Hi,

We are changing broadband provider that also will change our IP address.
Okay I have to adjust the fire wall settings but will this have anything to do with our SBS 2003 server and Exchange like certificates and so on. (I dont think so as all incomming will be routed by the router)

I need to change our mail.domain.com IP for the pushmail and remote access
inform our block mail fassility of the  IP change

Please advice of any thing else to be checked ...

Thanx..

Perhaps DNS forwarders if being used, change to new ISP dns servers (using previous ISP dns servers may or may not work).

MX Records unless someone else handles your email filtering perhaps?

If you are doing nat on the router incoming should be fine. Does your outgoing point to the router for natting or does it point directly to the ISP?
If it just points to the router, you should be good to go once all of the DNS entries are changed. (this takes a few hours to replicate around the world).
