your local ISP provider, you don't get VPS with millions IPv4 addresses, just IPv6.
how it will be working, if you don't get static IPv4? let hear your version of your IT
How to local and remote server dynamic Ip (hostname remote)
Gretap
Write bash script.
Resolve IP from hostname.
Remove and readd tunnel if IP changes.
Setup cron every five minutes.
Gretap working VXLAN working WireGuard awesome.
To GRE tunnel over dynamic IP addresses, you typically have two main options:
WireGuard is an excellent option for setting up tunnels over dynamic IPs. It's simple, efficient, and works well even if the IP addresses change frequently. Here’s why WireGuard is a good fit:
Dynamic IP Handling: WireGuard handles dynamic IP addresses natively. It automatically updates the endpoint IPs when they change, as long as the new IP is reachable.
Security: WireGuard is known for its strong security model.
Performance: It's highly efficient and faster than many traditional VPN solutions.
To set up GRE over WireGuard:
Set Up WireGuard: Configure WireGuard on both ends of the connection, allowing it to handle the dynamic IPs.
Create the GRE Tunnel: Once the WireGuard tunnel is established, you can set up the GRE tunnel inside the WireGuard tunnel. The GRE traffic will be encrypted and secured by WireGuard, and it will maintain the tunnel even if the IP addresses change.
2. Using Dynamic DNS with GRE
If you prefer to use a traditional GRE tunnel without WireGuard, you can use a Dynamic DNS (DDNS) service. Here's how:
Set Up DDNS: Register a dynamic DNS service on both ends. This way, when your IP changes, the DDNS service will update the hostname to point to the new IP.
Configure GRE Tunnel: Set up the GRE tunnel using the DDNS hostnames instead of static IP addresses. The tunnel will automatically adjust to IP changes by resolving the DDNS hostnames to the current IPs.
Summary
WireGuard: Ideal for handling dynamic IPs seamlessly with enhanced security.
GRE with DDNS: A more traditional approach that works if you prefer to keep using GRE without the additional security of WireGuard.
If you're already using WireGuard or are open to it, that would likely be the most straightforward and robust solution for your needs.
