VPN Passthrough (SPA122 Only)

Use the Network Setup > Advanced Settings > VPN Passthrough page to
configure VPN passthrough for IPsec, PPTP, and L2TP protocols. Use this feature if
there are devices behind the ATA that need to set up IPsec tunnels independently.
For example, a device may need to use a VPN tunnel to connect to another router
on the WAN.
By default, VPN Passthrough is enabled for IPsec, PPTP, and L2TP.
To open this page: Click Network Setup in the menu bar, and then click
Advanced Settings > VPN Passthrough in the navigation tree. After making
changes, click Submit to save your settings, or click Cancel to abandon any
unsaved entries.
