To connect the Client to the Server behind NAT, do the following:

1. Set the router public IP address (see Network settings utility).

   The router public IP address should be static.

   

2. On the router, forward the gRPC API 20109 port to the internal IP address of the Server port 20109.

3. Launch the Client and specify the router external IP address and the Server external base port in the connection settings (see Starting the Axxon One Client).
   

   When connecting the Client from an external network, only those Servers that have access to the external network will be available in the Axxon-domain configuration (see Consolidating the Servers from different networks into Axxon-domain).

   
   

Example.

To connect the Client to the Servers behind NAT, do the following:

1. From one of the Servers, forward port 20109 to the router public IP address.
2. On the router, configure the forwarding of:
   1. The router port 20109 to the internal IP address of the Server port 20109.
3. When connecting the Client, enter the router public IP address and port 20109.
