[Touch-packages] [Bug 1500992] Re: Provide script to enable IP forwarding
This approach doesn't work after all, see https://github.com/systemd/systemd/issues/1411#issuecomment-144975442 So changing back to the original title. ** Summary changed: - Provide script to enable IP forwarding + networkd: Don't reset forwarding unless told to do so in config -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1500992 Title: networkd: Don't reset forwarding unless told to do so in config Status in systemd package in Ubuntu: In Progress Bug description: It's been reported by several LXC users that systemd-networkd will turn off per-interface forwarding for all network interfaces when it starts. Presumably upstream expects users to go and manually edit their config to allow it when needed. This breaks LXC, libvirt, ... anything which ships a bridge that then NAT or route outgoing traffic. Requiring the user to do the config change would be a massive regression in user friendliness and having lxc, libvirt, ... do it for the user would be a policy violation. As a result, I'd recommend we patch systemd to not interfere with forwarding unless explicitly configured by the user. This will allow all our existing scripts to keep setting things up themselves and have it all run fine.

[Touch-packages] [Bug 1500992] Re: Provide script to enable IP forwarding
It is much simpler to just set
/proc/sys/net/ipv{4,6}/conf/all/forwarding to 1, as that updates all
conf/iface/forwarding and /proc/sys/net/ipv4/ip_forward. I. e. we just
need
for f in /proc/sys/net/ipv*/conf/all/forwarding; do
echo 1 > $f
done

Title:
Provide script to enable IP forwarding
Status in systemd package in Ubuntu:
In Progress
Bug description:
It's been reported by several LXC users that systemd-networkd will
turn off per-interface forwarding for all network interfaces when it
starts.
Presumably upstream expects users to go and manually edit their config
to allow it when needed.
This breaks LXC, libvirt, ... anything which ships a bridge that then
NAT or route outgoing traffic. Requiring the user to do the config
change would be a massive regression in user friendliness and having
lxc, libvirt, ... do it for the user would be a policy violation.
As a result, I'd recommend we patch systemd to not interfere with
forwarding unless explicitly configured by the user. This will allow
all our existing scripts to keep setting things up themselves and have
it all run fine.
