Features in Gateways

This topic provides information about specific features you can use to configure Gateways in ActiveTransfer:

Antivirus Scanning

You can configure an ActiveTransfer Gateway instance to connect to an Internet Content Adaptation Protocol (ICAP) server, which is, configured for antivirus filters that suit your organization's requirements. Each ActiveTransfer Gateway instance can have only one ICAP server configured. If you have multiple ActiveTransfer Gateway instances, you must configure the antivirus scan settings on each instance.

The pre-requisites to configure the antivirus scan settings on each instance are:

Configuration of the JVM memory in ActiveTransfer Gateway.

ICAP server must be accessible from ActiveTransfer Gateway.

Service Configuration for ICAP Server

You can specify the virus scan service name of the ICAP server and the run-time parameter values to send to the ICAP server in the following format: service name?parameter1 value&parameter2 value&parameter3...

Here, ... indicates any additional parameters that you might want to include.

For example, the c-icap server's virus service expects the following parameters virus_scan?allow 204=onforce=on sizelimit=off mode=simple

Where:

allow 204=on enables 204 (no content) responses outside previews for virus scan if the ICAP client does not support it. If the 204 response to the virus scan request is No modification needed indicates that no virus was found in the file.

force=on enables the scan of the file even if its file type is not included in the srv_clamav.ScanFileTypes directive in c-icap.conf file.

sizelimit=off enables the virus scan service to ignore the srv_clamav.MaxObjectSize directive in c-icap.conf file.

mode=simple enables the 204 response only when no virus is found and an error message if a virus found.

For more details on the parameters you can use, see the ICAP server documentation.
