We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.

Hi team,

Im a newbie when it comes to cisco. Can any tell me a step by step simple port forward command.starting from conf t.

Newbie,
 
Your question is pretty nebulous, OP.

To simply answer your question, there's really no "port forward" in the conventional sense like a home router would.

In the real enterprise world, you generally achieve "port forwarding" by way of combining two concepts: network address translation (NAT) and access control lists (ACL).

ACL defines permit or deny statements based on various criteria, such as source IP, destination IP, source port, destination port, and also protocol.

NAT is what determines which address is being translated. Example:

Your public IP address is 11.11.11.11, and your internal web server is 192.168.1.100. You would create an inbound NAT rule that would permit traffic to that web server based off the ACL while changing the destination IP address.

If you are this new to the Cisco environment, I think you have jumped into the deep end and are doing yourself a great disservice and making your learning experience much more difficult than it needs to be.

Also, please answer above poster's question.
