Under Ubuntu 20.04 LTS focal
I previously configured a net64 tunnel to use the HE-IPv6 service. Below is my config:
.
├── 50-cloud-init.yaml
└── 51-he-ipv6.yaml
# 50-cloud-init.yaml
network:
version: 2
ethernets:
ens3:
dhcp4: true
match:
macaddress: xx:xx:xx:xx
set-name: ens3
# 51-he-ipv6.yaml
network:
version: 2
tunnels:
he-ipv6:
mode: sit
remote: 74.xx.xx.xx
local: 10.0.0.2
addresses:
- "2001:470:xx:xx::x/64"
gateway6: "2001:470:xx:xx::1"
When I use rclone to copy files, I must specify an exit route of 10.0.0.2 otherwise there will be no speed:
% rclone copy ... # no speed :(
% rclone copy --bind 10.0.0.2 ... # everything work
So should I configure route metric for tunnel?If the answer yes, how?
More Informations:
