My firewall is a Cisco ASA 5520 running 8.4(5).
I have to connect a site to site vpn tunnel from one private ip to 6 private subnets. I am working with another engineer on the other side.
private ip----outside static public ip<------site to site----->outsite static public ip----6 private vlans.
Each vlan has to be able to get to the private ip and vice versa. I am trying to figure out what would be the best configuration.
Any suggestions would be appreciated.
Thank you

I think there is no "best configuration" , just only one configuration that should work:
On your ASA configure the VPN with a crypto-ACL like the following:
object network PRIVATE-IP
host 10.10.10.10
object-group network REMOTE-VPN-NETWORKS
network-object 10.100.1.0 255.255.255.0
network-object 10.100.7.0 255.255.255.0
network-object 10.200.1.0 255.255.255.0
...
!
access-list VPN-XXX permit ip object PRIVAT-IP object-group REMOTE-VPN-NETWORK
!
crypto map VPN 10 match address VPN-XXX
On the other side, the crypto ACL has to be exactly mirrored. And you have to exempt the traffic from NAT.
