Using a network card

In order to connect using a network card, you need to install the network card driver and TCP/IP protocol . If your PC already has an intranet connection, you do not have to do anything to connect to your host PC from a guest PC.

The Connection Wizard can help you to check your PC's network setting.
Ping is a good tool for checking your connection. See Connection checking by ping.

| #### Firewall consideration From a security point of view, it is very important to have a firewall between an intranet and the Internet. The purpose of a firewall is to protect the corporate network against attacks or invasions from outside. The current version of Desktop On-Call does not allow access via a firewall. However, this restriction may be inconvenient. To avoid this inconvenience, you are recommended to prepare a dialup server to accept access from outside a company.
