Q: When using the SIP proxy...
Do I need to manually then go configure the firewall to allow these ports to be
ACCEPTed??
That is, do I configure the traffic from RED, SIP port to be REDIRECTed to the
firewall host (siproxd), and then ACCEPT the SIP and RTP ports from RED?
Not clear on this, and if that's the case, why it wouldn't be configured
automatically as part of configuring the SIP Proxy screen?
Thanks,
AJ

Subject: SIP/Vonage?
OK...for those of you keeping track ;) ...I swapped my original "target host"
for another one I had lying around. This one works much better. Configured
cleanly, etc.
QUESTION:
Has anyone gotten Vonage hardware to work behind the firewall? Using SIP
Proxy, I assume? I found their tech-notes on the ports and it lists this:
===================
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: Port 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.
========================
So I see that the default Outgoing is already set for 80, 53 and 123 (I
assume via the NTP Server). I added TFTP 69, 2400 from ANY to RED.
*** NOTE: I tried setting this to "GREEN --> RED", but it put "ANY" in there.
I don't know how to set that using the "rule builder". Anyone?
Then I enabled the SIP Proxy and set the SIP port to 5061 and the RTP to
10000-20000. I Saved and Restarted the proxy.
Needless to say, it doesn't work. Does not seem to connect to the Vonage
servers.
HELP?
