Hello,
I have a new door entry device that is being installed that has a internal IP address of say 192.168.200.12 that requires port 3001 to be open. The device is reachable via ping and is plugged into a HP Procurve 2910al switch that is connected or supposed to be connected to the the server for the KeyScan software at 192.168.200.13 but even with the TCP/UDP ports opened up on port 3001 the server at 200.13 it can't communicate with the device at 200.12 on the required port of 3001.
Ironically I ran Zenmap to see if the port was open and it's not even registering the port as being open.
I'm doubtful it's our Sonicwalls since this is a internal address; we are running a 32 server Windows Server 2008 R2 network that is running perfectly fine.
What could I do to allow this device to communicate with the server even if the firewall is disabled or has holes poked into it?
