I'll try to explain this as best I can, I'm not that familiar with WAN's and I am by no means a networking expert.
Our main internet connection is though a Comcast cable modem and behind that is our ASA5510. Our server takes care of DNS and DHCP using 192.168.100.0 and the subnet mask 255.255.255.0
We also have a T1 circuit through Verizon and a Cisco router. This is used to connect to a remote database server controlled by our parent organization. They have provided us with a group of static IP's: xxx.xxx.xxx.66 - 94. When we were just getting set up to use the database, I set up an old Linksys router and assigned it one of our static IP's for its untrusted interface and gave it 192.168.100.5 for its trusted interface. We connect to the database using a telnet client so I gave each workstation a static route so it would use the Linksys router as it's gateway when looking for the database server. This has worked out fine so far.
Now we need to set up a printer and the printer needs to have its own IP address which I assume will need come from our block of static IP's.
Right now, I have the trust interface from the Cisco t1 router plugged directly into the untrust interface of the Cisco router and the trust interface from the Linksys plugged into our main network switch.
What should I change so I can assign the printer one of our static IP's and have the remote database server print to it?
Would I just plug the trusted interface from the T1, the untrusted interface from the Linksys, and the network printer into another switch and a final cable from one of the trusted Linksys ports into our main switch?
I'm also including an image of the layout with the printer included.
