  > Enable NAT Traversal (NAT-T)
Set this option to enable the use of NAT-T (i.e. the encapsulation of ESP in UDP packets) if needed, which can help with clients that are behind restrictive firewalls.
DPD interval seconds
Enter a value here to enable Dead Peer Detection (e.g. 60 seconds).
Phase 1 proposal (Authentication)
Negotiation mode
Aggressive is faster, but less secure.
My identifier
Encryption algorithm
Must match the setting chosen on the remote side.
Hash algorithm
Must match the setting chosen on the remote side.
DH key group
Must match the setting chosen on the remote side.
Lifetime seconds
Authentication method
Must match the setting chosen on the remote side.
Certificate
Paste a certificate in X.509 PEM format here.
Key
Paste an RSA private key in PEM format here.
Phase 2 proposal (SA/Key Exchange)
Protocol
ESP is encryption, AH is authentication only

Hint: use 3DES for best compatibility or if you have a hardware crypto accelerator card. Blowfish is usually the fastest in software encryption.
