This option enables IPsec AH for a tunnel with a specified authentication algorithm. The auth_algs option has the following format:
auth_algs authentication-algorithm |
For the algorithm, you can specify either a number or an algorithm name, including the parameter any, to express no specific algorithm preference. To disable tunnel security, specify the following option:
auth_algs none |
For a list of available authentication algorithms, run the ipsecalgs command.
The auth_algs option cannot work with NAT-Traversal. For more information, see IPsec and NAT Traversal.
