I have an old router ProSafeVPN firewall FVS338. I can't figure out how to set up my HP all-in-one. All outgoing traffic is blocked on the firewall. The printer works (added rule a with port 9100) but I have a problem with starting the scanner. It's like an ordinary Twain but I have no idea how to "bite" it. Can someone tell me how to enable the scanner?
Everything should be on the same local LAN and IP subnet. Nothing is blocking services then.
if you have more networks or subnets and need to access this multi function device, something basic is wrong - the environment requires an update, the network must be redesigned or you should provide better information on how and why this firewall is in place.
