My proxy (160.13.1.21) is behind a firewall

When I connect a proxy client to the web, I receive the following
error message in cache.log :

2005/11/30 11:42:43| Detected DEAD Parent: 160.13.1.21/8081/0
2005/11/30 11:42:43| TCP connection to 160.13.1.21/8081 failed

2005/11/30 11:42:44| never_direct = 1
2005/11/30 11:42:44| timedout = 0

And there is another warning in access.log :

1133343958.794 2 160.13.54.27 TCP_DENIED/407 1639 GET

Any idea?
Thanks in advance!
