Dual Boxing with VMware (UO)

Hi!, i'm kinda a newbie to dualboxing, so i need a few hints!
here's my issue:
i play Ultima Online on a private shard, what i'd like to do is basically to open another game on my Virtual Machine(installed using VMWare, WinXP Home SP3) wich i already did and played for a bit with 2 windows, one on my host pc, one on my guest (i need this configuration cause the game will take controll of the mouse on my Virtual Machine...so by doing this i can still use my pc and actually play while the VM "plays by itself")

i've already managed to do all of this, the game is already installed on my VM, if i run it, it works, and stuff...
HERE COMES THE ISSUE:
a few days ago a game master found me and, probably by matching my IP adresses found out that i was playing with 2 accounts at the same time.
nothing drastic, he just warned me that was no more allowed to do that... i would risk 14days of jail xD fffffffuuuuuuu

NOW: i'm not giving this up still...
is there any way to actually HIDE or MASK the IP of my Virtual Machine? so that they can't match it with my original pc's IP? i need my VM to look like another computer NOT COMBINED with my host pc in anyway! possibly from another place
and i need this to be solid *_* a don't wanna get banned xD

is it possible?
thank you so much for your help and experience
and sorry for my english, it is not my mother lenguage

We're not going to help you bypass the rules of the game in order for you to multibox it -- That's not what this site is about.
