problems with bridge-relay

[sigi]

Hi, 

I switched from a middle-man-node to a bridge-relay on my vserver 
today...

I installed Tor 0.2.0.23-rc on my Debian-system and set the following 
options in my torrc-file:

SocksPort 0
ORPort 9001
BridgeRelay 1
RelayBandwidthRate 50KBytes
ExitPolicy reject *:*
AuthoritativeDirectory 1
BridgeAuthoritativeDir 1

But with this setting, I get the warning-messages like: 
Apr 08 19:22:41.312 [warn] Your server (62.75.149.148:9030) has not 
managed to confirm that its DirPort is reachable. Please check your 
firewalls, ports, address, /etc/hosts file, etc.

Nmap shows, that the ports are open:
PORT     STATE SERVICE VERSION
9001/tcp open  unknown
9030/tcp open  unknown

Has anyone an idea, what's wrong with all this?

Thanks a lot,
sigi
