>From the ipnat man page:
bimap should really only be used with single IP addresses (x.x.x.x/32).
Bimapping other CIDR ranges will result in unexpected, and possibly ran-
dom mappings into the destination address block.
How hard would it be to overcome this limitation? Ideally anytime
an address mapping like 18.104.22.168/16 -> 22.214.171.124/16
was in place (ie. the address block size was the same), the
mapping would be one to one, leaving the low bits in tact
(ie. 126.96.36.199 -> 188.8.131.52, 184.108.40.206 -> 220.127.116.11).
I sent mail to Darren Reed (listed as ipnat author), but have
not heard back from him yet.
