The PBX is connected to a local network and receives the IP address that is also used to access the integrated web server for configuration.
*Please refer to the PBX Instruction for instructions about how to set up the network connection.
The PBX connects different communication nets with each other.

Only COMtrexx Business: By upgrading with a NET module, there are now two networks with different IP address ranges available.
*Further help under Network interface (second)
Using the network, configuration data provided by the PBX is tranferred to the connected IP telephones and DECT base stations.
*Further help under Provisioning
For a CTI solution, the PBX can be connected to a local network existing of CTI server and CTI clients.

IP block- and allowlist
If traffic from a particular IP address is judged as being too high - and therefore, probably malicious - this IP address is blocked. This means that accesses from this IP address to the PBX are initially prevented for one minute (single block by block time). The administrator is informed about the block by a system message.
*Further help under System messages
During the block time the PBX continues to monitor the traffic from this IP address. If the traffic from this IP address to the PBX continues to be too high, the single block time is extended (block time restarts).
If the number of attacks from IP addresses over the Internet exceeds a threshold, all traffic outside of the local network is blocked (global block). The local network is the network configured for the CPU.
The administrator must then put in place appropriate measures to protect the PBX within its infrastructure (e.g. using routers or bridges).
*Note: The global block deletes all further entries (single blocks) from the blocklist.
*Note: When opening the page, it first shows the status which is automatically updated every 30 seconds.
*Important: All the entries in the blocklists are deleted when you reboot the PBX.
Network-based access attempts, such as the number of data packets per second or SIP authentication failures are monitored and evaluated.
IPv6 Mode
If IPv6 is configured, an IP address complying with version 6 of the Internet protocol can be assigned to the PBX. Due to the greater length of IPv6 addresses (eight blocks with four digits each, example: 3001:00FF:ABC0:0EAC:0001:0000:0000:000F), IPv6 offers a greater number of available IP addresses than version 4 of the Internet protocol (IPv4).
