I am noobish so be kind.

Note: the server is runing SBS and has 2 NIC's

Questions I have:
1) Should I run the internet conection throug the server first even if I am not using SBS FW?
2) Shoud I rub dual FW... router and SBS?
3) Let SBS do DHCP and not router?
4) Let router do VPN and not SBS?
5) If I run it as shown can I do something with the 2nd NIC on server to help the netwrok?
6) Any other thoughts?

Thanks!

Sorry wanted to post under Questions. How can I move or delete it?
