We currently need public IP addresses in PSE-B for testing Porabilling master and slave servers and PortaSIP server.

VTX provides us a range of 16 IP addresses 212.147.8.96/28 in PSE-A.

We divided this range into two ranges of 8 IP addresses 212.147.8.96/29 and 212.147.8.104/29 for using in PSE-A and PSE-B respectively.

Assignment of IP addresses in the first range:

212.147.8.96 is the address zero of the range (cannot be assigned to a host)

212.147.8.97 reserved by VTX (cannot be used)

212.147.8.98 is the LAN interface of the VTX router

212.147.8.99 is the NAT router of office (192.168.1.2 from the side of the office LAN)

212.147.8.100 is the NAT router of test SIP phones

212.147.8.101 is going to be the gateway for routing the 8 IP addresses to PSE-B

212.147.8.102 is free

212.147.8.103 is the broadcast address (cannot be assigned to a host)

Assignment of IP addresses in the second range:

212.147.8.104 is the address zero of the range (cannot be assigned to a host)

212.147.8.105 is the address of the router to be installed in PSE-B

212.147.8.106 is free

212.147.8.107 is free

212.147.8.108 is free

212.147.8.109 is free

212.147.8.110 is free

212.147.8.111 is the broadcast address (cannot be assigned to a host)

The diagram below shows the designed configuration for routing of public IP addresses. The boxes are clickable. Gray boxes are non-NAT routers to be installed for the current configuration. Routing indications are in red.
