I have just installed a new Video Digital Recorder (DVR), for my client, connecting to 8 internal camera's. This new DVR supports access via an iphone app CCTVSP - Lite, outside the internal network.
I have an ASA 5505 Cisco firewall.
I added the following CLI configuration:
access-list DVR extended permit tcp any host 18.104.22.168 eq www
access-list DVR extended permit tcp any host 22.214.171.124 eq 37777
access-group DVR in interface outside
I attempt to see if the port is accessible via www.canyouseeme.org
and receive the following error message:
Error: I could not see your service on port (37777)
I performed a 'logging Monitor 7' to debug and discovered that the TCP request for 37777 was discarded.
I also attempted to access the ASA 5505 via the IE/Chrome web browser. The application just hangs after I input login info. I tried it on an XP/Win 7 pro PC.
What am I doing wrong?
How can I best troubleshoot this situation?
