I have a similar router. Here's a workaround -- as you know. For others this may be helpful.
You can add the LAN IP addresses to your hosts file. I am using Win XP Pro and the hosts file can be found here: C:\WINDOWS\SYSTEM32\DRIVERS\etc
Open with Notepad. Note: the hosts file does not have a suffix so don't save as txt file (rename if necessary). The hosts file looks like this:
# Copyright (c) 1993-1999 Microsoft Corp.
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
# For example:
# 18.104.22.168 rhino.acme.com # source server
# 22.214.171.124 x.acme.com # x client host
Just add your LAN IP numbers and computer names after 127.0.0.1 localhost, like this:
192.168.0.100 whatever name 1
192.168.0.101 whatever name 2
192.168.0.102 whatever name 3
192.168.0.103 whatever name 4
Since this is on local you will have to do this for all computer on the LAN, of course. It's a good workaround. More here:
