2. Topics 1.Security options and settings 2.Layer 2 vs. Layer 3 connection types 3.Advanced network and routing options 4.Local connections 5.Offline mode

3. Lock security options – Admin password The most important one! The admin user can change all the security settings in the Lock, so the password should be changed from the default

4. Lock security options – MAC/IP filter Settings -> Industry settings -> Limit LAN traffic to certain MAC or IP addresses Allowed targets can be specified either using MAC address or IP address Useful especially in mode A

5. Lock security options – “Do not enter” sign Prevents new connections towards the Key from Lock’s LAN and other connected devices Enabled by default and changeable in Edit Tosibox devices

6. Lock security options – Prevent traffic between Sub Locks Used for isolating Sub Lock networks from each other Devices in each Sub Lock network can only access the “main” Lock’s LAN and the Internet, but not devices behind other Sub Locks Helps also performance-wise because it reduces the broadcast traffic that would “leak” between the VPN connections

7. Different connection types Layer 2 – bridged, site-to-site Creates a virtual network interface that appears to be residing in the remote network Can be thought of as having a really long ethernet cable to the remote network Each remote user gets its own address from the remote network Works on the data link layer (MAC) Layer 3 – routed, point-to-point Tunnel end points have private addresses Data is routed to the remote network via the remote end of the tunnel Traffic in the remote network appears to be coming from the Lock device – no additional addresses need to be allocated Works on the network layer (Internet Protocol)

8. Changing the connection type The default connection type is Layer 2 for Key-Lock connections Layer 3 for Key-Central Lock connections and Mobile Clients The connection type can be changed in Lock’s web UI by clicking Edit Tosibox devices

9. Advanced network options – Routing Key users’ Internet connection through Lock Similar to traditional corporate VPN setups Usually slows down the Internet access a bit Can be useful for providing access to office/corporate network resources (via WAN) when Lock is deployed in mode B Or forcing all traffic to go through the company’s proxy or firewall

10. Advanced network options – Access to hosts through WAN Used for providing access to only selected devices outside Lock’s WAN connection. Settings -> Industry settings Other traffic (e.g. Internet) is not routed via the Lock

11. Advanced network options – Static routes Low-level configuration interface for more complex and rare cases Needed e.g. if there are multiple routers in the LAN providing access to different destinations Static routes are pushed also to Key users’ computers - requires Layer 3 connection Configuration at Network -> Static routes

12. Local connections TOSIBOX Key periodically sends out messages in the local networks (LANs) to discover Locks or Central Locks When a connection is requested to a Lock/Central Lock located in the same LAN, a direct connection is made locally, without MatchMaking service

13. Offline mode It is also possible to disable Internet access in the Lock device so that only local connections are allowed (so-called Offline mode). The administrator can choose to block either: All Internet access: both inbound VPN connections and outbound Internet access from LAN is blocked VPN access from Internet (inbound) A temporary exception (timer) can be defined for both, e.g. to allow a technician to get remote access for one hour to perform maintenance work
