cat /tmp/resolv.conf.auto
The output of this command gives two nameservers, they are my ISP's DNS servers and not OpenDNS as I have configured :(

You could try and do one other test.
Is it possible your ISP is forcing you to use their DNS?

If you hookup 1 PC directly to the modem and under
the configuration for your network card

Find the setting where you can choose the radio button for

Use the following DNS servers

And enter in the IP addresses of OpenDNS

Then try to disable and re-enable the network device
After that try doing an

IPConfig /ALL

from a command line window

IF the openDNS servers still do not show up there,
then your ISP might be forcing you to use their DNS servers?

Trying to delve a little deeper but not getting very far.
All my experience with BusyBox (not very much) up till now has been with setups where all the commands have been compiled into BusyBox.
I tried:

Code: Select all

ln -s /bin/busybox ls
./ls
the system returns with:

Code: Select all

ls
I suspect this means ls has not been compiled into BusyBox.
Am I right?

PS. Forget my question. I'm making slow progress now. :oops:

Eric: In response to the following:

Code: Select all

cat /tmp/resolv.conf.auto
I get:

Code: Select all

nameserver 192.231.203.132
nameserver 192.231.203.3
These are the Primary and Secondary DNS Servers of my ISP provider.

Re: Dynamic DNS Improvements

Post by uncle john »

Apart from my mistaken thinking that checking WAN IP was the default setup for DDNS, the other reason I pursued the PPPoE connection setup was that I thought it would make things easier when connecting Gargoyle to a modem/router that used the same address space as Gargoyle (ie. just set it to bridge mode).
One such modem/router is the Billion Bipac 5100.
In my earlier posting where I said I had achieved success with a DHCP connection I used a Cisco router which uses a different address space than Gargoyle.
I have now achieved success using a Billion Bipac 5100 by setting it's DHCP server to "Relay" and the Gargoyle WAN connection to "Static IP (Wired)".
Following are details of Gargoyle inner settings with this setup for those that understand all this stuff:

Ok.. I think I may have identified the problem with open DNS for people using PPPoE. Below is a link to a (broadcom-2.4) test build with an experimental fix. If someone who has a PPPoE connection (BikeMike? uncle john?) could test this, it would be much appreciated!

I can confirm that the 1.0.10 test version now works correctly for me on PPPoE using alternate DNS servers. The force option also works as expected. QOS graphs are back too. :)

As a feature suggestion, it would be good if I could use the force DNS option but have exceptions for 1 or 2 client PCs. (ie. OpenDNS forced for kids site blocking but adult PCs use an alternate DNS configured on the PC)

For now I have added OpenDNS servers but not using the force DNS option, so they are only used by default. This is probably good enough for non-Tech savvy kids!

Eric: My wife thinks she is a computer widow at the moment so I won't be testing this for a while. From what BikeMike says I'm pretty confident that it works OK. Thanks so much for sorting this out. :D

Alternatively use multiple PPPoE connections. See my comment at http://www.gargoyle-router.com/phpbb/vi ... t=10#p1633
