Manage IGMP Proxying and VPN Pass-Through
IGMP proxying allows a computer on the local area network (LAN) to receive the multicast
traffic it is interested in from the Internet. If you do not need this feature, leave it disabled it,
which is the default setting.
When Network Address Translation (NA T) is enabled in the modem router (see Manually Set
Up the Internet Connection on page 29), it filters encrypted tunnel packets through NAT,
causing these packets to become invalid. VPN pass-through allows encrypted tunnel packets
to go through without being filtered and is enabled by default for IPSec, PPTP, and L2TP
packets. Do not disable VPN pass-through for IPSec, PPTP, or L2TP unless a specific
reason exists.
To change the default IGMP proxying and VPN pass-through settings:
1. Launch an Internet browser from a computer or WiFi device that is connected to the
network.
2. Type http://www.routerlogin.net or http://www.routerlogin.com.
A login screen displays.
3. Enter the user name and password for the modem router.
The user name is admin. The default password is password. The user name and
password are case-sensitive.
4. Click the OK button.
The BASIC Home screen displays.
5. Select ADVANCED > Setup > WAN Setup.
