I have established site-to-site connection but my client has informed me that our internal IP address is conflicting with their network's internal IP address. so now they want me to create NAT policy so I can send IP address 192.168.18.2 on to the VPN and they can access my server. My server IP address is 192.168.16.2. (192.168.16.2 IP address is conflicting with their internal lan IP).
I am not sure how do I write NAT policy.
Pls find the following configuration:
crypto isakmp policy 2
encr aes 256
crypto isakmp key abc address 203.x.x.248
crypto ipsec transform-set compname esp-aes 256 esp-md5-hmac
crypto map SDM_CMAP_1 1 ipsec-isakmp
description Tunnel to 126.96.36.199
set peer 188.8.131.52
set security-association lifetime seconds 86400
set transform-set compname
set pfs group2
match address 100
access-list 100 permit ip host 192.168.16.2 host 172.16.241.31
Pls let me know how would I write NAT policy so that I can send host IP 192.168.18.2 and they can access my server data which is on IP 192.168.16.2.
Reminding you again that my client has got other range on their network which is 192.168.16.x/24.
Your quick help will be much more appreciated.
