RE: Frame Relay or T1 line+VPN.
If I understood you correctly: The way each office connects to the internet should not matter for the VPN. And, the router at each office (the main router, one that sits between the office and internet) should handle VPN. Just make sure each router supports each other for VPN. And, you would only need 1 Exchange server to be on a public IP (only the pop3 and smtp ports open). The non-public exchange servers would communicate with the 'main' exchange server over the VPN. (of course, each router would need a public IP) At the company I work at now, at one point we had VPN going between Frame Relay (main office), DSL (other office) and Cable and DSL residential services. Each VPN location is treated as a different subnet. Once you have VPN working, you can setup your network to use the subnets... Multiple Exchange Sites etc just pretend it's a normal, subnetted network. Exchange does not need to know about the VPN at all. I hope this made sense, and I hope I read your question correctly. Also, there are probably some better ways of doing this, and I'm sure this group will let you and me know about it real quick ;) Andre -Original Message- From: John Shi [mailto:[EMAIL PROTECTED]] Sent: Tuesday, August 14, 2001 2:40 PM To: Exchange Discussions Subject: Frame Relay or T1 line+VPN.

Hi, Andre How about Replication between all the W2K DC on different sites? If you change some configuratin on W2K DC on the central stie, how would this replicate to the remote sites through VPN?

RE: Frame Relay or T1 line+VPN.
John, Replication should work fine... Once the VPN is up and running, you should be able to do whatever you want with win2k, and exchange etc. Getting the VPN setup is mainly just getting TCP/IP to work with all the sites together, in a virtually private way. Once that is working, you should be able to play around with multiple domains and their trusts, and other stuff, because that stuff all uses TCP/IP. You see, Win2k doesn't really need to know there is a VPN at all, it will just use normal TCP/IP operations to communicate across the VPN. To NT, the other VPN site will just be like another subnet. I should note, that theoretically (and maybe someone else can shed some light here) the VPN connection will be slower. Because they are encrypting all the data, so the router/VPN device must encrypt the data(some time wasted there) and once the data is encrypted, it has some overhead. So, you may have to play with replication a little bit, but I think it would work fine. As for your OWA question: That is a good question... Translated= Hmmm, I don't know. I guess at the office, the users could type the internal machine name of the exchange box they want to get to for OWA. But, what if they are at home, ant want to OWA to check their mail? Maybe set up a machine to just serve the OWA, and everyone use the same one? I don't have any real experience with OWA in a multiple Exchange site environment. Anyone else care to shed some light here?

RE: Frame Relay or T1 line+VPN.
I'll take the OWA one. :) The only version info I saw in the email was one reference to one Exchange 2000 server. You'd use a frontend-backend scenario. You'll have to buy Exchange Enterprise for your frontend server. Other than that, you can use Standard version if it suits all your other needs. The frontend server will find the server that contains the users' mailboxes. If you REALLY wanted them to access OWA at their own sites, you'd need to put an OWA server in each place.

RE: Frame Relay or T1 line+VPN.
Then yes, it's a one-to-one relationship. More clients, bigger hardware on the OWA box. You can use SSL. Or if you want to skip the OWA box, just have them VPN in (you ARE implementing the technology, after all) and let them use an IMAP client or Outlook. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Posted At: Tuesday, August 14, 2001 6:28 PM Posted To: MSExchange Mailing List Conversation: Frame Relay or T1 line+VPN.

RE: Frame Relay or T1 line+VPN.
Depends. But yes, in Exchange 2000, technically speaking, you can set up one front-end server and have it handle all of your back-end clients. I don't know whether you have 100 users per server, or 10,000. You really need to go look at the whitepapers at www.microsoft.com/exchange. Nobody here can cover this in the detail it needs. And again, if you're putting the vpn in, OWA is probably unnecessary. Especially 5.x. Sizing on OWA 5.x is done with the simple formula of [number of simultaneous clients] x [resources needed for an Outlook session] = [necessary OWA sizing]. That's oversimplification, and wildly inaccurate, but good enough to give an idea. The users love OWA 2000. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Posted At: Tuesday, August 14, 2001 6:29 PM Posted To: MSExchange Mailing List Conversation: Frame Relay or T1 line+VPN.

Subject: RE: Frame Relay or T1 line+VPN. John, Replication should work fine... Once the VPN is up and running, you should be able to do whatever you want with win2k, and exchange etc. Getting the VPN setup is mainly just getting TCP/IP to work with all the sites together, in a virtually private way. Once that is working, you should be able to play around with multiple domains and their trusts, and other stuff, because that stuff all uses TCP/IP. You see, Win2k doesn't really need to know there is a VPN at all, it will just use normal TCP/IP operations to communicate across the VPN. To NT, the other VPN site will just be like another subnet. I should note, that theoretically (and maybe someone else can shed some light here) the VPN connection will be slower. Because they are encrypting all the data, so the router/VPN device must encrypt the data(some time wasted there) and once the data is encrypted, it has some overhead.

Hi, Tom The central Exchange server has 200 users and all the romote site servers have less than 25 users. How do you think?

But yes, in Exchange 2000, technically speaking, you can set up one front-end server and have it handle all of your back-end clients. I don't know whether you have 100 users per server, or 10,000.

RE: Frame Relay or T1 line+VPN.
I think if I had a T1 or frame relay with a good CIR, and that really sweet VPN arrangement you're deploying, I'd have one Exchange server, one OWA server for road warriors (hey, you already own all those licenses, might as well use ONE of them), and a bunch of sites with Outlook deployed in corporate/workgroup mode & OSTs on less than 25 workstations per site. But that's just what I would do. There's another 3500 folks on this list, most of whom are smarter than I, who may have better/different viewpoints. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Posted At: Tuesday, August 14, 2001 7:32 PM Posted To: MSExchange Mailing List Conversation: Frame Relay or T1 line+VPN.

RE: Frame Relay or T1 line+VPN.
John, If your operating in the UK or Europe, Nextra would he happy to help you develop the VPN solution. The VPN can be like a permanent link, if there are no contention issues. I would suggest the following: Use an ISP that specialises in business usage. Look for the use of MPLS to guarantee your bandwidth. Use the same ISP for all nodes. Use specialist VPN devices (such as Cisco 3000 series VPN concentrators) in each location. Set up LAN to LAN links with DES or 3DES encryption, this will make the VPN look like a regular router link to the clients. (Remote workers can connect to the VPN via VPN client software). This is the way our own network is developing (and we are a business ISP). regards, Richard Dann -Original Message- From: John Shi [mailto:[EMAIL PROTECTED]] Sent: 14 August 2001 22:40 To: Exchange Discussions Subject: Frame Relay or T1 line+VPN. Hi, Everyone The Technology is changing very fast. I was more comfortable with Frame Relay then T1 Internet VPN technology. We have one central site and 4 remotes sites. Originally, I was thinking to keep the frame Relay, but my boss thought the each site has its own T1 line and VPN to our central stie is good as well. The issue is pricing is about the same on T1 to the Internet and frame Relay. On the remote site, we are going to have W2K DC and Exchange 2000 server 10 months from now. The frame Relay contract is going to expire within 9 months. I want to find out if I should re-evaluate the T1 Internet and VPN options or I should keep Frame Relay. How would the W2K DC replication work on the VPN at the different locations? I did not need to think about this when we are in the Frame relay. If I go with VPN through T1 Internet. How would my Exchange server on each site commmunicate with each other throuh VPN? Does anyone see any need that I should keep my Frame Relay based on our situation? If we use Internet VPN on each site, does that mean we need to have public IP address on the exchange server on each site.
