IP Protocol Number
The type of protocol to tunnel. Drop down menu includes GRE, TCP, UDP, ICMP and specific protocol
(number) or any protocol to allow all protocols to be tunneled. DMVPN typically uses GRE for IPSec+GRE
tunneling (so other traffic like pings are unencrypted).
ESP Proposal Encryption Algorithm
Encryption algorithm for IKE SA exchange for this tunnel.
ESP Proposal Authentication Algorithm
Authentication algorithm for IKE SA exchange for this tunnel/transport. Only applicable for CBC and CTR
based encryption algorithms.
ESP Proposal DhGroup
Diffie-Hellman algorithm for IKE SA exchange for this tunnel, or none if not required.
