So far I have a good VPN tunnel between to sonicwall appliances.

My configurations:
Main office –
Sonicwall WAN IP
Sonicwall LAN IP is
LAN IP range is 192 168.100.1- 199  subnet
(Removed the range from DHCP for remote VPN users)
Network has a local DHCP server, DNS server for Active Directory as well as WINS server
VPN tunnel ends at the LAN

Remote Office -
Sonicwall WAN IP
Sonciwall LAN IP is
LAN IP range is 205 Subnet
Sonicwall is acting as this sites DHCP server and also assigns the sites WAN DNS address as well as the Main offices LAN DNS address.
VPN tunnel ends at the LAN

Although I have a good VPN tunnel (green light between appliances) I’m not able to ping or otherwise communicate between computer systems on each end of the VPN link. I’m guessing that I need a different subnet per LAN but before trying all kinds of crazy things I thought I should ask .  So if you can lend a hand in pointing out my screw up I would greatly appreciate it.
