Cisco 1841

Hi guys, I'm having a problem here that I hope the experts here can help me out on.

Currently, I have an Exchange server sitting on my LAN behind a Cisco 1841 (IOS v12.4 1c) which has a public IP address, meaning you would be able to access the SDM via the IP address (Insecure, I know).

Anyway, I would like to re-direct queries to the IP address to my Exchange OWA, but I am not sure how I would accomplish this using the Cisco 1841's SDM.

OWA is accessed via httpS:///exchange'

to forward https do

ip nat inside source static tcp 1.1.1.1 443 interface e0 443

ip nat inside

ip nat inside source static tcp x.x.x.x 443 interface e0 443

whrere x.x.x.x is ip address of your Exchange server

Hi Alekseev,

I understand the part about NAT, but OWA is accessed via 'http:///exchange', so how would forwarding the SSL port to the server IP address get around this?

I understand that there are ways for me to allow users to access OWA by directly accessing the server IP address, but assuming if I do not go by that route, are there no other alternatives?

Thanks!

Re: Cisco 1841

Hi Alekseev,

Ah! It's beginning to dawn upon me now. So what you're saying is, since OWA is listening on the SSL port, we would just re-direct all OWA SSL queries to the SSL port for the internal IP address of the server itself?

BTW, that was a typo in my previous post; I mean to put https://... thanks for correcting me!

Correct...
