Here is something odd. i can ping and trace to the dmz with no problem. does anyone have an insight on this?

Hi;
First, Ia don't see ACL inside_outbound_nat0_acl defined.
If you want that internal users allow to access dmz, I don't necesary static (inside,dmz) zzz.zzz.zzz.zzz yyy.yyy.yyy.yyy netmask 255.255.255.255 0 0

the log shows this when trying to ftp
Deny TCP (no connection) from 207.250.100.149/21 to 10.8.15.10/54278 flags SYN ACK on interface dmz
looks like some kind of translation is missing, but i cant make heads or tails of it....anyone see the issue?
