http proxy blocks Linux update (apt-get update)
now that the Watchguard T35-W is online in my network for a few days, several Linux servers are having problems retrieving their updates.
The affected servers get their IP via Firebox dhcp server, where gateway, routing and basic internet access works. I use my own bind DNS server as DNS forwarder which is also listed in the DHCP options for the client.
I suspect the http proxy and after internet research I have the IP address and the sources which are listed in /etc/apt/sources.list and the web blocker, apt blocker I have deactivated test wise; unfortunately without success.
I tested the DNS name resolution, it can't be because of that.
I am currently working with the Firebox Web interface and as log the Dimension Appliance.
I can remember that in the past you could deactivate the http proxy completely by logging in, however.
Therefore my questions: The log concerning http Proxy in Dimension is not really informative. Where can I inspect the http proxy log?
Is there a way to disable the http and https proxy for an IP or IP range?
Thank you for your feedback.
