What kind of vpn are you connecting to? If it's cisco you're in luck -- there is a very good cisco client called "vpnc". You may also need the kernel module for the "tun" virtual interface, if it's not included in the stock VL kernel. I haven't tried it on VL yet but I will soon. Works great on the "brown" distro.
Were you able to install the cisco vpn client successfully? I just recently downloaded cisco vpn client from my college campus website, but was unable to install it.
