Using sr102 in dmz mode

I've read on the net the Sr102 doesn't support VPN Pass thru. However it has come to my attention I can work round this using a DMZ in combination with my WNR3500L. It supports vpn passthru. I have tested this using windows itself to create a vpn.

SkyHUB -------> WNR3500L Wan port ----->rest of network

The firewall on the WNR3500L is enabled with UPNP disabled.
The skyHUB serves only as a gateway to the internet , nothing is connected to it besides the Wnr3500L.

Is there anything seriously wrong with this?

It means double NAT, which can sometimes cause issues with some apps, but if it works for you VPN needs then give it a go.

Also nothing to stop you still using the NAT on the SR102 for other machines still if the double NAT does cause issues.
