random problems with Forwarding=off

[Siavash Sameni]

Hi ,
I've added one node to my tinc mesh , with forwarding off , and the network
got splitted into several pieces !!,
the thing is that , the node with forwarding off is connected to all hosts
, directly with connect to ,
and seems like that for some nodes the shortest path , that the tinc
network can find is through the node with forwarding off ,
here are the results of my first ping to all my hosts with the host with
forwarding off present :
 ./monitorhosts
Host : 10.0.113.3 is down (ping failed) at Fri Mar 16 13:36:57  2012
Host : 10.0.128.3 is down (ping failed) at Fri Mar 16 13:37:43  2012
Host : 10.0.130.3 is down (ping failed) at Fri Mar 16 13:37:59  2012
Host : 10.0.132.3 is down (ping failed) at Fri Mar 16 13:38:05  2012
Host : 10.0.138.3 is down (ping failed) at Fri Mar 16 13:38:34  2012
Host : 10.0.141.3 is down (ping failed) at Fri Mar 16 13:38:43  2012

if i switch off the node with forwarding=off , the result is as follows :
./monitorhosts
Host : 10.0.113.3 is down (ping failed) at Fri Mar 16 13:39:28  2012
which is flawless (don't mind 113) ,
when i reconnect the node with forwarding=off , the result changes to the
following :
./monitorhosts
Host : 10.0.113.3 is down (ping failed) at Fri Mar 16 13:44:49  2012
Host : 10.0.141.3 is down (ping failed) at Fri Mar 16 13:46:06  2012
. :D
when i try to ping 10.0.114.3 i receive the following :
ping 10.0.141.3
PING 10.0.141.3 (10.0.141.3) 56(84) bytes of data.
>From 10.0.141.3 icmp_seq=1 Destination Net Prohibited
>From 10.0.141.3 icmp_seq=2 Destination Net Prohibited
.
the tinc version is 1.0.16 , running on centos 5.
if anymore information needed i'd be happy to help ,
also i should mention that , i have no problem reaching the nodes from the
node with forwarding off .
i have around 64 nodes in my tinc mesh ,
i remember our previous admin told me that , when he made full mesh ,
(connectto to everwhere) , the network became unstable , is there a limit ?
should we experience slowdowns or something as the nodes grow ?
thank you.
