We have hosted an Aruba Virtual Gateway on AWS. All the configurations are done as per the documentation of Aruba VPNC. Through AWS security policies, UDP 4500 is open on AWS side. We want to establish a site-to-site VPN to Cisco ASA at remote location. What are the steps involved in bringing up the tunnel. Tried couple of different settings and never could get the IKEv2 or IPSec SA established.
Should NAT-T should be enabled on Aruba Virtual Gateway side or both sides?
