In case you want to privilege access via a particular PPP entry for
specific PCs, proceed as follows:
Step Action
1 Configure the PCs, to which you want to privilege outbound access
via this PPP entry, in a particular subnet of your local (W)LAN.
Note: Do not forget to make the AST570 also a member of this
workgroup.
2 Configure the 'Connection Sharing' box of the particular PPP entry
for 'My net only'.
3 It is sufficient now to open the PPP session of this PPP entry from one
PC of this subnet.
As a result, only the members of that particular subnet can share
this PPP entry.
The 'Destination networks' field allows you to configure which
destination can be reached over the particular PPP entry.
Four options are available:
All networks
"
The AST570 can potentially route frames to all destinations
over this PPP entry. The PPP entry acts as if it was a default
gateway.
Remote net only
"
A PPP entry configured for 'Remote net only' only forwards
frames that is destined to this specific network. All other
frames are blocked.
Remote host only
"
Only those frames with a destination IP address which
matches exactly with this entry in the AST570 routing table
are forwarded over this PPP entry. In fact, only communication
with the single remote host is possible.
Specific network defined below
"
If all previous cases do not fulfill your requirements, 'Specific
network' might help you out: you can specify which
destination(s) are reachable over this PPP entry. Only if the
destination IP address of a packet matches with this entry the
packet is forwarded over this PPP entry.
