During the course of my work, I have created an add-on to the Communications Server V1R7 NSCA GUI that allows the migration of definitions from Firewall Technologies to the new policy-based IP Security. I also helped author the accompanying guide that explains its usage and the limitations/capabilities of the tool.

Have your computer tell you when your home IP address changes!
I thought I would post a link to something I created in the past. I wrote a daemon with an extendable API that allows you to receive updates and/or update something else such as DNS or a webpage when your home computers public IP (or WAN) address is changed. This can happen for any number of reasons such as an ISP change of infrastructure, regular DHCP release and renew, as well as just because ISPs sell you dynamic addresses and therefore it may change so you don’t run publicly accessible services from home. Whatever the reason, if you’d like to still be able to access your assets at home when your public IP address is volatile, here is a tool you can use:

In addition, I tend to try and use whatismyip.com in conjunction with this tool (the available, already written plugins need a public web-site that reports the IP address it sees); however, it tends to limit how many times a day you can check. I have created a simple page that lets you get that information:
Enjoy!
