If I have a fibre internet connection with 1 or more static IP addresses and then I’m using drop in mode and failing over to LTE which also has a static IP address, what are the options for remote connectivity if I’m using a BR1 or HD2? Just wondering what most people do.
So for example, if my fibre static IP is 126.96.36.199 and my LTE static IP is 188.8.131.52, if we have remote users or customers that are accessing servers on premise via 184.108.40.206 and that goes down, what do most people do to easily know to connect to 220.127.116.11? We use Route 53 on AWS for our DNS, and I had tested it before creating a DNS entry like remote.company.com, with priority 1 being the 18.104.22.168 and priority 2 being the 22.214.171.124 which did seem to work when I tested it ages ago. Wasn’t sure though if that was because AWS is fast at updating DNS or if that would work for everyone.
I know with the Balance devices you can use them as a DNS server which would be an option but in general we are using more cellular based devices like BR1 or HD2. I’m just wondering the difference between doing what I mentioned above, making 2 DNS records on a current DNS host like Route 53, Cloudflare, etc, vs using a Balance as the DNS server.
Lastly, I know there’s dynamic DNS, but from what I can see it seems to be by WAN, meaning you’d have to set up 2 separate dynamic DNS records, with one for each WAN (like remote1.dynamicdnsprovider.com for WAN1 and remote2.dynamicdnsprover.com for WAN2).
