Rulebase Updates

SNF Updates stopped working after installing a firewall (cisco asc). I can still force an update if I touch UpdateReady.txt and run the getRulebase script, but I'd like to fix this and go back to it being automatic.

Most likely the firewall is interrupting your SYNC sessions. About once per minute SNF will connect to our SYNC server to get updates for GBUdb data and check for rulebase updates. Normally SNF connects to our SYNC server on port 25 (SMTP). However the protocol is proprietary so some firewalls may break the connection if they don't see normal SMTP traffic.

One solution that often works is to change SNF's SYNC settings to use port 80.

<sync secs='30' host='sync.messagesniffer.net' port='80'/>

If that doesn't work then you will have to adjust your firewall to allow outbound connections to our SYNC server without inspecting them -- either on port 25 or on port 80.
