NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual
6-8 Configuring the SSL VPN Tunnel Client and Port Forwarding
v2.0, May 2007
Configuring Host Name Resolution
Once the server and port information has been configured, remote users will be able to access
private network servers using Port Forwarding. As a convenience for users, the SSL VPN
Concentrator administrator can also specify host name to IP address resolution for network
servers. Host Name Resolution allows users to access TCP applications at familiar addresses such
as mail.mycompany.com or ftp.mycompany.com rather than by IP addresses.
To add a host name for client name resolution:
1. In the Configured Host Names for Port Forwarding section, enter an IP address in the Local
Server IP Address field. The address should already be defined in the Configured Applications
for Port Forwarding table.
2. In the Fully Qualified Domain Name field, enter a domain name of the internal server.
3. Click Apply to submit the host-to-name mapping. The IP address and domain name should
appear in the Configured Host Names for Port Forwarding table.
Now, remote users will be able to securely access network applications once they have logged
into the SSL VPN portal and launched Port Forwarding.
