Interface with 2 IPs ?!?!

[cezarq]

My network interface is showing 2 differents IPs addresses... Why and how can I fix it?
The correct IP is 192.168.1.3/24 and it is static.

Edit em0 under 'Network->Interfaces' and make sure you don't have an alias defined there.

Do you have any jails or plugins running.

Those are creating alias when vimage is not set.

There is one jail running, but with a different IP.

[pasiz]

is vimage enabled on jail?

 

[pasiz]

Ahh, card is in promiscuous mode, must be related to your vm image networking...

 

[cezarq]

is vimage enabled on jail?

It was enabled... I just unchecked... Do I have to restart the server to check if the IP is still set?

 

[pasiz]

I think it belongs to your vm settings, how network is routed. See also your vm config about network.

vmnic0 is the interface, could you show that?

Strange... what is the ip of the vm?

Host = 192.168.1.250
FreeNAS = 192.168.1.3

Could you determine anything via nmap?

The both IP (.3 and .212) are up and working.... Wtf?!?!

 

[pasiz]

But if you nmap full port range, could you make assumption of the services offered

So you have http, https and snmp in listen. Have you configured something via console?
