Just a few quick questions, i am a bit concerned over security and I really dont know how much I have to worry about at this point. The best way for me to explain this is to explain my setup and then you can let me know if it is insecure or not.
I currently have a server, it is not external facing and it does not need to be, it basically runs software for IP camera recordings and does some printer and file sharing, nothing heavy.
I have two IP cameras that until now where also not external facing. My ISP will not provide me with a static IP address so I have instead signed up with noip.com which is a DDNS for those that havent used it. The agent is installed on my server checking regularly for any changes in my public facing IP address.
I have a Draytek Router that I have setup Port Redirection under NAT so that basically the external facing port to access the camera is a random one (59621 for example) and when you go to my DDNS address with the correct port, the Draytek redirects it to the port and IP address internally which is different (81 with 192.168.0.248 currently).
I hope that all makes sense...
Are there any security risks involved with this? I litterally have the web interface for the camera at the IP address that NAT takes you to, the camera interface is also protected with an additional username and password before you can view or do anything with the camera.
Additionally, are there any online free tools that i can use that will scan ports etc and check for any risks in my network?
Thanks in advance!
