Connect two Networks together

I am working with two seperate networks. Both of the networks are on the seperate subnet. Here is a brief diagram.

Network 1 - subnet 192.168.168.0 (running Active Directory, Exchange,DHCP,DNS,WIns servers)
Network 2 - subnet 192.168.1.0 (running Active Directory, Exchange,DHCP,DNS,WIns servers)

Two networks are seperated with a Sonic 3600 Standard firewall and are connected to their seperate ISP's.
Network 1 - is connected to the T1 line
Network 2 - is connected to the ADSL
I need to join those two networks together so that I can share some files etc... im not sure what is the best approach for this.

The sonic firewalls have 3 interface ports each. 1-LAN 2-WAN 3-DMZ
Can I perhaps link the two sonic walls together through the DMZ interfaces?

So I take it you want to do something like this

T-1 ADSL
| |
Sonic1 (DMZ)<--->(DMZ)Sonic2
| |
192.168.168.0/24 192.168.1.0/24

I so, then it shouldn't be a problem. Just link the DMZ interfaces (most likely with a crossover cable) and create a small network like 192.168.100.0/30 and assign 192.168.100.1 to Sonic1 and 192.168.100.2 to Sonic2. Then make sure to have routes in each Sonic so that it knows to find the other network thru its DMZ interface. However, I'm not familiar with Sonicwall's so I'm not positive if its totally that simple when doing the config or not, but the logic should work provided I understood you right

Hi Cyclops3590, yes it is quite simple in sonic firewall to configure the interfaces etc... do you think that i will need to set up rules, like for example to allow traffic from DMZ > LAN and vice versa?
