Standalone SIParator, with SIP server on the outside

The simplest SIP scenario is when the SIP server is managed by someone else, and the SIParator SIP function is only used to traverse NAT.

Note that the SIParator must have a public (non-NATed) IP address for the SIP signaling to work correctly. The following is a sample standalone network structure.

The network structure is shown below

Configure InGate SIParator 4.6.1

Once the IP address is set to InGate SIParator, you can access it from web browser by it IP (, example of selected IP address in the network structure shown before). Please follow the following steps once the webpage is open.

1. Set SIParator Type

Set the SIParator Type as “standalone” under [Basic Configuration]>[SIParator Type]

2. Network Configuration

Ethernet interface configuration
Using standalone configuration, the SIParator is connected to the outside on one interface and your internal networks on the others. In the shown example, “” is used to internal networks, which is set on Ethernet 0, and “” is SIParator’s public IP address to connect to the outside, which is set on Ethernet 1.

Ethernet settings can be done either at [Network] >[Eth0]/[Eth1] or at [Network]>[All interfaces]

  • Set the corresponding ethernet interface on
  • Configure ethernet IP address, Netmask, example shown below

Set default gateways
At [Network]>[Default Gateways]

Define Networks and Computers
At [Network]>[Networks and Computers]

3. SIP Configuration

Enable SIP Module
Enable SIP Module at [SIP Services]>[Basic]

Define local domains handled by SIParator
At [SIP Traffic] > [User Database]
Either domain name or IP address can be used.

Enter a Proxy rule for processing internal network SIP requests
At [SIP Traffic]>[Filtering]

4. Apply Configuration

At [Administration]>[Save/Load Configuration]

Save Configuration

Save configuration to make it in use.

Configure User Clients

The SIP user clients should have (the SIParator’s internal IP address) as their outgoing SIP proxy. And Brekek SIP server’s global IP address as their SIP proxy.
