Question on setting up a DVR to Cisco ASA 5505 for remote viewing. I have a 50 locations that I will need allow remote viewing for the DVRs. I have a question regarding how to set it up with the asa 5505 firewall. I have an idea but am unsure if its correct.

Im noob at networking so bare with me.

Each location is setup like this:

1 ISP modem in bridge mode that hooks up to the cisco firewall that does all the work.
We have one static IP from the ISP that ia used for the firewall.

So if i wanted to hook up the DVR to the cisco for remote access, would I have to get another static ip for the DVR, assign it to the DVR in the firewall configuration and forward the necessary ports?
