Telegraf plugin: set source inteface

[Mechanix]

I have a Opnsense instance running behind a WireGuard Tunnel. The issue is, that telegraf binds automatically to WG0 interface which is not part of the encrypted traffic and gets dropped.
Is there a way to set the local_address mentioned in the release notes: https://docs.influxdata.com/telegraf/v1/release-notes/

Thanks

P.S.

I'm using:
os-telegraf (installed)   1.12.13

https://github.com/influxdata/telegraf/tree/master/plugins/outputs/influxdb_v2

You can create a default config by using "telegraf config >/tmp/telegraf.conf". It shows:

I assume you must specify an IP.

However, there is no provision in the OpnSense UI to specify that, so you can open a feature request on Github to add an input.

Thanks for your reply. Need to figure out why I can' t bind the address tough:

E! [agent] Error writing to outputs.influxdb_v2: Post "http://xxxx.2:8086/api/v2/write?bucket=opnsense&org=Proxmox": dial tcp yyy.1:0->xxx.2:8086: bind: can't assign requested address
Edit: got it working . Thanks
