Ports for GVM -behind firewall

Hello, which ports does Openvas/GVM needs for scanning? My GVM is in the DMZ and I would like to scan hosts in the intranet. Ty

That is not a good idea, your session table could fill up with negative effects even if you allow all TCP/UDP Ports. I would place it “outside” your Firewall. Scanning though firewall will slowdown your scan, produce false negative and might impact your firewall.
