Modify WEST's connection to EAST

This task modifies the connection from WEST to EAST to use RSA digital signatures for authentication. In this example:

  • The authentication mode is changed from pre-shared secret to RSA digital signatures.
  • EAST's public key is specified as the remote key, under the identifier configured in Record EAST's public key on WEST.

To modify the site-to-site connection to use RSA configuration, perform the following steps:

Table 1. Configure WEST for RSA authentication
Step Command

Remove the pre-shared key.

vyatta@WEST# delete security vpn ipsec site-to-site peer 192.0.2.33 authentication pre-shared-secret

Change the authentication mode.

vyatta@WEST# set security vpn ipsec site-to-site peer 192.0.2.33 authentication mode rsa

Provide the identifier for EAST's digital signature.

vyatta@WEST# set security vpn ipsec site-to-site peer 192.0.2.33 authentication rsa-key-name EAST-key

Commit the configuration.

vyatta@WEST# commit
