2 X Complete networks conncted with ethernet on firewall?

Question

I have 2 separate networks operating with their own firewalls, internet connection and servers each in its own subnet on the inside.
I have been tasked to inter connect these networks to communicate with each other by inter connecting the firewalls (1 X ASA5510 and 1 X Lucent) with an Ethernet connection / network cable on each firewall.
What is considered the best way, DMZ interface on both, interconnecting?
Any Ideas?

Hello;
On the router, you can put a host route for the IP address 63.x.x.x pointing to the 212 address of the ASA? I believe that is what you are missing.
Configuration example.
ASA nat (inside,outside) source static 10.2.4.2 63.1.1.2 
On the router:
ip route 63.1.1.2 255.255.255.255 212.1.1.2 (assuming 1.2 is the firewall)
That would do the trick.
