I have a problem with my small business. Here is a quick background. I have a small business with three locations that uses an application which REQUIRES high availability to a server that is located at one of the locations. The data must be secured by a VPN. I am currently using 3.0/768 DSL at each location with static ip addresses. I have reliability issues with the DSL at all three locations but the problem is sparatic and Verizon has gone as far as sending techs out to all three locations to check the lines. All lines appear to actually be great when their techs are there. The consensus is that the sporadic outages are due to wan traffic and the fact that DSL has the lowest priority. Their suggestion is to go with T-1 which is far too costly for my small business and other lower cost lines are not available at my store locations. Cable is an option but my personal experience is sporadic outages for up to two hours at a time with my cable/data provider (which I use personally). My idea is to purchase a router with 2 wan ports for each location. I would use one port for DSL and one for cable. $65 and $80 for DSL and Cable modem is a much more financially acceptable alternative to the $550 T-1 suggested Plus it would provide real redundancy. Here is the routing problem. The application can only point to one ip address for the server. Here is my question: If I create a VPN between one location and the location with the server and either the DSL or Cable goes down, will the RV042/082/016 properly send the request for that 1 ip over the other that is up. Additionally, If both cable and DSL are up will I have any problems with the request sent or received twice leading to data corruption? In other words will they load balance the VPN (If one tunnel goes down will it try the other tunnel with the same request)? I would also appreciate any help with this or any other suggested solutions you may have. You should know, I've tried the Co-location thing and customer service never seems to respond fast enough and I still had outages because my store locations connections are the weak point. Thanks in advance for any help!!!! If this seems confusing or doesn't make sense, feel free to ask questions.
