Sent from my MacBook Pro :) They both have an iphone, apple watch, macbook and are 100% in all the cloud shit | 12:28:30 |
 emily | I might be an Apple user but I still think having a modem in the chain doing nothing at all and not talking to what it thinks it is is absurd :D | 12:28:34 |
| magic_rb | Hey if it works it works | 12:28:56 |
| magic_rb | And tbhch the wifi on the bpi was very unstable last year, so having the ISP router do also wifi was nice | 12:29:21 |
| emily | (it's at least the one cloud ecosystem where you can trivially have full end-to-end encryption of everything even if there's lock-in… pretty much every other normie cloud option is worse for security and data sovereignty) | 12:29:22 |
| emily | (off-topic though of course. I don't use it myself anyway, just for lock-in concerns.) | 12:29:29 |
| magic_rb | Cause that one is reliable actually, even though the chipset is broadcom | 12:29:33 |
| emily | oh, the ISP modem is also a router? I assumed you had WAN → BPI-R4 → ISP modem → ISP router or something, which would just be ridiculous. | 12:29:58 |

| magic_rb | The normal way is isp router -> isp PON | 12:31:03 |
| magic_rb | Its a bit weird cause KPN here send pppoe over fiber which is bizarre | 12:31:29 |
| emily | I think your → is my ← | 12:32:34 |
| emily | but yeah, that makes sense, "I guess". | 12:32:39 |
| emily | yes, here too | 12:32:48 |

I think your → is my ← Yep, symmetry :P | 12:33:22 |
| emily | (almost every provider using the Openreach network uses PPPoE. there are a small handful that do DHCP. this seems to be true invariant of DSL vs. fibre, I guess because the backbone network is the same in both cases.) | 12:33:24 |
| magic_rb | Ill see what freedom does (yes we have a provider called freedom) they use the KPN network, but maybe they dont so funky pppoe over it? Doing wireguard would be cool lmao | 12:34:17 |
| emily | (I expect this is because PPP infrastructure happened earlier and it just stuck. also, because most ISPs are going through one of a handful of wholesale providers who deal directly with Openreach, and I think that PPPoE vs. DHCP is a decision made at at that level, so only providers big enough to deal directly with the network can even make the choice themselves.) | 12:34:43 |
| emily | I would expect if they use the KPN network they don't have a choice about using PPPoE, based on what the landscape looks like here. | 12:35:09 |
| emily | i.e., the PPPoE is going to happen before they get their hands on the traffic, so to speak. | 12:35:20 |
| emily | have you checked whether the network supports mini jumbo frames? Openreach do here, so you can at least get a full 1500 MTU on the resulting link. | 12:35:46 |
| magic_rb | Probably, hopefully ill see on the 10th, im supposed to get fritzbox with a sfp+ pon, which ill try shoving into my bpir4 and see what happens | 12:35:55 |
| emily | (by using an 1508 MTU on the WAN link to offset the PPPoE encap overhead) | 12:36:00 |
| magic_rb | Yeah i do that | 12:36:12 |
| magic_rb | One of the rhings that broke a lot of sites for me, macos assumes 1500, or at least i couldnt get it to cooperate and if then the router would have to fragment things, cloudflare would fail to defragment it somehow | 12:37:05 |
| magic_rb | cache.nixos.org was not working at all when it was fragmenting. I still dont know wtf was up with that | 12:37:33 |
| magic_rb | I actually owe this setup to puck, (not in this room, but i think they should be somewhere in this space), cause i assumed theyd know how to set it up, which they did. I also initially had a bug where the bpi couldnt handle packets smaller than 40 bytes i think, which would break pppoe, now there is a patch at least in franks tree, which pads the frames out to 40 bytes | 12:39:29 |
| emily | I think this probably just means you had stuff configured wrong? | 13:14:49 |
