Re: Cisco 1720 router & OWA

Tech-Archive recommends: Speed Up your PC by fixing your registry



You need to setup NAT and permit port 443 in from the Internet facing
interface. OWA runs on 443 if you installed an ssl cert. I'll assume you
did.

To setup the nat translation do something like this:

ip nat inside source static tcp 10.10.10.10 443 4.4.4.10 443

10.10.10.10 is your Exchange server's IP
4.4.4.10 is the fully routeable IP from your ISP that you want to map to
your exchange server

To setup the ACL:

access-list 112 permit tcp ay host 4.4.4.10 eq 443
access-list 112 deny ip any any

To apply it to the interface (assuming fa0/1 faces your ISP)
int fa0/1
ip access-group 112 in

Hello Everyone,

First of all I want to thank you everyone in advance for any assistance
you give. I am a total newbie when it comes to Cisco routers. I have
used and configured several routers in the past, however this is the
first Cisco router I have ever worked with before.
I have recently started working at a new company that has a Cisco 1720
router setup and running smoothly; we have a Windows 2000 server
running exchange. I would like to setup Outlook Web Access so that
employees can check their email remotely (from home or any other
internet-based PC)
I can access Outlook Web Access internally via web broswer:
http://servername/exchange

I can log into my router and that is about it; anything after that I do
not know how to do. The research that I have done and based on my
passed knowledge, Outlook Web Access runs over port 443; is this
correct?

What I need, is assistance with setting up my router configuration to
allow access to exchange server (OWA) externally. The previous IT
person left me notes stating that the router is using NAT if this helps
at all.

Thank you again
