Hello all,
I'm having an ARP issue to my VMs on a MacOS X Lion host. The VirtualBox
version is 4.2.6r82870. The VMs are FreeBSD.
In my networking lab, I have this setup:
SRX100 firewall ---- EX2200-C switch ---- Host ---- VMs
I'm trying to do BGP from the cluster to the VMs, but the current step is just
ping. I have assigned IP addresses to all devices temporarily to facilitate
testing, the ultimate goal is L2 across to the VMs.
The problem appears to be ARP replies not reaching the VM.
If anyone has any ideas, I'd definitely appreciate it!
Thanks!
Aaron
IP addresses are:
Firewall: 172.32.2.40/24
EX: 172.32.2.30/24
Mini: 172.32.2.1/24
VM: 172.32.2.50/24
The VM can ping the Mac, the Mac can ping everything, the switch and firewall
can ping everything except the VM. I do get ARP replies (and shows the MAC
addresses are not shared with the host) on the firewall, but not on the VM (VM
only receives ARP entries for the Mac). The Mac receives ARP entries for all
other devices (as expected). The ethernet-switching table on the switch
contains all devices:
Ethernet-switching table: 3 unicast entries

The NIC in question from "VBoxManage showvminfo":
NIC 3: MAC: 080027F2BC5E, Attachment: Bridged Interface 'vlan1',
Cable connected: on, Trace: off (file: none), Type: 82540EM, Reported speed: 0
Mbps, Boot priority: 0, Promisc Policy: allow-all, Bandwidth group: none
In the Mac settings, I have it configured as a trunked interface (virtual
interface - VLAN) where it is configured (IPv4) manually with the IP address
and no router:
vlan1: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
options=23<RXCSUM,TXCSUM,TSO4>
ether 3c:07:54:56:8c:61

inet 172.32.2.1 netmask 0xffffff00 broadcast 172.32.2.255
vlan: 501 parent interface: en0
media: autoselect (1000baseT <full-duplex,flow-control>)
status: active
And IPv4 forwarding is enabled:
% sysctl -a | grep forward
net.inet.ip.forwarding: 1
net.inet6.ip6.forwarding: 1
