Ok, I figured it out. The problem was in my configuration. Address used by GMS can be specified in the UDP section: parameter bind_addr (can be also specified as System property -Dbind.address). Note: contrary to receive_interfaces and send_interfaces the bind_addr does not accept NIC names (like ?eth0?), only addresses.
