ISP Configuration in case of TATA (Unmanaged ILL)

ISP Configuration in case of TATA (Useful for Indian Customers willing to configure an unmanaged TATA ILL)

 

** This is useful in case you are not provided with a MUX or a ROUTER along with the Internet Link form the ISP**

 

If you are a customer willing to configure an unmanaged TATA ISP where you are provided with a LAN IP POOL and WAN IP POOL from the ISP end then follow the below steps as mentioned:

Considerations:

  1. WAN IP AT THE CUSTOMER END: 1.1.1.1/30
  2. WAN IP AT THE ISP END (This is the ISP Gateway): 1.1.1.2/30
  3. LAN IP POOL GIVEN TO THE CUSTOMER BY THE ISP: 3.3.3.0/29

 

Configure as following:

  1. Configure the WAN interface with 1.1.1/30 as its IP address.
  2. Create two static routes:
  • Route Name: TATA_WAN, Destination: 0.0.0.0/0, Interface: WAN Interface, Next Hop: 1.1.2/32, Metric: 10
  • Route Name: TATA_LAN, Destination: 3.3.1/32 (use any IP from the LAN Pool as the LAN Gateway), Interface: WAN interface, Next Hop: 1.1.1.2/32, Metric: 10.
  1. Create a source NAT for Internet access:
  • Provide a useful name
  • Select source zone as LAN
  • Select Destination zone as WAN
  • Interface as the WAN interface
  • Source Translation, dynamic IP/port, Address type: Translated address: 3.3.2/32
  1. Create a policy rule as required.

Check your Public IP as you should see 3.3.3.2 as your public IP

 

Hope this is helpful.

 

Cheers !!
