6. Your problem:

Thank you for your support in advance.

We are attempting to configure two servers for Brekeke SIP/PBX failover. We have read the wiki post thoroughly and have been working with a Brekeke distributor and have been unable to come to an accurate configuration.

Each server has two NICs (Network Interface Cards):

NIC1 is directly connected to a public network. This is the network used by clients to attached their UA devices and for SIP trunk carries to terminate/originate calls from.

NIC2 is an interconnection directly between servers used for the Brekeke failover heartbeat/mirror connection.

In particular:

Server 1 Configuration->

NIC1 IP: x.x.x.2
NIC1 Subnet: 255.255.255.192
NIC1 Gateway: x.x.x.1

x.x.x represents a public network address space given to us by our ISP.

NIC2 IP: 192.168.200.10
NIC2 Subnet: 255.255.255.0

Server 2 Configuration->

NIC1 IP: Disabled

x.x.x represents a public network address space given to us by our ISP.

NIC2 IP: 192.168.200.20
NIC2 Subnet: 255.255.255.0

Note that UA devices are terminated to x.x.x.2 and this is the IP address that is moved from Server1 to Server2 in case of a fail over situation.


My questions are:

1) Is this configuration correct/accurate/ideal?

2) Can I change the configuration as described below so that Server2 is accessible via the public network at all times:

Server 1 Configuration->

NIC1 IP: x.x.x.3
NIC1 Additional IP: x.x.x.2
NIC1 Subnet: 255.255.255.192
NIC1 Gateway: x.x.x.1

x.x.x represents a public network address space given to us by our ISP.

NIC2 IP: 192.168.200.10
NIC2 Subnet: 255.255.255.0

Server 2 Configuration->

NIC1 IP: x.x.x.4
NIC1 Subnet: 255.255.255.192
NIC1 Gateway: x.x.x.1

x.x.x represents a public network address space given to us by our ISP.

NIC2 IP: 192.168.200.20
NIC2 Subnet: 255.255.255.0

Note that UA devices are terminated to x.x.x.2 and this is the IP address that is moved from Server1 to Server2 in case of a fail over situation.

This is the configuration that makes most sense to me so that both servers are always accessible via the public address space and the x.x.x.2 public IP address is what moves from server to server during a failover situation.

You feedback, support and expertise is much appreciated in this matter.

Thank you in advance.
