Configure ALG settings

Advanced > NAT > NAT ALG
A Virtual Private Network (VPN) is a network that uses a public network, such as the
Internet, to provide secure communications between a remote computer or network
and another network. Some offices often provide VPN access to their networks to
enable employees to work from their remote office/home office, or while traveling.
If your office or place of work has allowed and authorized access for you to access their
network through VPN, the default VPN settings in your router have been configured to
pass through the most common types of VPN protocols, which typically do not require
any additional configuration changes.
1. Log into your modem router management page (see "Access your modem router
management page" on page 23).
2. Click on Advanced, and click on ALG.
3. Review the settings and click Apply to save settings.
