[SR-Users] Need help in routing configuration

[Nelson Pereira]

Ok, I found out that the firewall was not setup to allow connection...

So can someone explain to me how I need to setup asterisk and Kamailio so that they both use the same interface eth0?

10.98.6.5 is Asterisk 
10.98.6.5 is Kamailio
10.98.118.20 is the UM

So basically, the connection would look like this:

Asterisk -UDP-> Kamailio -TCP-> UM


So how can I setup all this this way?

I do not know if having 2 identical routes via 2 different infterfaces 
can cause any problems. Just for testing I would remove one of the 
redundant routes just to find out if causes a problem.

Further, for testing remove all iptables: iptables -F

Further, Kamailio logs that it is trying to establish a TCP connection 
but it fails. Thus, use tcpdump/wireshark to verify if Kamailio really 
tries to create a TCP connection. Use 2 tcpdump processes and capture 
eth0 and eth1 separately. Then analyze the tcpdump and watch for the SYN 
messages. Analyze on which interface they are sent. Analyze the source 
IP address of the SYN packages. Are there any TCP responses from the 
other party?

Try to start with a simple setup - e.g. only 1 IP address, and only if 
it works then make the setup more complex (multiple IP addresses, 
multiple routes, ...)
