hi all

I'm desigining control program for CyberCafe.
( there is 1 PC connect to the internet and 5 other PC connect to first PC via LAN, sharing internet, using
Windows98SE's Internet Connection Sharing )

a. customer must log-in first to gain access to internet
b. ( VB6 must do something to enable this PC share
internet )
c. after login, the timer is counting
d. after customer logout, the printer print the bill, and
e. ( VB6 disable Internet access via LAN )

can anyone help me about point (b) and (e) please ?
maybe i must configure with functions in ICSAPI32.dll ?
or maybe i must change GateWay setting in system registry ?

Thx
