We have a single Blackberry router on the DMZ. A concern that I am faced with is if it fails over, I will need to bring another one line as you cannot cluster them according to Blackberry docs. So I was thinking:
1. Is anyone running Blackberry router, on the DMZ in a virtual environment?
2. Anyone in a DR situation brought or even does it normally, run the Blackberry router on the internal network, with port 3101 setup bi directionally?
Otherwise I suppose its a case of building a new piece of kit, setup same way as existing router, and have it turned off.
