Very strange network issue

[mtomas]

I’ve purchased a data sim as there is 4G/5G in the area and it’s better than FTTC.

I  can connect to the internet using a Huawei 5G/4G CPE Pro Win 2 H312-371. This device then connects to a Linksys Velop Pro WiFi 6E Mesh System via ethernet. The Linksys however cannot see the internet from the Huawei router.

I’ve tested the Linksys and it works with a Vodafone sim in the CPE Pro. It also works when I use the EE sim with an older router. The combination of the CPE Pro and Linksys with the EE sim is just not working.

(The only way I could get any sort of connection through that combination was by setting the IPv6 to pass-through, not ideal.)

Please help!

After some trial and error as well as reading some other posts re dual stack I changed the Huawei to only connect use IPv4. This seems have fixed it. I’m not a network specialist so not sure if will have any downstream effect on performance but it seems to be working so far.
