Public Port - Port forwarding 1-65000

So this seems like a very bad idea to me. But I am not the sharpest one when it comes to port forwarding. This was done from a consultant for our company. Camera system needs to be view able from outside network and is not meraki. But currently settings are like below.

 

Uplink: Both

Protocol:TCP

Public Port: 1-65000

Local Port: 80

Allowed remote IP's: any

 

Cameras are accessed my multiple people who are remote and travel a lot, specifying IP's is not practical and they are against VPN to do this because some are note domain users.

 

My questions are around Public port. With it like this, isn't it a rather large security risk allowing anything going to the public IP on almost any port straight through the firewall? And wouldn't it be directing all the traffic from outside directly to the camera?

Hi @TimBisel

 

I would agree that this wouldn't be my ideal setup, albeit I'm sure it gets the job done...

 

Do they need access to each individual camera externally? Or are they only accessing an NVR that all of the cameras are connected to? If it's the latter, you should only have to specify a single IP for the NVR. You would also want to identify what public port needs to be opened and narrow the exposure to that device. Probably could be found in the configuration of the NVR.

Kind of a big deal

Re: Public Port - Port forwarding 1-65000

At that point you'd be better to do a 1:1 NAT and only let port 80 through.  But if they'd need to NAT any of those other ports to something else it'd be a waste.  Seems lazy to me.  Would be far more secure to only map through the ports it needs.

Thanks guys I am new at company and still need to build the trust in. Was able to convince him to let me trim it down to the one needed port. It connects back to a server so I was able to do it with just one port.
