i'm trying to connect my phone to my mac via VNC. when i have no internet connection, i just use an ad-hoc network and it connects fine. when i'm on my own network, i just connect to my mac's IP address and it works fine. but when i use a USB EVDO card to connect, i can't get it to connect. it tells me the ip is something like 175-255.myvzw.com now, the EVDO card's internet connection is separate from the Wifi connection. so i set up an ad-hoc network to run at the same time as the EVDO card. the iphone connects to the ad-hoc connection, but can't connect to the computer. the mac is telling me i have to connect to the verizon IP, not the ad-hoc ip. SO MY QUESTION is: what can i do to keep the EVDO connection separate from the ad-hoc wifi network for the purposes of VNC?
