FORMERR is strange. Generally speaking, you should not be seeing FORMERR
in queries between 2 different BIND instances.

It's looking increasingly to me like a bad NAT/PAT device, mangling your
packets. Maybe it doesn't understand EDNS0 (?) My next step would
probably be to run a packet trace/capture, although, on the off-chance
that it's EDNS0-related, you might try turning that off and see if it
makes a difference.
