Try setting rpcallowip to the exact IP address of the machine that is sending the requests.
Are the requests timing out or giving an explicit error?
It still times out. This is what my bitcoin.conf looks like.
I also tried to telnet *ipaddressofbitcoinserver* and it times out too.
Any other ideas? I'd love to get this done! Can I pay anyone some money to figure it out?
