[SOLVED] OPNsense vtnet has no carrier when connected to Linux bridge without physical connection

[kalleb64]

Hi,

I have configured OPNsense as VM. The DMZ (vtnet3) is mapped to vmbr3, a Linux bridge without physical NIC and without IP address. The IP address of DMZ is 172.16.16.1/24.

I have two other VMs: 2 LMDE6 (faye) guests also mapped to vmbr3. They have the addresses 172.16.16.2/24 and 172.16.16.3/24.
The two LDMEs can ping each other, their interface status is UP.


However, they cannot ping the OPNsense. vtnet3 has the status "no carrier".



Strange enough, netstat counters for incoming packets grow on vtnet3.
[DMZ] (vtnet3) / 172.16.16.1 [LIST] [*]name [B]:[/B] vtnet3 [*]flags [B]:[/B] 0x28963 [*]network [B]:[/B] 172.16.16.0/24 [*]address [B]:[/B] 172.16.16.1 [*]received-packets [B]:[/B] 6584 [*]received-bytes [B]:[/B] 184352 [*]sent-packets [B]:[/B] 0 [*]sent-bytes [B]:[/B] 0 [/LIST]
But because there is no physical whatsoever, FreeBSD considers the interface to be down (whereas Debian can handle this properly)


Questions: is there a way to tell FreeBSD to consider vtnet3 to be up even without "carrier" ?
And yes, I have tried ifconfig vtnet3 up. It does not help nor report any error.

Thanks for your help.
K.

Silly me.
For some reason the interface was initially switched off by proxmox.
Select the Device -> advanced -> uncheck disconnected.
