Last evening, our Gateway appliance was moved behind a reverse-proxy. The reverse proxy receives requests from the internet and forwards them to the correct host. Therefore, our public IP address has changed.
I went into the core and changed the Gateway config to the new external address. Restarted the service. So far so good.
Now, I remoted into a computer off the LAN and ran an inventory and a vulscan. Good to go.
So then I tried remote control - and it failed. It had been working before the migration. I got an error "12", which I looked up to see that the certificate had expired.
I belive that the certificate has to be moved or copied to the reverse proxy, but I don't know if this is for sure, or where to get it from (the gateway? the core?) or how to install it.
I am also wondering why the inventory and vulscan worked if the remote contol didn't -- isn't the client accessing the core the SAME WAY?
I am looking for a procedure and a detailed explanation.
