I'm using VirtualBox 5.0.10 on Ubuntu Server 14.04.3.
I configured bridged networking for VM with Ubuntu, but it seems VirtualBox isn't routing packets between host and VM.
I can't ping host from VM and vice versa, but I can ping host from VM using arping:
arping XX.XX.XX.11
ARPING XX.XX.XX.11
60 bytes from 08:60:6e:68:16:86 (XX.XX.XX.11): index=0 time=7.739 msec
60 bytes from 08:60:6e:68:16:86 (XX.XX.XX.11): index=1 time=3.419 msec
But I can't arping default router form VM.
That means l2 networking works for host, but not for all network.
Please help, because I used bridged network before many times, but this server drives me crazy
P.S iptables rules are cleared, net.ipv4.ip_forward=1 on host enabled
