This week I installed and configured the SA520 device on our network. Today several members of the business have complained to me that pages will intermittently not load for them. There's no rhyme or reason for the page - MSN start page, web banking, whatever. A browser refresh will usually fix the page load issue. When running a linux firewall before getting the Cisco (aka Delta) hardware installed, my users had not experienced any connectivity issues. I'm certain it's not a problem with our fiber Internet connection.
I'm running firmware 1.1.21 with no URL filtering whatsoever. My DNS records are pointing to OpenDNS for speedy lookups.
Can you post the config and discribe a bit about the topology?
Topology: Using a static IP address provided by my fiber ISP. Internet traffic coming in on a dedicated VLAN 784 as provided by the ISP which terminates to a Cisco WS-2950 switch. Through port programming, the connection traverses to the SA520 router and gets dumped back into the switch which then services the LAN connections.
Users have only noticed that the HTTP connections are not solid. It could very well be DNS issues causing the problem. Generally I don't get users contacting me when their streaming radio goes down so I can't tell if it's a WAN, TCP port, or DNS. I'm simply comparing the setup I had with a Linux firewall (m0n0wall) I had set up as a temporary measure while I was waiting for the router to arrive and no one complained about the Linux setup.
