I would like to provide some redundancy. I have 2 DSL lines which each have several IP's from my ISP.
I have a server running on an internal network (e.g. 192.168.1.254/24).
I have 2 ISP connections, we can call them connection 1 (e.g. 184.108.40.206/24) and connection 2 (e.g. 220.127.116.11/24)
I would like requests to a website (e.g. www.mywebsite.com) to be forwarded to both 18.104.22.168 and 22.214.171.124. My edge routers would then forward the request to the server (e.g. 192.168.1.254/24)
It is particularly important to me that if either connection dies (as the router overheats! or the ISP fails!) then the remaining connection should be used to carry all the requests.
