we have a SA520W with the latest firmware. It works as an Internet Gateway and VPN concentrator. We use SSL VPN feature. Earler we have used IPSEC VPN, but the follownig experience was the same.
Everything works well for some days after system cold restart. However after some days (approx. a week) the CPU usage gets high, and the users can't establish new VPN tunnels. At this time, the management console is very very slow, and we can1t restart the system through the web console. We have to use cold restart. After restart everything starts again.
Can anybody give me any advice about this problem? This is very annoying thing.
