Hie, I would've tried something different if I had the possibility to choose. This is a solution chosen by the company I work for. Are you sure about that IPSec can't be NATed? NAT-T is kind of meant to handle just that. Also, my colleagues have no trouble through e.g. D-Link routers. The ISAKMP part NATs just fine...
