Hi,

There is nothing to do with SP router.

You can have any kind of link from the SP, you can configure IPSec tunnel from end to end router.

You need to have the below pre-requisties:-

1.What kind of authentication you are going to configure ??

2.Tranformation Set -- Encryption alogorithm and Hashing method

3.Network which you are going to send and recieve the traffic via the IPSec tunnel.

For more information , have look into the below URL

Thanks

Hi,

Thanks for the response, i would like to know one more thing. In my IPSec tunnel, there will be NAT traffic one for particular destination IP , and rest of the traffic will go without NAT . My question , is it possible if yes then how ?
