Hola
Neceitba abrir un rango de puertos a una videoconferencia SIP desde la WAN a la LAN.
Los puertos que tengo que abrir son
1720 TCP
3230-3248 TCP
3230-3305 UDP
5060 TCP
5060 UDP
5070 TCP
Para ello he configurado en el router Cisco 1800
ip nat inside source static tcp 192.168.0.169 1720 interface FastEthernet4 1720
ip nat inside source static tcp 192.168.0.169 5060 interface FastEthernet4 5060
ip nat inside source static udp 192.168.0.169 5060 interface FastEthernet4 5060
ip nat inside source static tcp 192.168.0.169 5070 interface FastEthernet4 5070
access-list 110 permit tcp host 192.168.0.169 any range 3230 3248
access-list 110 permit udp host 192.168.0.169 any range 3230 3305
route-map RADVISION permit 10
match ip address 110
ip nat inside source static 192.168.0.169 85.85.85.85 route-map RADVISION extendable
Pero no funciona
Segun indica el fabricante
You can configure the TCP or UDP port range by setting the base port, which is the lower end
of the port range (if, for example, port 3230 is busy).
The SCOPIA XT Series uses dynamic TCP ports 3230-3248 for the following:
• H.225.0: An H.323 protocol that specifies the messages and procedures used by
gatekeepers to set up calls.
• Q.931:A telephony protocol used for establishing and terminating the connection in H.323
calls.
• H.245: A Control Protocol used for multimedia communication; enables transferring
information about the device capabilities, as well as opening/closing the logical channels
that carry media streams.
• SIP: A signaling protocol used for creating, modifying, or terminating multimedia
connections between two or more participants.
The SCOPIA XT Series uses dynamic UDP ports 3230-3248 for enabling real-time H.323 and SIP
media, including audio, video, and H.224/data (RTP), and media control (RTCP).
Estara bien configurado el router?
