We have a Fortigate 100D, firmware 5.4.6.
We are in the process of changing our ISP. Our older ISP is plugged into WAN1. We set up the new ISP to WAN2. Everything was working correctly so we unplugged the ISP from WAN1 so everything would go through WAN2. The next day all the internal users were having problems getting to the internet. When we checked the firewall, our subscriptions (support contract, IPS & Application control, Antivirus, webfilter, anti-spam) were all "unavailable".
So we ended up putting the older ISP back and after a while, the licenses started reappearing. and the FW worked normally.
It seems like the FW is trying to go out WAN1 to determine if the licenses are valid. But I don't know what else it can be.
Anyone have this problem? and is there a solution?
