for some months, our border routers log attempts to connect from the
outside using a source address that is internal to my network. e.g.
Oct 3 06:48:12 r0 7833: Oct 3 06:48:11.267: %FMANFP-6-IPACCESSLOGP: SIP0: fman_fp_image: list serial-in4 denied udp 147.28.0.223(3465) -> 147.28.0.222(53), 1 packet
some days, we see a *lot* of this. anyone else seeing similar?
