                    LOCALIP [--ipsec]

Requirements

Written in Python 3.6 but could probably be adapted for earlier versions.

Install

Basic virtualenv install

virtualenv -p python3 aws-vyos-config
cd aws-vyos-config/
. bin/activate
pip install -r requirements.txt

Example

./getconfig.py -p <my aws profile> --id vpn-123abc456> --vti vti0 vti1 --localip 10.255.0.4

Note the two vti devices are required. One for each tunnel.

Testing

Will accept PRs!

Development

If you'd like to contribute, the following may help.

aws --profile <your ~/.aws/credentials profile> ec2 describe-vpn-connections

the important part in here is CustomerGatewayConfiguration which is the configuration in XML format
