Hello networking community! I need a setup where I can forward my server from my private network to another network which has a public ip to forward the server itself to the internet. When a client connects to the server, traffic should get forwarded to my private network somehow. I know that’s possible, but don’t know how I can achive that.

Came back after a year, got some knowledge. I achieved this setup using WireGuard (+ PersistentKeepAlive) and custom iptables rules on an old laptop with barebones arch install. By masquerading, we loose the source ip when forwarding, and to preserve it we need a L2 tunnel (L2GRE).

    So, I can receive incoming traffic using IPv6 despite I don’t even have a public ip? (nv my ISP doesn’t support IPv6)

      If you have IPv6 connection and the address starts with “2”, then your public address is the IPv6 address.

        Nope it just doesn’t support it. I tinkered a bit in router config enabling IPv4/IPv6. But didn’t get IPv6 address from ISP. Still using ADSL2+
