flag to disable local networking scans #318

Closed Lusitaniae closed 1 month ago

Lusitaniae commented 1 month ago

We're running servers in Hetzner and every time we install innernet it triggers a netscan alert on hetzner which requires manual intervention

We'd like to have a flag to disable such behavior because anyway a lot of providers don't offer separate internal routing between nodes

as a work around we'll implement a firewall rule preventing outgoing connections to 51820 on udp

    - 10.0.0.0/8
    - 172.16.0.0/12
    - 192.168.0.0/16

hetzner emails looks like:
