Problem with DFL-1600
« on: January 22, 2010, 09:04:45 AM »
Hi

I have a few web servers behind a DFL-1600 and noticed that as of approximately 08 January certain users are blocked from accessing the server when trying to post from certain browsers/user agents.
We have changed nothing on the servers or the firewall so are thinking something changed automatically on the firewall.
Does anybody know what can cause a DFL1600 to block certain user-agents for 30-60 seconds (before posting, ping to server works, but as soon as the users in question post their pings time out for 30-60 seconds).
