dear all,

i want to run 3 node DTN (raspberry pi) in 2 hop toplogy scenario.
node 1 - node 2 - node 3
node 1 is not directly connected to node 3. so, if node 1 want to commmunicate to node 3 it should be through node 2.
The problem is node 2 can not forward the bundle to node 3. so, when i ping node 1 to node 3, the result is timeout. which part of ibrdtn.conf file configuration that should edited?

this is my current ibrdtn.conf configuration

local_uri = dtn://dtn-node2.dtn
discovery_address = 255.255.255.255
discovery_announce = 0
net_interfaces = wlan0
net_wlan0_type = tcp                 
net_wlan0_interface = wlan0          
net_wlan0_port = 4556               
routing = prophet
routing_prefer_direct = yes

#node 2
static1_address = 192.168.10.12                        
static1_uri = dtn://dtn-node2.dtn   
static1_proto = tcp               
#node 1
static2_address = 192.168.10.11                 
static2_uri = dtn://dtn-node1.dtn   
static1_proto = tcp  

time_reference = yes
time_synchronize = yes
time_discovery_announcements = yes

in your opinion, what's wrong with my configuration? what it should be?

Thanks,
Rifqi
