Re: [SR-Users] Need help in routing configuration

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?

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, ...) regards klaus
