Hi.
I'm currently running a Tor bridge on port 80 (for personal purposes, luckily no real needs). From what I can see in the obfs debug there's no connection other than mine, probably because the bridge is not (correctly) advertised on the Tor network (I guess).

I'm running it with a hack, because I couldn't find a better way to o so. Time ago I found an answer on SO [1] which explained how to run a bridge on port 80 via iptables rules, and that's what I do and works fine. But since the Bridge is online it's a shame others cannot benefit from it.

This is my configuration:
RelayBandwidthRate 900 KB
RelayBandwidthBurst 1 MB
ExitPolicy reject *:* # no exits allowed
DisableDebuggerAttachment 0
SocksPort 0
ORPort 2000
ExtORPort auto
BridgeRelay 1
ServerTransportListenAddr obfs3 0.0.0.0:8099
ServerTransportPlugin obfs3 proxy public_ip:80

When started Tor reports the ORPort as reachable, but that's not the obfuscated port. I guess many people can benefit from using a Bridge on port 80. 

So two questions:
1) is there a non hack-ish way to run a bridge on port 80?
2) how can I advertise the bridge on port 80?

Thanks
