Since your pinging from the same router that this IP
resides on the access-list doesn't come into play.
Traffic flowing through that interface will be looked
at against the access-list but not traffic sourced
from the router, unless you set up a local policy
route.
If you have a static route routing traffic destined to
100.200.3.0 to 192.168.3.1 this will cause what your
seeing and NAT could effect it as well.
Hows the NAT configured and what are you permitting to
be NAT'd? If your permitting 100.200.3.x and your
outside NAT pool is 192.168.3.x then this could be the
problem as well.
Need to know more about the config.
