GXE502X User Manual 7/9/2008

oWAN-side Access and Security:

Accessibility and Security for management are considerations for whether or not to enable or disable HTTP/Telnet access from the WAN-side of the GXE502X. The default setting for WAN Side Http/Telnet Access is YES. At the default settings UPNP is turned OFF, but PPTP, IPSEC and L2TP VPN are enabled (pending).

oUsing Dynamic DNS:

If the WAN-port IP of the GXE502X is dynamically assigned by your ISP, the GXE502X can use Dynamic DNS to obtain a fixed domain name which is always synchronized with the IP address of the GXE502X. Enable Dynamic DNS by setting the DDNS Active setting to Enable and setting the DDNS ISP type, site name, and account and password in the provided fields. If not using Dynamic DNS, set the DDNS Active setting to Disable.
