IPsec protocol: The desired IPsec protocol (AH or ESP)
Encryption algorithm: The desired IKE encryption method (we recommend AES256)
Authentication algorithm: The desired IKE authentication method (we prefer SHA1
over MD5)
SA life time: The lifetime of Security Associations
Networks
When creating Security Associations, IPsec will keep track of routed networks within
the tunnel. Packets will be only transmitted when a valid SA with matching source and
destination network is present. Therefore, you may need to specify the networks right
and left of the endpoints by applying the following settings:
Local network address: The address of your local area network
Local network mask: The netmask of your local area network
Peer network address: The address of the remote network behind the peer
Peer network mask: The netmask of the remote network behind the peer
NAT address: Optionally, you can apply NAT (masquerading) for packets coming from
a different local network. The NAT address must reside in the network previously
specified as local network.
