Configuring Dial-In Users 7-9
Configuring Network Users
The PortMaster supports Stac LZS data compression only for PPP connections with
bidirectional compression. Stac LZS data compression cannot be used for SLIP
connections.
To set header compression for a network user, use the following command:
Command> set user Username compression on|off
Table 7-3 describes the results of using each keyword.
To find out what type of compression was negotiated for the user, enter the following
command:
Command> show S0
Setting Filters
Input and output packet filters can be applied to each network user. If an input filter is
applied to a user, when the user dials in and establishes a connection, all packets
received from the user are evaluated against the rule set for the applied filter. Only
packets allowed by the filter can pass through the PortMaster. If an output filter is
applied to a user, packets going to the user are evaluated against the rule set for the
applied filter. Only packets allowed by the filter are sent out of the PortMaster to the
user. If either filter is changed while a user is logged on, the change will not take effect
until the user disconnects and logs in again.
Note – You must define a filter in the filter table before you can apply it. For more
information about filters, see Chapter 9, “Configuring Filters.”
To apply an input filter for a network user, use the following command:
Command> set user Username ifilter [Filtername]
Table 7-3 Keywords for Configuring Compression
on Enables compression. The PortMaster tries to negotiate both
Van Jacobson and Stac LZS compression on PortMaster 3 and
on leased lines on Office Router products, or Van Jacobson
compression only on other PortMaster products. This is the
default.
off Disables compression.
