[strongSwan] Strongswan connection to Sonicwall Enhanced OS 4.x using IKEv2

[Jack Omalley]

Has anyone gotten Strongswan to connect (using IKEv2) to a Sonicwall running Enhanced OS 4.x? I have spent several hours on this, and have gotten nowhere.

I've got a stripped down config in a test environment, and when I try to make a connection, I get


root at mercury:/home/user1# ipsec up home
initiating IKE_SA home[1] to xx.xx.xx.xxx
generating IKE_SA_INIT request 0 [ SA KE No N(NATD_S_IP) N(NATD_D_IP) ]
