NETGEAR ProSafe SSL VPN Concentrator 25 SSL312 Reference Manual
Port Forwarding 10-3
v1.0, August 2006
Configuring Host Name Resolution
Once all the server and port information has been configured, remote users will be able to access
private network servers using Port Forwarding. Since users will need to remember the complicated
IP addresses of your network servers, the SSL VPN Concentrator administrator can also specify
host name to IP address resolution. Once configured, users will be able to access TCP applications
at familiar addresses such as “mail.mycompany.com” or “ftp.mycompany.com”.
To add a host name for client name resolution:
1. Enter an IP address in the Local Server IP Address field in the Configured Host Names for
Port Forwarding section. The address should already be defined in the Configured
Applications for Port Forwarding table.
2. Enter a domain name of the internal server in the Fully Qualified Domain Name field.
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.
