7.50X HTTP proxy blocking traffic

tdutrieux
Hello,

I just want to try using the Web proxy from an external (public address). Here's the setup :

Client (public IP) ---TCP 22---> External Astaro IP ---> NAT to Internal Astaro IP (TCP 8080).

Proxy configured on client is external astaro IP port 22.

I get the following message on the client :

"Astaro Security Gateway Version 7
An error occurred while handling your request
While trying to retrieve the URL: http://www.google.be/
Error message: Received invalid request from client
Your cache administrator is:
admin@localhost

Powered by Astaro"

And in the Astaro web proxy log :
2009:10:29-08:26:30 astaro httpproxy[4217]: id="0002" severity="info" sys="SecureWeb" sub="http" name="web request blocked" action="block" method="GET" srcip="PUBLIC IP" user="" statuscode="400" cached="0" profile=" ()" filteraction=" ()" size="2185" time="0 ms" request="0x808a098" url="www.google.be/" exceptions="" error=""

Any idea what happens ?

Kind regards,
Thibault

    SNAT might work in transparent mode because the Proxy captures port 80 traffic.  Like I said, it's an experiment.  I wouldn't recommend anything other than 'Remote Access' because I don't like to open inbound ports.

    Cheers - Bob
