AS2 Firewall Considerations

Note: This section refers to your firewall settings, and not settings within VersaLex. You should contact your systems administrator with questions pertaining to your firewall.

If your server is behind a firewall and/or your trading partner's server is behind a firewall, it will be necessary to configure the firewalls to allow VersaLex to properly exchange messages with your remote trading partner. Depending on the type of firewall set up, the following settings in your firewall should be modified:

  1. Incoming and outgoing messages should be allowed from and to your remote trading partner's IP addresses or qualified host name.
  2. The port for your trading partner's remote server should be opened for outgoing messages.
  3. The port(s) that you configured for your Local Listener should be opened to allow incoming messages.
