Dear gcheria,

Thanks for you reply, currently I have only one connection with one IP public from ISP and I was successful did the NAT to allow from outside to inside_server. But, I need the same by allow my client behind ISR 4321 to access to server via public IP instead of login direct to server. Please check on the diagram for more detail.

Thanks and Best regards,

Sokmeng,

This is the related url I could find. Please check this -https://supportforums.cisco.com/t5/wan-routing-and-switching/issues-with-nat-on-a-brand-new-isr4321/td-p/2814990

communities.cisco.com is mainly for API related discussions and support forums is the best place for configuration related issues. I think your question is related to configuration of NAT . Hence request to post the question on support forum.

Thanks and Regards,
