Internet / Remote Access
Posted on 2006-11-22
We have an Exchange server and is using most of the benefits (shared contacts, calendars, etc) ..
We want to open the Exchange server on the internet and want the best and most secure option available ..
I believe opening Exchange for "full Exchange features" will become too slow over the internet and could be more susceptible for virus and hacking attacks.
A thought is to open Exchange only for I-MAP from the internet, and only use the full functionality (contacts, calendars, etc) over the local-LAN.
I have the following questions, which should be able to help us determining the best solution:
1. Is it possible to run "full-Exchange" features over the internet without sacrificing security and operation-speed?
2. I read an article where Microsoft suggests a "front-end" and "back-end" Exchange server - for security ..
For which scenario will this be advised?
3. Will Exchange be happy with I-MAP access (from the internet) and normal Exchange access from within the office? Which ports should we open on the firewall for I-MAP to be operational?
Any help and advise will be highly appreciated.
