no network access in /etc/network/if-up.d script
I have a raspberry pi behind a NAT and a remote virtual server.
I want to be able to access the pi via remote shell from outside.
To achieve this I created an executable file /etc/network/if-up.d/ssh_tunnel on the pi containing
sudo -u myname ssh -fCNR *:2222:localhost:22 myname@1.2.3.4
While this command works, when executed as root from the command line, it doesn't work on startup.
Redirecting stderr to a file gives me
ssh: connect to host 1.2.3.4 port 22: Network is unreachable
What could I do better?

The Script needs to be run after dhcp is finished, most likely the module you want is dhcpcd. Another option would be to configure a static IP on your Pi.
