Configure a ASA for Telnet on port 25
Posted on 2010-08-23
OK.. In know I am doing this right but I could be wrong.
I have a Cisco ASA 5510
On the Network I have an Exchange Server with the Internal IP address of 192.168.151.42. This is a New Server that I am working on adding to the network. Our Spam Filtering service uses port 25 to telnet on. What I need to do is telnet to the Firewall and using NAT pass on the Data to the Exchange server. So if someone could do me a favor and give me all the commands I would have to enter to ghet this completed.
I need the following:
NAT for the Exchange server is IP Address 192.168.151.42 from an External IP 188.8.131.52 (Only an Example not real IP address)
Open ports 80,25,443,110
Allow Telnet on port 25.
Please help me out, cause it's driving me nuts.
