I'm not able to ping from PC(1) to PC15(1) across the IPSec VPN Tunnel that I have set up. I have used the configuration given in the documentation of Cisco.
R1(config)# crypto isakmp policy 10
R1(config-isakmp)# hash sha
R1(config-isakmp)# authentication pre-share
R1(config-isakmp)# group 5
R1(config-isakmp)# lifetime 3600
R1(config-isakmp)# encryption aes 256
R1(config-isakmp)# end
R1(config)# crypto isakmp key cisco123 address 10.2.2.1
R1(config)# crypto ipsec transform-set 50 esp-aes 256 esp-sha-hmac
R1(cfg-crypto-trans)# exit
R1(config)# access-list 101 permit ip 192.168.1.0 0.0.0.255 192.168.3.0 0.0.0.255
R1(config)# crypto map CMAP 10 ipsec-isakmp
R1(config-crypto-map)# match address 101
R1(config-crypto-map)# set peer 10.2.2.1
R1(config-crypto-map)# set pfs group5
R1(config-crypto-map)# set transform-set 50
R1(config-crypto-map)# set security-association lifetime seconds 900
R1(config-crypto-map)# exit
R1(config)# interface S0/0/0
R1(config-if)# crypto map CMAP
R1(config)# end
Please help to solve this.
Thank you :")
