Sophos Not Updating After Upgrading to Astaro to 7.x
March 13, 2009
Problem: After upgrading from Astaro
Background: Because Sophos is configured to update using the external internet address(update.domain.com), a NAT rule was created to redirect the public IP request to the internal address of the update server. Sophos would make the request to the update server but when the update server tried to respond, Astaro would drop the packets, tens of thousands of requests would be dropped. Working with Astaro support, we determined that the updates were failing because of the transparent proxy.
Solution: Added the update internet address to the “Skip transparent mode hosts/nets” list. You can find this under Web Security – HTTP – Advanced. Once added updates were successful.
