Can I use Netphone2phone with a NAT (Network Address Translator) or a firewall?
A NAT is often used between private networks (like those used at home or at work) and the Internet to map a private IP address to a public IP address. Routers and software gateways (such as Internet Connection Sharing in Windows) usually also function as NATs. Firewalls, on the other hand, filter access to protected networks. Netphone2phone works with most NATs and firewalls without any additional setup. However, if your calls do not connect or you experience one-way voice, you likely have a NAT/firewall problem. In that case, you will need to ask your network administrator to open ports on the firewall or set up port mappings on the NAT.
