3.5 ROM: Internet Sharing/VPN/Remote Deskop?

[kconcilio]

I have Kirvin_CS_35_104_Sprint ROM installed and I love it. The only issue I am facing is that I am not able to use Remote Desktop on map laptop while connected via Internet Sharing and my company's Cisco VPN Client. I do not have any issues using Remote Desktop while connecting via Cable Internet and the VPN. I was able to use the phone as modem feature of the 2.09 Sprint stock Rom without any issues. Is there a configuration setting on Internet Sharing that would allow me to get this to work or is this just a limitation of this type of connection?

There apparently is no solution for 3.5, but I reinstalled helmi_c's WM6 ROM and now I have the modem back and it works like a champ! Hugh thanks goes out to thisguyinoc for his post.
