Modifying port for Netclient prior to Netmaker Install ?

[gigadjo]

Hello, and thanks for Netmaker, it's a great tool !

Tho, i've been using it for a short time, i came across a problem : i try to connect to Netmaker from a filtered network, stateful firewall rules won't allow connecting from some network on some ports (in short).

Thus, some ports, are actually not filtered, because of probably 'internal use case'. I tried to set a simple Wireguard connexion on those ports, and it works very well.

I Found this parameter laying in https://github.com/gravitl/netclient/blob/develop/config/config.go

DefaultListenPort = 51821
// DefaultMTU default MTU for wireguard
DefaultMTU = 1420

It's then copied to /etc/netclient/netclient.yml

os: linux
interface: netmaker
debug: false
listenport: 51821
wg_public_listen_port: 51821
mtu: 1420

Is there a way, i did not figure out, how to pass this as a parameter during install process ?
As it seem to be read from file, even setting the value as an env_var may not work properly :-)

One can still use after install, or even afterward :

nmctl host update <host_id> --listen_port

As far as you disable / re-enable clients, their WireGuard config is rewritten, i don't know how it works for netclients 'clients' :-)

But it would be nice to be able to choose the port used from the start :-)

Thanks again for making such a great tool Open Source, best regards,

/joen

@gigadjo , How you defined the config file? As I tested with,

host:
    listenport: 51825

After the installation, the port listens on 51825

tcp6 0 0 :::51825 :::* LISTEN

test done in v0.21.2
