Re: [tlug] Speed up SSH/SFTP/Git/rsync/etc. on NTT fiber

Hello TLUG,

This is the case for me as well, although it seems to somehow depend on the location. I used to live in a place where it was not throttled at all, then at the next place it was outright blocked. It seems to also be the case for Hikari Cross connections.

Additionally, Wireguard uses AF41 on handshake packets, which caused my tunnels to never establish connections. Since this was hardcoded and not configurable, I had to filter the packets and rewrite the DSCP at nftables on my router box.

(Speaking of the router it also has the problem that the MAP-T implementation hacked on nftables maps the port suboptimally since the range is non continuous... A workaround I could think of is to first translate to a continuous range of 240 ports, and then statically map each 16 ports to the desired ports in a separate network namespace or something, but I haven't got around to actually implement that.)

I was surprised when I found out this selective behavior since prior to that I used to think that Flets IPoE was fairly good at being a dumb pipe.

I was not aware of the post by Asahi Lina and as an Asahi Linux user it was interesting to see her encounter a very local problem that I was familiar with.

Best,
