Newbie config help

Hi a Newbie to deep unix here

Need to connect to a NetScreen VPN from a NAT’s 10.2 box (NAT using Apple Base Station – Snow)

I have my IP
The ABS IP
The Cable modem IP
The Netscreen IP
The Network IP

and an account un and pw

Tried VaporSec 0.8 and can’t attach

Is it a) possible or b) is there a magic ingredient I don’t know about?

regards

Richard
