I need to add a 2nd IP, set up the SSH and transfer the configuration from another switch.
To add the 2nd IP, firstly you need to add that on the AWS instance (follow the below link):
https://docs.telcobridges.com/tbwiki/FreeSBC:Cloud:AWS_Additional_Interface_A
then you will see it on the Web portal → IP interfaces.
Follow the below link to add virtual port, and IP interface:

You will need to add a new transport Server if you want to configure NAP on this new 2nd IP interface:

For SSH access, You can upload the new key in putty, then you shall be able to access both AWS:

Normally it is very straightforward to import configuration between SBCs, however for AWS, It is not recommended, which could cause some issues and you might lose access since too many changes including the IPs. Another approach would be to use tbconfig command (it might work on AWS):
