Basic IPsec VPN tunnel

Hi Folks,

I stuck in this while I've been practicing basic IPsec VPN tunnel on GNS3. I've got this scenario. I have EIGRP up and running between all routers. Connectivity has been established between R1& R3.

R1(f0/0)------------R2-----------(f0/1)R3

Here is my configs:

R1

---
Phase 1 attributes:
crypto isakmp policy 1
encr aes
hash md5
authentication pre-share
lifetime 3600
crypto isakmp key CISCO address 23.0.0.3 255.255.255.0
Phase 2:
crypto ipsec transform-set MYSET esp-aes esp-md5-hmac 
crypto map MYSET 1 ipsec-isakmp 
set peer 23.0.0.3
set transform-set MYSET 
match address 100
access-list 100 permit tcp 3.3.3.3 0.0.0.255 1.1.1.1 0.0.0.255 eq telnet
int f0/0
crypto map MYSET
R3

encr aes

Phase 2:

crypto map MYSET 1 ipsec-isakmp 
set peer 12.0.0.1
set transform-set MYSET

crypto map MYSET
Any thoughts and advices will be highly appreciated!
Thanks in advance
