Dual-stack IPV4/IPV6 cellular connection help?
-
I have a Huawei E3372H-320 USB-stick. I can place it into a PPP-mode with usb_modeswitch and I can get it to connect to my ISP, but the interface only gets an IPv4-address. No matter what I do, I just can't get IPv6 working and I have no idea what I am doing wrong.
The log for PPP says the following regarding IPv6:
[opt2_link0] LCP: rec'd Protocol Reject #1 (Opened) [opt2_link0] LCP: protocol IPV6CP was rejectedIPv4 is CGNATed, but with the stick in PPP-mode, I should be getting a full, routed IPv6 /64-prefix from my ISP.
Before you ask, no, I don't know what I'm doing. I have never used any modem-stuff before, let alone cellular modems. I am fully aware that I am not providing all the details one might want for helping me, but....well, I don't know what details I should provide or how to obtain them!

Does it require PPP? I often tether my computer or tablet to my phone and it just works, providing both IPv4 via NAT and a /64 IPv6 prefix. Using PPP sounds like a relic from the old cell modem sticks.

@jknott The USB-stick in the default mode is firewalling the traffic, preventing me from listening for connections. The built-in web-UI also doesn't have any option, whatsoever, for port-forwarding.
As for PPP, yeah, it's old. NCM-mode would be faster, but it's apparently not supported by pfSense.
