I am looking to setup a VPN solution with two cisco 871 routers.
Remote net 10.10.1.0
Cisco 871  Int vlan1 (10.0.1.1 255.255.255.0)
                 Int fa 4 (9.10.11.12 255.255.255.252)


DMZ net 10.10.10.0
There is a csu/dsu  11.12.13.14
that provides public ethernet address to 871 Int fa 4 (11.12.13.15 255.255.255.252)
    Int vlan1 (10.10.10.1 255.255.255.0)
The 10.10.10.0 network is on the public side of the SBS ISA server (10.10.10.2 255.255.255.0)

Local net 10.0.0.0
sbs ISA server is 10.0.0.1

need to have 10.0.0.0 network and 10.0.1.0 network on private lan
need to have 10.0.1.0 go throgh vpn to get to 10.0.0.0 network, go out to 9.10.11.12 for internet traffic.
10.0.0.0 network will go throgh sbs isa server for network traffic.

can the 10.0.1.0 go through isa or do I need to make another vlan on another port on the 871 and bypass the isa server?
