I am not much experienced with routers.
I have 2 DSL connection from 2 different ISP's. Both Static live IP range. One is 168.x.x.x/28 and another is 194.x.x.x. /28. My MX record for Mail is on 168.x.x.x I want the second ISP also to come into the same Router and serve the users. If one ISP goes down, I require the othe ISP to still provide me with Internet services and Mail services. Which Router is best sutiable in this scenario? I was reading the docs and found Cisco 1811 Integrated Services Router may server the purpose. Am I correct? If not, what are the suggestion.
