We recently upgraded to 5.0 and one of the first things I wanted to try out was the dynamic block lists. I set up 4 block lists (dshield, zeus tracker, palevo tracker, spyeye tracker) and tested to make sure the URLs were accessible. I rec'd the message that they were accessible/readable, so I set them to pull data daily at 7:00am, 7:01am, 7:02am, and 7:03am. It turns out the files weren't in the correct format so we got the message that no valid IPs were found (or something like that). At 7:00:59am the firewall started to go a bit haywire. DHCP would not traverse the firewall, VPN connections kept dropping, and we kept getting logged off the firewall web interface. It turns out the config file got corrupt (apparently due to the block lists). In a rush to get the firewall back inline, we were not able to save the config file at the time to review it. What fixed it was downgrading and upgrading again.
My question is - has anyone else run in to issues due to the dynamic block lists?
I'm wondering if this was just a fluke thing or if there are issues with the block lists.
Future plans include making sure the block lists we use are in the proper format.
