Cannot use a PPPoE DSL connection

RouterOS Beginner Basics
1

I am trying to connect a mikrotik router to TekSavvy DSL.
I followed the instructions at http://wiki.mikrotik.com/wiki/Manual:Initial_Configuration including the troubleshooting section.
I have no problems using the internet with the modem connected directly to my computer.

The router gets a WAN IP, and I can ping google.com through the router, but no computer on the network can access the internet (ping 8.8.8.8 and ping google.com fails on computers on the network but works fine through the router command line).

I’m not really sure where to look or what to search for or what to do. Any suggestions would be appreciated.

Thanks.

Some information on what you did to configure your router would be useful.

I’m very new to this mikrotik thing - what information would you like me to provide?

I followed the suggested setup here exactly:
http://wiki.mikrotik.com/wiki/Manual:Initial_Configuration
on a fresh-out-of-the-box mikrotik router. I skipped sections 3.3.1 and 3.3.2 as it does not apply to my current internet service. When setting up DNS (section 3.3.5), I added the OpenDNS servers (208.67.222.222, 208.67.220.220).
I then added a PPPoE client interface on ether1, entered the information from my ISP, and the router connected to the internet. I was able to ping 8.8.8.8 and google.com through the router.

However, no computer on the network is able to access the internet, or ping google.

When I connect the modem directly to my computer, I have no problems accessing the internet.

Did you configure the firewall?

In what way? I configured NAT as suggested. Otherwise its default settings.

Did you set the firewall to masquerade outbound traffic?

It would be easiest to comment on the full config (output from /export compact).
