Glad you got your device working.  You might try this if you can't
leave "well enough" alone.

The following is offered as an FYI and a heads up to someone that
might be able to help me with iptables at one of the next meetings.

There is an open source project for these routers.  I've just updated
the firmware in mine to the one of the latest releases of    openWRT.
Once installed  the router returns a nice little 'logon:' cursor.
Telnet in, type 'root' with no password and you are good to go.
(Note: After the first login telnet is shut down and ssh is turned
on.)

I have the WRT54GL, popular belief is that the L stands for linux
because this model had considerably more memory than the 54G's.
Jim, yours will likely will run openWRT.
see:

the following are a few commands and their responce.

root at 10.0.0.50's password:
BusyBox v1.11.2 (2009-01-06 07:18:07 CET) built-in shell (ash) Enter
'help' for a list of built-in commands.

I hope to get to the next LUG meeting and pick the brain of someone
that knows about iptables.  The following is the contents of the
firewall that is included with the installed firmware.  I have
questions about what is and isn't being let thru.  These question can
wait till I get to a meeting. Anyway here is the file.


root at OpenWrt:/etc# cat /etc/config/firewall config defaults
	option syn_flood	1
	option input		ACCEPT
	option output		ACCEPT
#	option forward		REJECT
	option forward		ACCEPT

config zone
	option name		lan
	option input	ACCEPT
	option output	ACCEPT
#	option forward	REJECT
	option forward	ACCEPT
	
config zone
	option name		wan
	option input	REJECT

	option forward	REJECT
	option masq		1

config forwarding
	option src      lan
	option dest     wan

## Enable this option if you encounter any MTU problems ## e.g. some
websites work, others do not, submitting ## forms causes problems, ...
#	option mtu_fix	1

It is a slick little device, it also has a very nice web interface.
People have even attached SD memory cards to the motherboards and use
them as various types of little servers.
