fe ature allows TW - EA510v 3 (c) & 3G/4G automatically reconnect to the ADSL connection when it ’ s
restored, reducing connection costs.
The TW - EA510 v3 (c) & 3G/4G router complies with ADSL2+ standards for deployment worldwide
and supports downstream rates of up to 24 Mbps and upstream rates of up to 3,5 Mbps. Designed
for small office, home office and residential users, the router enables even faster Internet
connec tions. You can enjoy ADSL services and broadband multimedia applications such as
interactive gaming, video streaming and real - time audio much easier and faster than ever before.
The TW - EA510 v3 (c) & 3G/4G supports PPPoA (RFC 2364 – PPP (Point - to - Point Prot ocol) over
ATM Adaptation Layer 5), RFC 1483 encapsulation over ATM (bridged or routed), PPP over
Ethernet (RFC 2516) to establish a connection with your ISP. Your new router also supports VC -

The perfect solution for conne cting a small group of PCs to a high - speed broadband Internet
connection, the TW - EA510v 3 (c) & 3 G/4G allows multiple users to have high - speed Internet access
simultaneously.
Your new router also serves as an Internet firewall, protecting your network from access by outside
users. Not only does it provide a natural firewall function with Network Address Translation (NAT), it
also provides rich firewall features to secure your network. All incoming data packets are monitored
and filtered. You can also configu re your new router to block internal users from accessing the
Internet.
The TW - EA510 v3 (c) & 3G/4G provides two levels of security support. First, it masks LAN IP
addresses making them invisible to outside users on the Internet, so it is much more difficult for a
hacker to target a machine on your network. Second, it can block and redirect certain ports to limit
the services that outside users can access. To ensure that games and other Internet applications
run properly, you can open specific ports for outsi de users to access internal services on your
network.
The Integrated DHCP (Dynamic Host Control Protocol) client and server services allow multiple
users to get IP addresses automatically when the router boots up. Simply set local machines as a
DHCP client to accept a dynamically assigned IP address from the DHCP server and reboot. Each
time a local machine is powered up; the router recognizes it and assigns an IP address to instantly
connect it to the
LAN.
For advanced users, Virtual Service (port mapping ) functions allow the product to provide limited
visibility to local machines with specific services for outside users. For instance, a dedicated web
server can be connected to the Internet via the router and then incoming requests for web pages
