I have discovered this weird issue. We have a Dell Sonic Wall NSA-2600 Firewall / Router Installed. We discover an issue when we try to navigate to www.suntrust.com
and it says the site can't be displayed. This appears to happen randomly but if we reboot the Sonic Wall NSA-2600 we can access www.suntrust.com
for a short period of time before it won't allow access any longer.
We have checked switch settings, dns server responses, etc.
Can't figure this one out and any help would be greatly appreciated.
