Allowing Specific Port from External IP to internal host on Cisco ASA 5505
Posted on 2011-02-16
I have an external ip i'm publishing to an internal ip using port 2022. Its pretty straight forward, however, i'm using asdm to do it. I simply create the public server, assign the internal and external ip, create a service and assign tcp 2022 to it and asdm does the rest. I have successfully published smtp, http, etc to other hosts within so I know how to do this. Once i publish and save, the external device is still not able to connect through port 2022. In looking at the logs, it tells me Deny tcp src outside:<my outside ip here>/36715 dst inside:10.0.0.248/2022 by access-group "PUBLIC-INCOMING" [0x0, 0x0].
Why would public-incoming be denying if it specifically is allowing in my access rule. Help!!
