Hi All,
i need help.
i have configured a site to site VPN on Cisco ASA with partner who is using openswan. my configuration on ASA is as follows however traffic is not being encrypted to pass through the tunnel:
crypto ikev2 policy 60
encryption aes-256
integrity sha256
group 14
lifetime seconds 86400
----------IPsec Proposal (Transform set)--------------------
crypto ipsec ikev2 ipsec-proposal IB_PROPOSAL
protocol esp encryption aes-256
protocol esp integrity sha-256
--------Access-List for traffic to encrypt----------------------------------------------------
access-list ZECHL_IB extended permit ip 192.168.100.0 255.255.255.0 host 192.168.200.215
access-list ZECHL_IB extended permit ip host 192.168.100.18 host 192.168.200.215
--------Crypto map combining ACL, peer and IKEV2 Proposal----------------------------
crypto map TCIB_CRYPTO_MAP 1 match address ZECHL_IB
crypto map TCIB_CRYPTO_MAP 1 set peer public_address
crypto map TCIB_CRYPTO_MAP 1 set ikev2 ipsec-proposal IB_PROPOSAL
crypto map TCIB_CRYPTO_MAP interface OUTSIDE
------------------Tuunel group------------------------------------------
tunnel-group public_address type ipsec-l2l
tunnel-group public_address ipsec-attributes
ikev2 local-authentication pre-shared-key xxxxxxxxxxxxxxx
ikev2 remote-authentication pre-shared-key xxxxxxxxxxxxx
i can see incoming traffic from partner though when they attempt to reach 192.168.100.18

I have Nat exemption ticked in the connection profile. I have also ticked NAT-T in the crypto map

You need
NO-NAT ( exemption NAT) for encrypt traffic
That all I think
