Configuring HW Firewall for modem switch?

By jfuller05 ·
Alright, I have a major question for all the Network techs. I was put in a position during the middle of a major switch for my employer. They were originally with AT&T for VOIP and internet access; now, they are switching to Dialog. We have the modems in place, ready to switch over, but of course, the Firewall has to be configured correctly before the switch. It is a SonicWall hardware firewall. The guy who was in this position before me is still going to take care of it, but Dialog and the others are really wanting to get this switch taken care of.There is a lot of things not finished when I actually took his place. He is on the road a lot so he is hard to get a hold of, but he said I could go ahead and do it. I wouldn't mind, but I don't know any of the pre-configured settings, is this difficult to do? Can someone lead me in the right direction? I have Networking knowledge, but mostly with AD, GP, simple networking.
Network running Windows Server 2008, workstations are Windows XP.

if you can look at the old one[firewall] and how it's configured. Didn't the "other guy" document anything?

I looked in the room where the server, switch, modem, and firewall are located and couldn't find anything with documentation. There isn't any documentation about how it is setup or anything. I've been reading about SonicWall and doing research about it. I thought maybe someone else had a similar problem in the past or present.

No? Mon Dieu! get the manual from SonicWalls site

find the model and go download the manual and read it.

If the network guy didn't document how the firewalls are setup, or why they are the way they are, as well as the network in general, then well, major screwup from my pov.

Other thing is, log on to the existing firewall, look at how it's configured. You'll need the user name and password and if you don't have that well another oops.

I was thinking there may not be a perfect solution to this mess. Thanks for all your help, it's appreciated. There are a lot of oops! for this situation. Documentation is imperative for IT.

look, you've got to know why something is configured the way it is

by CG IT In reply to Thanks

if you don't know why, how are you going to configure it? To know why, you have to know how the network is setup. To know that, you've got to have a broad knowledge based or a book of documentation that says this is the way it is and why it is that way.

or you could simply hire an expert consultant on firewalls. Heck SonicWall has hundreds of VARs who'll come out and configure it for a fee. But they will ask the same questions. Where's the documentation and baring that, then they will pepper you with questions on wow do you want it configured. What services do you want to be made public. What don't you want users to be able to do. Who gets remote access, what type of remote access do you want..blah blah blah blah blah.
