Port Forwarding--Cisco 1720 router device

Unanswered Question

Perhaps someone can help me, as I can't find a clear cut answer anywhere as to how to do, what normally would seem like a simple task.


How can I best forward http and https traffic to a host on the LAN side through a Cisco 1720?


I'm essentially just looking to setup a rule along the line of External 80 and 443--->192.168x.x 80 and 443, but I can't find a concise answer on how to do this.


I have created an access-list entry which appears to be correct, but this still does not actually seem to apply the actual forwarding.


Any help would bew greatly appreciated.

Hi


You can define the NAT statement as mentioned below..


ip nat inside source static tcp x.x.x.x 80 y.y.y.y 80


ip nat inside source static tcp a.a.a.a 443 y.y.y.y 443


Where x.x.x.x/a.a.a.a is your local inside ip address and y.y.y.y is your external ip


You can also refer the below link for more info on the same..

In other words:

ip nat inside source static tcp 192.168.x.x 80 Ethernet0 or Fastethernet0 (WAN Interface) 80
