Hetzner servers connected to same switch - no connection between them

[CyberCr33p]

Both servers are connected to the same switch. If you need a connection between the servers, you have to set a static route on each server (if using DHCP) or change their netmask to /32 (if using static IP configuration). This is necessary as we use the "protected ports" security feature on our switches.

Any idea how to "change their netmask to /32" ?

I tried:

ifconfig_igb0="inet {MY-IP} netmask 255.255.255.255"

but network is not accessible with this setting.

I might be wrong but you could try in hex :

netmask 0xffffffff

To show your routes you can use:

netstat -rn

You might have some issues setting your default gateway. FreeBSD really doesn't want to set a gateway to an address that's outside of the host's IP/netmask range. With a /32 everything is outside of that 'network'.

You might need to resort to setting a gateway like this: route add default -iface igb0 to force it out of igb0.
