Scan-to-folder fails after firewall installation

cercoedo

Hello,

I've just installed a USG20W-VPN firewall.

I have updated the network settings on all devices with the new parameters (IP, GATEWAY, DNS) but I have a problem with network scans. 

On 2 different MFPs (OKI MC853 and CANON IRADV400i) the scans-to folder function no longer work.

Network scan destinations are set with the host name of the machines as DHCP is enabled (e.g. \\ machine-name \ scans)

The problem detected by the multifunction is "unable to connect to the DNS server"

On the multifunction devices the configuration is static IP with Gateway and DNS = IP firewall address.

I tried to configure the destinations of the folders with IP address of the machines instead of the host name (ex: \\ 192.168.x.x \ scans) and the error message is "could not find the server".

I've created a Service Object to enable the port used by multifunction devices.

If I disconnect the firewall and restore the old configuration by connecting the devices directly to the router, everything works perfectly.

Thank you

Can I know the IP address of MFPs are the same subnet as PC's which connect to?
If so, you can try to enable Allow Asymmetrical Route, and check it again.

Hi Charlie, 
thank you for your answer. 
Here is the network interface condfiguration of the MFPs:
IP: 192.168.10.x
SUBNET: 255.255.255.0
GATEWAY: 192.168.10.1 (Firewall IP)
DNS1: 192.168.10.1 (Firewall IP)
DNS2: 8.8.8.8

I'll try to enable Allow Asymmetrical Route and let you now. In the while I've also try to set up scan to mail function but I receive an error but probably it is causeb by Office 365 authentication method.

I think you should set the Email configuration on MFPs.
