Help with Gatewat-to-Gateway VPN & Multihomed Server

Using (2) Linksys RV042s in Gateway-to-Gateway VPN -Site A & Site B. Each site has a Static IP from ISP. I have established the VPN tunnel, however cannot connect to shared resource to/from either location and I think it is related to a networking/subnet issue.We only need to access a shared folder on our Server At Site A that has 10.10.10.150 as Internal NIC IP.

SITE A NETWORK: is a Win2K3 Domain running Active Directory with a server that has (2) Network adapters. The NICS are setup like this:

Internal NIC: IP=10.10.10.150 SN=255.255.255.0 GW=empty DNS1=10.10.10.150

External NIC: IP= 192.168.16.1 sn=255.255.255.0 GW=192.168.16.254 (this is the LAN IP of the RV042 Router at Site A) DNS=10.10.10.150

The workstations on this domain use static IPs on LAN: IP: 10.10.10.xxx DG: 10.10.10.150 DNS 10.10.10.150

RV042- SITE A -SETUP:

Local Group Setup: IP Only Static IP from ISP Local Security Group Type: Subnet IP: 10.10.10.0 SN: 255.255.255.0

Remote Group Setup: IP Only IP Addr: Static IP for remote site RS Group Type: Subnet IP: 192.168.1.0 SN: 255.255.255.0

IPSEC setup matches router at Site B as follows:

Preshared key/3DES/SHA1/14400 PFS checked; Phase 2 same as Phase 1.

SITE B NETWORK:

Windows XP PCs on peer-to-peer in a worksgroup. The RV042 here is running DHCP. The LAN IP of the Router is: 192.168.1.1. The workstations get

192.168.1.xxx addresses.

While at Site B, I can ping & remotely administer the router at Site A.

While at Site B, I cannot connect to \\\\10.10.10.150\\sharedfolder. I tried adding username from SiteB to the SiteA domain, and tried the "Connect as User" method.

Any ideas? Should we change the SiteB network to 10.10.10.xxx based or

192.168.16.xxx-based?
