Novell, Open Enterprise Server, netware 6.5 sp6, Change IP address??

My ISP is going to upgrade our service. We are using DSL upgrading the speed of our Internet. They said we might/will have to change our IP address after the upgrade. I am new to Novell and have never done this, so i am wondering what/how i will need to perform the task.

We have a Dell PE 2800 server with 2 gigabit nics. This server runs GW and BM. One is configured with the external ip and the other configured with an internal ip for our LAN. We also use Bordermanager for our firewall and i am not too familiar with that either. Dont know if i will have make any changes there also?

Can someone point me in the right direction?

The external NIC's IP address will have to change, if the IP address changes.

You'll need to make sure the public name server address won't be changing too.

If you only have one public IP address then you're probably going to have to make changes to GroupWise, and to BorderManager for whatever settings relate to GroupWise.

Hard to say for sure because there are a couple of ways you might have it configured, but my guess is you're using the BorderManager mail proxy if you have only one public IP.

First, you want to pin them down to something a bit firmer than "might."  You'll have to have a solid confirmation of whether a change is coming, and what the change will be.  Regardless of whether you host your own public nameserver or have your ISP host it, if the IP changes then all the public DNS records have to change to match.  If DNS won't resolve the right address for your MX server for example, you won't get any email.
Also, with Bordermanager, if you have anything address-specific in your filter exceptions (as opposed to interface-specific) those firewall exceptions will have to be modified too.

We have Groupwise running but not for Internet email, just interoffice.
