I have configured Static NAT to forward port 443 to 192.168.0.3 internal IP address as follows:

ip nat inside source static tcp 192.168.0.3 443 interface Dialer1 443

However, I see "Page Not Found" when I try to access it with a web browser over port 443 (internally and externally). I have also checked online port forward tester that port 443 is closed. I don't have any issue accessing server on 443 internally.

P.S. I am not Cisco expert and this router has been configured by previous IT guys so I might not know everything configured in this config.

Please see following config:

  • Does any other traffic from your "OUTSIDE_IN" ACL make it through, or is it only port 443 that fails? EDIT: To clarify, I think your Gi0/1 interface may not be properly processing that ACL, since the Dialer1 interface is assigned the IP address and NAT configuration...but I could be wrong. – Panther Modern Nov 12 '13 at 19:30
  • Did any answer help you? if so, you should accept the answer so that the question doesn't keep popping up forever, looking for an answer. Alternatively, you could provide and accept your own answer. – Ron Maupin Aug 8 '17 at 15:01

The "OUTSIDE_IN" ACL should be applied to the Dialer interface rather than the Physical Gigabit 0/1 interface.

log in and run the following:

enable
configure terminal
interface G0/1
no ip access-group OUTSIDE_IN in
interface Dialer 1
ip access-group OUTSIDE_IN in
exit

I would recommend having a consultant take care of your DMVPN, ACL rules, and static NAT. Just by looking at your configuration I can tell that you may need some security specialist help.

  • Hi John, thank you for answering, and welcome to NE. I edited out the credentials at the bottom of your answer, since that information should be included on your "about" page in your user profile – Mike Pennington Nov 13 '13 at 15:52
