How to configure/route two DSL connections?
Posted on 2007-03-27
I am suffering from a slow Internet connection. It is being brought on by a new Internet training program that our company is using that is delivered as streaming video. I have investigated different alternatives. Before I start spending money I want some external input on what I’m thinking. As well, I am open to other thoughts for possible solutions. Last, if the path I’m headed down is a good one, I need to know the specifics of what settings need to be set/changed on which devices to accomplish the intended goal.
Please realize I am a business owner and handle 99% of my network work. However, I have no formal training. As long as the jargon doesn’t get to complex I can accomplish just about anything with the excellent assistance I receive on this forum.
I have a small network spread across two stores. At store one I have the following equipment: a server running SBS 2003 and Exchange, an Altigen VoIP server, 4 workstations running XP Pro, and my Internet connection with a Watchguard firewall and my Internet connection. It is a 10.0.0.0 255.0.0.0 subnet.
At store two I have the following equipment: a server running: Server 2003, 7 workstations, 6 VoIP phones. It is a 192.168.10.0 255.255.255.0 subnet.
The two offices are connected via a dedicated PTP T-1 with Adtran (3200 & 3205) routers at both ends.
The current Internet connection is AT&T (formerly SBC). It is 1.5 Mbps down and 384 kbps up. When I spoke with AT&T they told me that due to the distance from the CO, I have the fastest that is available.
At store two, I can get 6.0 Mbps down and 768 kbps up from AT&T. However, the current (slower) connection has a TRUE fixed IP and never goes down. It is grandfathered in regarding the fixed IP, as long as I keep it. You can no longer get a true fixed IP address from AT&T. They charge you for a fixed IP then give you a “sticky IP” that connects with PPPoE. I have that service at my house so that I can use the branch office VPN feature on my Watchguard firewalls to connect to the network. On that connection, the “Sticky IP” unsticks at least twice a day. It is very frustrating.
I tried contacting Covad because they have real fixed IP addresses. However, store two is only 1000’ from a remote terminal and Covad can’t access that remote terminal. Therefore, they show the location being 11,000 feet from the CO and can’t offer anything faster than my current connection at store one.
My proposed plan is to add the 6.0 Mbps connection at store two with a dynamic IP (to save costs). Then, I want to accomplish my branch office VPN and Exchange server connections across the slower connection with the true fixed IP. I want all of the browsing to be accomplished via the faster connection at store 2.
I am having a little difficulty figuring out if this is possible. And, if it is, how do I point the appropriate equipment in the correct direction to use the desired connections.
All input is greatly appreciated.
