Please help... what is a good way to establish a static IP for my homelab if the ISP doesn't provide it? (alien.top)

I have several machines that need direct in/out traffic through router port forwarding.
I have things setup already right now, using my domain name , pointing at my current static IP issued by the ISP.

But I will be transferring to another ISP and they don't offer static IPs. What's worst is the IPs issued are not only dynamic, but also private (so dynamic dns solution can't help)

So I need a way to maintain my exact setup (and port forwards) on the new ISP and I'm willing to pay for VPN like service if I have to. But I heard routing traffic through VPNs will slow down traffic which is my concern. I'm assuming VPN traffic is slow because of it having to hop around lots of proxy servers? If there was a VPN that just gives you static IP w/o proxy hopping, that would be best. I don't need the privacy, i just need the static IP and speed.

Looking forward to some helpful suggestions.

Tailscale and a cheap VPS running the exit node tends to be a common route.

Lets you expose services out without opening anything localy and gets you full control out from the VPS without ISP meddeling.

There are other alternatives but tailscale has the best free tier with upto 100 devices, exit node+router, solid access control and mfa.

hmmm i see.. i've head bout tailscale.. but how's the speed? will all traffic from home have to go thru the VPS (slowing down connection, and consuming costly VPS bandwidth)?

You can get a a VPS with unlimited bandwidth, I use IONOS at work, it’s a 500mb connection on their end (1gig at work) we have multiple people streaming video/downloading files without issue.

wow, ok, tnx for the leads.

[–] cruzaderNO@alien.top 1 points 11 months ago

Tailscale negotiates a direct VPN to the VPS and all traffic going through the VPN goes through the VPS.
As for bandwidth its not really that expensive unless you need like 30-50tb per month type numbers.

If its specific machines you can install tailscale on those also and they make a direct connection.

I got on my phone,laptop,tablet etc so wherever i am it will use tailscale as middleman to find open ports and establish a vpn to home network.

Instead of the "cheap VPS" part, you might find you can use one of the free instances you can get in Oracle Cloud's free offering.

...and WireGuard it together. I also did this before I got static IPs...

Well, I used it as a VPN to go home, but the principle is the same.
