Try adding a netmask and specifying 10.13.0.7 as the gateway in your routing table entry.
Caf's comment that this is a duplicate of receiving multicast on a server with multiple interfaces (linux) answered this! (And I post this as an answer for clarity.) Namely, an echo 0 > /proc/sys/net/ipv4/conf/eth1/rp_filter resolves my issue.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
