For the outgoing data filters:
- Deny "bounceback" packets
- Allow packets that originate from us
Filter Type= TCP/IP Filter Rule
Active= Yes
Destination: IP Addr= a.b.c.d
Destination: IP Mask= w.x.y.z
Action Matched= Drop
Action Not Matched= Forward
where a.b.c.d is an IP address on your local network and w.x.y.z
is your netmask

I want to assign an IP address to my workstation
dynamically...how?
The Router can assign IP addresses during the IPCP negotiation,
but that only applies to the device that's calling in, either a
remote router or a remote workstation with a TA. The Router
cannot assign IP addresses to any workstations behind the router,
because nothing on that workstation performing the IPCP
negotiation.
In the case of a workstation calling in using an ISDN TA, the
Router is able to assign the IP address because it is the
workstation that is doing the actual PPP/IPCP negotiation.

How can I prevent incoming telnet sessions to my Router?
The Router has implemented a telnet password, which must be
entered before a telnet session is established. This password is
the same as the system password configured in menu 23. In
addition, the Router will only allow one administrator to
configure the device at a time. Any attempted telnet session
will be rejected if an administrator is already logged into the
SMT.
If you want to block all incoming telnet sessions from being
established, you can define an IP filter and plug it into the
incoming data filters for appropriate remote connection:
Filter Type= TCP/IP Filter Rule
Active= Yes
IP Protocol= 6
Destination: IP Addr= w.x.y.z
Destination: IP Mask= 255.255.255.255
Destination: Port #= 23
Destination: Port # Comp= Equal
Action Matched= Drop
Action Not Matched= Forward
where w.x.y.z is the IP address of your Router.
