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, ...)
