i have Cisco ASA 5510 , i have one server published to internet with IP 188.8.131.52 which natted to private ip 10.0.0.1 " server private ip" . I need to open communication by enable " ping ,and https 'from public IP address 184.108.40.206 to my private ip " 10.0.0.50" where 10.0.0.50 is user ip and it behind proxy for internet access , so i need to communicate with 220.127.116.11 using my private ip 10.0.0.50.
note : 10.0.0.50 uses proxy to access internet , and its public ip is 18.104.22.168 .
Below is what I understand, correct me if I am wrong.
You have a server with private IP 10.0.0.1 which is published to internet with ip 22.214.171.124
You want to access the services from the published server using public IP from IP 10.0.0.50 and has internet access through a proxy server.
Question. - Are these IPs 10.0.0.1 and 10.0.0.50 shares the same internet link ? Or the proxy server has a different internet link ??
Yes , that is my goal . I need to access 126.96.36.199 by my ip lan ip 10.0.0.50 . For your question , u are correct they share same internet ISP .
OK, so NAT Loop back is your option.
Do the below.
static (inside,inside) 188.8.131.52 10.0.0.1 netmask 255.255.255.0
This will make the public IP available in LAN also.
I assume that there must be 'static (inside,outside)' statement and an ACL permitting traffic on the public IP on required ports from outside.
Rate if you find this helpful
Do you have an ACL configured to allow traffic from outside to inside on the required ports, applied on outside interface in 'in' direction ??
