Hey there, I'm trying to get Nextcloud running on my Raspberry Pi 4 with two 1TB external HDDs in RAID1 for backup. I want to access my files from university, on the move, and at home via LAN and Wi-Fi. I can set up Nextcloud locally and reach my devices like desktop, notebook, and smartphone over the network. The tricky part is networking: my ISP is Unitymedia (now owned by Vodafone), which recently switched to a new modem-router mix. I'm stuck because I don’t have much experience with networking.
I’m using a Dualstack-Lite connection instead of the standard one, and I’m connected to a TP-Link C6 Gen2 router directly via my ISP. I can’t enable bridge mode through an update, though Vodafone does support it on their station modems. Plus, I have a Pi-Hole adblocker running on my Pi, connected to the router with a DNS server I set up.
Can I connect to my Pi from outside my network without buying new equipment or using tools like portmapper? Thanks in advance!
You're dual-nat, which means you can either configure your TP-Link as an access point and let the ISP gateway handle routing, or route specific ports through the ISP gateway to your TP-Link and then forward your Raspberry Pi from the TP-Link.
You have limited options with the ISP router. Consider alternative methods or contact support for further assistance.
ZeroTier offers a peer-to-peer VPN solution that enhances every connected device with a virtual network interface. It employs "UDP-hole punching" eliminating the requirement for port forwards. Simply sign up for a free account and install a lightweight app on each device. They connect via their servers, but data flows directly between devices. I haven't tested it in double-NAT setups, though it performed well previously. ZeroTier guide:
