[c-nsp] IPSEC site to site

[M K]

Hi all , I am trying to simulate IPSEC VPN on GNS3R3 f1/0 - R1 f2/0 - R1 s1/0 - R2 s1/0 - R2 f2/0 - R4 f1/0
Below is my configuration
R1crypto isakmp policy 1 encr aes 128 hash sha authentication pre-share group 2 lifetime 86400crypto isakmp key cisco address 192.1.12.2 no-xauth!!crypto ipsec transform-set SET esp-aes esp-sha-hmac!crypto map MAP 1 ipsec-isakmp  set peer 192.1.12.2 set transform-set SET  match address 100
access-list 100 permit ip 192.168.13.0 0.0.0.255 10.1.24.0 0.0.0.255 
int s1/0crypto map MAP
R2!crypto isakmp policy 1 encr aes 128 hash sha authentication pre-share group 2 lifetime 86400crypto isakmp key cisco address 192.1.12.1 no-xauth!!crypto ipsec transform-set SET esp-aes esp-sha-hmac!crypto map MAP 1 ipsec-isakmp  set peer 192.1.12.1 set transform-set SET  match address 101
access-list 101 permit ip 10.1.24.0 0.0.0.255 192.168.13.0 0.0.0.255
int s1/0crypto map MAP
I got the message *Sep 15 14:29:07.255: %CRYPTO-6-ISAKMP_ON_OFF: ISAKMP is ON
But nothing is working R3#ping 10.1.24.4Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 10.1.24.4, timeout is 2 seconds:.....Success rate is 0 percent (0/5)
