Redundant inbound and outbound internet connections via Cisco hardware
Hi Experts,
I'm currently in the works of deploying a redundant / load balancing internet setup of my new company.
Basically:
ISP A = Main incoming Connection: for Citrix and Exchange email, i.e. RPC-HTTPS connections
ISP B = Backup Line or used primarily for outgoing connections.
I'm aware the the ASA Firewalls provide an effective solution for seamless outbound connections between 2 seperate ISP connections, but not inbound. I know i could just reconfig public DNS entries, but i'm looking for an automated solution. Preferrably Cisco based.
Please advise.

I see, so just map 2 public ips to the same DNS record and point to the same internal ip address, correct?
But how does that work when those DNS records are pulled for service?
is it random between the identical DNS records or what order?

And I ask in terms of just regular DNS records, not MX

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
The same theory can be applied to other incoming connections (two DNS entries per service).
