Double NAT creates too much overhead and it doesn't double the protection
level.

If you have VPN connections using PPTP, you will need to allow TCP port 1723
and Protocol 47 (GRE) to pass through. If you are using L2TP/IPSec, you will
need UDP port 500 and Protocol 50 (ESP) to pass through. If you are using
AH/ESP in your IPSec policies, you will also need Protocol 51 (AH) to pass.

Both router and firewall might have the settings for IPSec pass-through and
PPTP pass-through. RTFM as always.

Ask about SBS setup as VPN server in microsoft.public.windows.server.sbs NG.
