Hello, I am in the process of setting up a firewall and need to configure so that it let's Amember communicate with Authorize.Net to run payments. I tried this before and could not get it configured right after trying to white-list Authorize.Net's IP address. If you have put up a firewall and use Authorize.Net and know how to properly configure the setting so that nothing gets in, but credit card charges get out, any help or guidance you can share to help me get this configured correctly would be greatly appreciated. Thank you.
