Enhikari V6 Plus (aka MAP-E) with Banana Pi R4

[kenneyd]

First of all thanks to @fakemanhk for sharing this awesome guide to get everything working with OpenWRT. I wanted to share my own experience with my hardware/ ISP.

I moved from Nuro's G10T plan (awful service, they give you a /64, they lock you in for three years, they're dropping dual stack in favor of MAP-E, and they won't let you use your own hardware with it), to enHikari's v6プラス plan. EnHikari gave me a 10G-EPON ONU, a /56 prefix address, and I temporarily rented their wifi router box, the NTT XG-100NE, to confirm my V6 prefix, test the connection, etc.

For following this guide I used a BananaPi R4 I bought from aliexpress, that was set up with OpenWrt 24.10.0-rc3 (mainline version, not the one provided by BananaPi), and basically everything worked right away. I did have to enable the SLAAC based DHCP server so that android devices on my LAN would get their v6 address properly, which had the effect of the "Active DHCPv6 Leases" being empty (I think I saw this mentioned in another discussion as well).

My only hiccups were finding that the BPI-R4 doesn't support my 10GTek SFP+ module (the 10G-EPON unit uses RJ45 only), but luckily the R4 does support an older Xicom 10G module I had that runs significantly hotter. Then also finding that on the mainline OpenWRT I can't seem to enable hardware offloading (probably this would work in BananaPi's fork of OpenWRT?), which I think is limiting my throughput, as I can't get much above 2gbit/s for up or down on various speedtests sites now.

Anyways, I probably would never have figured all this out on my own, so big thanks for that👍
