In most cases no configuration is required by the client requesting support.
In some cases, where either strict regulatory compliance guidelines or proprietary firewalls are in place, some configuration is required. Typically such configuration is not done by the end user. If you have an IT Staff for your Small Business, they'd be the ones to refer this information.
The Remote Support Firewall Config is provided in the Document Resources section of our site. Have your IT Staff use this to enable Remote Support for your office.
