Standard setup Cisco 5505 with an exchange server
I am pretty new to routers and all that entails and I have a big problem that is really bothering me. I'm using a standard setup cisco 5505 with an exchange server that clients can access internally using an IP (10.x.x.x) and from the outside using an IP that my ISP assigns.
When inside, I can´t access the external IP. It won´t let me ping or tracert. If needed I could activate the access if I but that is not really the issue. I just introduced a wireless-router to this existing config and everything seems to be working well. However, when people connect to the router they obviously can´t see my mail using the external connection as they are part of the network.
How do I assign IPs given out by the router access to my mail. This has become a problem because mobile phones trying to access externally try are trying to go through the internal network and they are not able to do that.
Hopefully this makes sense to you and you can help me.
