What should i block so that Vonage would not work?

[grr]

Friends,

I want to know what ports are required to be blocked in the modem/router so that the Vonage is not able to connect.

or at least i could limit the bandwidth it is consuming, as it slows my internet like a snail.

Please help.

Thanks,

Grr configure Stateful Packet Inspection (SPI) to block netgear. Also block these ports in spi firewall.

Ports used by Vonage Adapters
The following ports are needed for OUTGOING Internet communications from the Vonage device to the Vonage servers.
DNS: Port 53 UDP
TFTP: Ports 21, 69, 2400 UDP
HTTP: Port 80 UDP
NTP: Port 123 UDP
SIP: Port 5061 UDP (used for older Vonage devices provisioned before 2005)
The following ports are needed for INCOMING and OUTGOING Internet communications from and to Vonage devices and servers.
RTP (Voice) Traffic: Ports 10000-20000 UDP. When a call is made, a random port between 10000 and 20000 is used for RTP (Voice) traffic. If any of these ports are blocked, you may experience one way or no audio.

This might help you .
