We currently have a fairly simple set up, we have ONE public Web Server IP. Our In/Out path is ISP line to our Cisco ASA/Firewall to our Host Server. We use Static IPs from the ISP. Our objective is to achieve highly reliable access to our Web server.
We are looking at solution such as DNSMadeEasy + DNS Failover.
Would the following plan work?
1) We'll acquire a new ISP #2 service as backup for our ISP #1 service.
2) We'll acquire a new Switch. On site our location we'll plug the two lines from ISP #1 and ISP #2 into the new Switch.
3) Run a single line from this new switch into our existing CISCO ASA router, and add configuration rules to Cisco for the new source IP addresses to mirror the rules already there for NAT, port forwarding, etc.
Any recommendations would be appreciated!
