Sometimes you don’t have the possibility to use the Lock default IP address range, e.g. when you need to connect to a device located in an established customer network. For one location this is generally not a problem, you just change the Lock IP address range on LAN side to match customer network.
However, you may encounter the same IP address range at another customer, in which case you could only connect to one location at a time. This is not feasible in cases where you need continuous monitoring of your systems at all your remote locations. The solution is the 1:1 NAT on Lock.
1:1 NAT means that the device IP addresses on LAN side of the Lock are directly mapped to NAT IP addresses at Key (or Central Lock) side.
NAT can be set on Lock Network > LAN settings
For example, you have defined
- Lock LAN IP as 10.15.6.1 with netmask of 255.255.255.0 and
- device on that network is 10.15.6.2
Then you simply set the NAT on and either let the Lock designate the NAT IP network address or manually define one, e.g. 10.1.1.0.
From Key side, you can then access the Lock user interface with the NAT IP 10.1.1.1 and the device with IP 10.1.1.2
Continue setting up the same LAN IP and netmask to other Locks, enabling NAT and taking care the NAT IP is from different network for all Locks. You will end up having a setup similar to the example network above where
- all your Locks have the same LAN IP settings
- all devices have the same IP address defined
- Devices on Lock LAN communicate using this IP address range locally
- From Key side you can be connected to all sites simultaneously and communicate to remote locations using NAT addresses
