Good day everyone. I am successfully running Wireguard on my OPNSense installation. I am wondering why I didn't use it sooner...fast connection, stays on even when my mobile devices lock, and I can access my home network. It is an awesome solution.
I noticed that I can use my Wireguard VPN whenever I'm connected to a WiFi network. However, it doesn't work on cellular. Doing some research, I believe it's because cellular connections use IPV6. (Please let me know if I am correct or not.)
So, looking at my config, I have some idea as to my next steps but could use some confirmation. I am attaching screenshots on my current configuration.
Here's what I'm thinking:
- All of my Firewall rules only point to IPV4. I'm assuming I need to switch these rules to use both IPV4+IPV6.
- Do I need to modify my gateway interfaces settings?
- Currently, my DDNS settings are passing arguments for IPV4. I'm assuming I'll need to have my DDNS pass an IPV6 address. Is that correct?
- What changes do I need to do for my peers to use IPV6?
Thank you in advance.
