[Solved] Host only adapter - can't connect

Posted: 27. Nov 2017, 15:46

Hi,
I've just set host-only adapter on my host ubuntu and trying to connect to my guest x86-64 linux based software router - IPFire.
I can not ping from ubuntu to IPfire and from IPFire to ubuntu.
How could I diagnose and fix this?

Code: Select all

root@ipfire:~$ ping 192.168.56.1
PING 192.168.56.1 (192.168.56.1) 56(84) bytes of data.
From 192.168.56.101 icmp_seq=9 Destination Host Unreachable

ela@akacja:~$ ping 192.168.56.101

Ok.
Ping from host to guest and from guest to host is working now.
The cause of the issue was probably the bridge I've made on guest side. I've bridged green+ eth3 network interfaces.
Without the bridge ping works fine,
I have to modify settings on guest side to have eth3 and existing LAN (green0) as single network...
