I don't have anything constuctive to suggest for your problem, but I thought I'd let you know you don't need to worry about publicizing your IP address.. At least in this case.
192.168.x.x is what's called an RFC 1918 address range. It is not internet routable, and often used in private networks. You'll typically go through a device that uses NAT if you can access the internet from that address, but noone can get to you via that address.
EDIT: In your case, you are using ICS, which implements NAT.
Just like 10.x.x.x, or 127.x.x.x
Just something for future reference anyways
