Local Content and Advertising Links

DNS Proxy
With DNS proxy, the VSG provides DNS redirection when a subscriber’s configured DNS server is behind a firewall or located in a private Intranet.
NAT (Network Address Translation)
NAT (RFC 1631) is the translation of the IP address of a host in a packet, for example, the source address of an outgoing packet, used within one network to a different IP address known within another network.
The VSG automatically performs NAT on the LAN. You can also set the VSG to perform NAT on the WAN for VPN (IPSec and PPTP) connections.
Static Route
Static routes tell the VSG how to forward IP traffic when you configure the TCP/IP parameters manually and disable NAT.
