Remote 812 ADSL Router

v 1.1.7 Release

October2000

New Features:

*Added PPPoE Client on a Remote Site VC profile (WAN inter-

face).

*Added DHCP Client on a Remote Site VC profile.

*Added IP Management address on a VC Remote Site profile.

*Implemented an Access List to restrict access to the 812's Man-

agement Services (HTML, telnet, tftp, snmp).

*Increased number of filters conditions from 40 to 120.

*Modified the NAT component to translate protocols other than

TCP, UDP, ICMP, and GRE.

*Added a Watchdog timer.

*Added canned filters to block file and printer sharing ports (TCP

139 & 143 and UDP 137 & 138).

*Added DIP switch setting to enable default ADSL Open Mode.

Set DIP Switch #1 “on” for ANSI or “off” for MultiMode.

Bugs Fixed:

*Corrected mask and offset of the generic filter to allow specific

bits. One can now define a filter rule to reject incoming TCP

connections.

*Corrected error in the console password logic which resulted in

the unit to "hang". The CLI command to enable this feature

was modified to ensure the user entered in a known password.

See "CLI notes" below.
