Remote VPN Support

[Jake Rybak]

I am trying to use sipinspector remotely over a client VPN (Cisco AnyConnect). The local_ip of the VPN adapter is displayed as an option in the initial screen. However, once a scenario is run, it always uses the ethernet interface. Wireshark shows that the INVITE is not sent over the VPN tunnel.

Thank you.

SIP Inspector has no means to pick which interface the message will go out on. It is left to the OS (which tends to do a good job). In your case, I would recommend to temporarily disable other interfaces not need to make traffic. Once you get messages going you can bring up other interfaces again. Try that and see how it goes.

There is only one interface on the box which is eth0, so that cannot be disabled. The VPN interface is brought up as soon as the connection has been established.

Even if I do not use the [local_ip] variable and use a hardcoded IP it still sources from the wrong IP.

Variable and hardcoded local_ip set to: 172.28.4.97

From SIP logs:

From:172.16.199.140:5060 - To:10.47.46.7:5060    11:07:36.484

Maybe you send me the following info to email directly (rather then posting it publicly). 

a) Can you print starting screen shot where I can see IP addresses offered.

b) Output of command 'ipconfig /all'  ('ifconfig' on Unix)

c) Output of 'netstat -a -p UDP -n'  ('netstat -aun' on Unix)

That way I will get more idea what is happening?
