to take vpn connections or get a device that can. Another issue I THINK you might have, is that you probably have a dynamic public IP address. This would make things difficult for you, so if you can get a static public IP.

    HI, You got some answers about public domain and VPN - now some about public/private IPs. You shouldn't have same IP ranges on the outer and inner network interfaces - it's not impossible, but it is bad thing and sure can cause a lot of problems. So, if your ISP sets your WAN (outer) IP to, say, 192.168.0.1/(32/31/.../24, whatever), you set your LAN (inner) IP to, say 192.168.100.1/24 and set your DHCP server - or your LAN static IPs accordingly. If your outer IP is from the private range (10.0.x.x, 192.168.x.x, etc), and your ISP is taking care of NAT and DNS, you can use external mails (yahoo, gmail, etc.), and as well any external services with clients on your local LAN. However, if you want some services residing on your LAN to be accessible from the internet (VPN including), you'll need an IP from the real range, preferably static with a domain name attached and appropriate DNS (as already said by ITAddict). Domain and DNS are not obligatory - but if your real IP is not static, better use some Dynamic DNS service. BR, Petko
