Why ping some IP addresses of the other side of EoIP tunnels response timeout?

Greetings,
There’s a wired problem I really don’t know how to resolve it.
Two routers connected though EoIP tunnel.
Router One for 192.168.0.0/24 (local dhcp network)
Router Two for 192.168.1.0/24 (local dhcp network)
Both router version is 6.37.3
Setting up EoIP tunnel for the two routers is to let the networks can contact each other. ( ex: 192.168.0.5 < ---- > 192.168.1.3 )
There’s no relative bridge settings , just add routes in order to achieve it.
Here’s the problem:
192.168.1.0/24 ping some of the IP of 192.168.0.0/24 response timeout.
So far I know 192.168.1.0/24 ping 8 IP address of 192.168.0.0/24 response timeout.
How can I resolve it , please give me advice .

Once i was doing mpls and vpls tunnels and had to enabe multicast helper if using wireless as the tunnel protocol uses multicast which can have trouble on 802. Not sure if that’s related to your problem but might be worth trying.

Hi estar , thank you for replying me. I’m sorry . I don’t understand it. I don’t know what multicast is .
However , if I don’t assign the out interface of the NAT rule of Masquerade . The problem solved. I don’ know why and have no idea.
According to this article :http://wiki.mikrotik.com/wiki/How_to_configure_a_home_router I should assign the out interface of the masquerade rule.
Shouldn’t I assign the out interface?

Yeah you can ignore my first answer I think I misunderstood your question. I think the problem is that you don’t want to masquerade the tunnel traffic as both are on different subnets so should work without the masquerade. Just masquerade the main Internet connection.
