Hi,
I have Mail server in the DMZ zone,and it is natted and the port 25 is opened....with the following command,When I try to telnet the server NATTED ip with the port 25 ,I am getting the blank screen,but no message appears....
static (dmz,outside) tcp 77.68.148.72 smtp 192.168.3.7 smtp netmask 255.255.255.255
Where as the same server is natted with the same public IP with port 110,in that case when I telnet to the server with the port number 110,I am getting connected and I am able to see the message from teh server.
Please help me to resolve this issue.
Regards,
