Yes, the ideal solution, and maybe the only one that'll work, is to
enable NAT-T on the concentrator.
The other thing I'd suggest trying is enabling advanced outbound NAT
and creating a NAT rule using the "disable port mapping" option so the
source ports don't get re-mapped. Some VPN concentrators don't work
unless you do this.
