tinc bridge inner amazon ec2 local segments

[=?ISO-2022-JP?B?GyRCQjkbKEIgGyRCfFsbKEI=?=]

Hi tinc team,

 I am a new user of tinc, and wanna use it inner amazon ec2 for bridging
different network segments.
 First, I wanna try the most simple things, just build a p2p tunnel between
two ec2 instance with segment 10.0.101.0/24.

 I can see the tunnel is established by doing

 lsof -i:655
##############
COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
tincd   2893 root    7u  IPv4  11489      0t0  TCP
ip-10-146-74-200.ap-northeast-1.compute.internal:34504->ip-10-146-159-245.ap-northeast-1.compute.internal:tinc
(ESTABLISHED)

and

 tail /var/log/syslog
##############
 Connection with vpn2 (10.146.159.245 port 655) activated (vpn1 server)

 but I can not ping each other with ip 10.0.101.10(vpn1 server),
10.0.101.12(vpn2 server)

 hope anybody can provide some advice.
 Thank you in advance.
