Have you tried '-i any'?
tcpdump man page says:
-i Listen on interface. If unspecified, tcpdump searches the
system interface list for the lowest num-
bered, configured up interface (excluding loopback). Ties are
broken by choosing the earliest match.
On Linux systems with 2.2 or later kernels, an interface
argument of ``any'' can be used to capture
packets from all interfaces. Note that captures on the
``any'' device will not be done in promiscuous
mode.
