[libvirt-users] ICMP into guest not "working"

[David Lane]

Good afternoon.

I have a RHEL6 host, running RHEL 3.8 as a guest.  The NIC is bridged.  From
the guest, I can ping successfully to a variety of network devices.  From
the host, I can ping successfully to a variety of network devices AND the
guest OS.  But from my workstation, I can only ping the HOST, not the
guest.  And it looks like the packets are being discarded.

IPtables is NOT enabled on either the guest or the host (our application
does not support iptables filtering - go figure).

I am seeing lots of documentation for enabling outbound pings from guest,
but very little about enabling inbound pings.  And again, our software
relies on pings for parts of its operations and validations.

Any clues as to what I might have missed?

Thanks,

DAVID
