Yes, IPSEC borks when one of the endpoints goes through NAT. I agree
with Les, you seem to need NAT-T, and both the server and client need
to support this, so check your VPN documentation.

I don't think that there's any need in configuring anything specific
on the NAT gateway, as long as the firewall allows UDP port 4500
(NAT-T) to flow.
