Hi all,
I am runnning an ASA5510, with interface config
Inside: 192.168.0.254/24
Outside: 123.123.123.241/28
DMZ: 123.123.123.238/28
that mean usable IP range in DMZ is 123.123.123.225-238
usable IP range in Outside is
123.123.123.241-254
123.123.123.254 is gateway IP of ISP.
The problem is,
ISP gave us 64IP 123.123.123.192-255, but we now only use 32. I wanna make use of it by change the config of existing firewall.
NEW setting as below
Inside: 192.168.0.254/24
Outside: 123.123.123.241/27
DMZ: 123.123.123.222/27
Gateway is unchanged
that mean usable IP range in DMZ now is 123.123.123.193-222
usable IP range in Outside is
123.123.123.225-254
But once I change it, server behind inside interface can surf internet,
but both server behind DMZ and outside cannot.
and ASA show followling error message
3|Dec 17 2007 17:04:04|710003: UDP access denied by ACL from 123.123.123.244/1158 to outside:202.66.92.241/53

Firstly, I think it may be ACL problem , but even I use very simple config as below, same problem still occur,
