I’ve been going round in circles for the last few days trying to accomplish this:
I’ve not had much experience with cisco routers, this is a ASA 5510 running 8.2 (old command structure).
In a nutshell I want to translate a LAN request for one of our external ips to the internal webserver (I think this is also called hair pinning).
We have a block of 8 external IP’s
i.i.i.97, 98, 99, 100, 101, 102, 210, 211
Our interface running config is:
interface Ethernet0/0 nameif OUTSIDE security-level 0 ip address 126.96.36.199 255.255.255.248 ! interface Ethernet0/1 nameif INSIDE security-level 100 ip address 10.22.16.25 255.255.240.0 ! interface Ethernet0/2 no nameif security-level 50 no ip address ! interface Ethernet0/2.23 vlan 23 nameif GuestWireless security-level 10 ip address 172.22.225.1 255.255.255.0 ! interface Ethernet0/3 shutdown no nameif no security-level no ip address
On the inside I have a server on 10.22.16.34 which I want to expose ports 21, 80, 8000, 8082 to internet clients. However I need internal LAN clients when requesting the external IP i.i.i.98 to be redirected to 10.22.16.34
I’ve tried lots of guides but run into problems each time, I would be very grateful for some guidance.
