Port forwarding is not working on CISCO router

  • 772

I have installed Open VPN Access server on a ESXI server.

To access it from outside , I have added port forwarding to CISCO router using following command.

#conf t
#ip nat inside source static tcp 10.201.102.163 443 <MY_EXTERNAL_IP> 443
#ip nat inside source static udp 10.201.102.163 443 <MY_EXTERNAL_IP> 443

There were no errors or any messages after executing these commands.

But when I navigate to https://<MY_EXTERNAL_IP>, I am not able to reach access server?

Edit Result of sh ip access-list

  1. Have you assigned the inside and outside designations to the relevant interfaces ?

    Router# int G0/0
Router# ip address <private-ip> <mask>
Router# ip nat inside

    and

    Router# int G0/1
Router# ip address <public ip> <mask>
Router# ip nat outside
