You sir are a gentlemen and a scholar. I managed to use your instructions and I can now mine any pool over any port I feel like behind a rather restrictive firewall.
Glad that I could help. Some people might use this to mine behind firewalls or, at their own peril, on business machines. As Luke stated, port 80 works as well. I still have the intermittent problems if I try port 80 so I'm sticking to my solution for the time being.
I really want to see this pool succeed. I somewhat dislike proportional pools because they are quite easy for pool-hoppers to take advantage of. I showed a few friends 'the light' this evening and they are moving their 2GH/s rigs over from btcguild for a few days to see how it pans out. Hopefully they will stick around. The more power, the better!
