Success! My Framework-Fedora system can finally go online while using IVPN.
It took me some time to get get back. Thanks for all the replies.
I ended up buying a new router - which was suggested to me by IVPN staff. After lots of (additional) frustration I got it to work.
For anyone who cares to know how I made it to work, read as follows.
Initially I put the Netgear M1 in ‘IP passthrough’ mode to turn it into modem only and make the new router (Netgear RAX30) in charge of NAT functionality. But the router didn’t get working internet access (it works for a second, just enough to get IP info from the ISP, and then it flunks).
As you probably guessed, my ISP offers only 4G which means I’m behind their CGNAT. From what I learned online, this may be the cause for IP passthrough not working.
I got the connection working by the following changes:
- Changed the APN of my ISP to a more open (and less secure) NAT
- they say I will receive real IP, all though not static (24hr renewal cycle). But so far, I didn’t. I think if I did, the IP passthrough would work.
- Kept the M1 in regular (modem + router / NAT) mode but setup for port-forward by:
- Turning off DDNS
- Enabling DMZ for a single IP (pointing to the new router).
- Modem M1 IP: 192.168.1.1
- Router RAX30 IP: 192.168.1.2
- Setup the routers internet connection manually by:
- IP: 192.168.1.2
- Subnet mask: 255.255.255.0
- Gateway IP: 192.168.1.1
- DNS: the ISP’s DNS
- The LAN addresses: IP Router 10.0.0.1 DHCP Range 10.0.0.20 - 10.0.0.256
I guess this may be a triple NAT situation, far from ideal. But, I did get it to work - at last!
