I'm trying to setup a VPN between RHEL7 and Google Cloud VPN. I keep
getting this cryptic error:
"google-tunnel" #6: ignored CCM/GCM ESP proposal 1: integrity transform
must be IKEv2_AUTH_NONE or absent
ikev2_parent_inI2outR2_tail returned STF_FAIL with v2N_NO_PROPOSAL_CHOSEN"
This is with a barebones configuration like:
conn google-tunnel
authby=secret
auto=start
type=tunnel
left=x.x.x.x
leftid=x.x.x.x
leftsourceip=x.x.x.x
leftsubnet=x.x.x.x/24
right=y.y.y.y
rightsubnet=y.y.y.y/16
rightsourceip=y.y.y.y
As well as if I try to force some algorithm like:
ike=aes-sha1
ikev2=insist
phase2=esp
phase2alg=aes_gcm_c-128-null
Anybody have any ideas?
