HVN Gateway - How do I create S2S VPN to customers who only have IKEv1 available?

HVN Gateway - How do I create S2S VPN to customers who only have IKEv1 available?

I would say 90% of the sites I need to connect to are only at IKEv1.  I only see IKEv2 available?  Is there a work around for this deficiency?

Thanks,

Jason
