[tor-talk] Why isn't my proxy working?

[Clare ♬]

I'm using an isolating proxy that I've set up on a separate machine running Tor on OpenWRT. I can connect to it, and ping my computer from the Tor machine, but when I try to browse the internet, I'm told that my proxy is refusing connections. I'm thinking that there must be a problem with my firewall rules. 
Here's a link to a question I posted that includes the rules (I won't post them here directly, as I've had issues with formatting in the past): http://tor.stackexchange.com/questions/3551/why-isnt-my-tor-proxy-working
Any help is appreciated!
