Hiya folks. I’ve been using this for years and really love it- thinking about starting a second server for a personal project, but the second machine would not have a static IP available like I have at the office.
What is the most popular method for routing traffic to your servers when a static IP isn’t available?
Cloudflare works great and I haven’t had any issues in a couple of years. I use pfSense to update the IP but there are other methods that you can find.
I use dynamic DNS (DDNS). A small service runs on a server and periodically updates DDNS with your IP address, e.g. yourname.freeddns.org. You then set-up DNS to refer to this CNAME, e.g. CNAME simplehelp.yourdomain.com maps to yourname.freeddns.org
The downside is that this isn’t instant (DNS updates aren’t instant) so there can be periods when simplehelp.yourdomain.com still refers to the old IP address. Setting low TTL the CNAME will help.
So not routing as such. I assume CloudFlare acts as a proxy?
Cheers fellas, looks like another thing to learn on my calendar. 
Also, some routers have DDNS clients baked into them. Mikrotik does for sure.
Simple Help doesn’t like to be proxied as far as I can tell but Cloudflare updates fairly quick…I think because it has never been an issue. TTL is set on auto and they say that is 5m.
