cisco vpn interfering with screen sharing
i get this error message when i try to screen share from my macbook pro to my g5 desktop whenever i have my vpn client connected to my office network. i'm using cisco vpn client version 4.9.01(0100). screen sharing connects fine as soon as i disconnect the client connection. my macbook connects via the wireless network connected to the g5, a linksys WRT54GL.
i was able to screen share without difficulty until several weeks ago and am just recently realizing the screen sharing issue is reliably related to the vpn being connected.
knowing very little about networking, are there some port changes or something i need to make to allow both connections at the same time (realize i say "port changes" without really knowing what the heck i'm talking about or where those changes would be made).
thanks for any help,
