[SOLVED] Wireless AP, Exchange server, private switch?
« on: February 02, 2008, 11:31:07 AM »

I asked in IRC, but thought I'd ask here just so all the suggestions are in one place.

Background:

I have a Dlink wireless AP at work that has an internal IP given (set static in the AP config now) by our private management switch. This provides internet access as well as access to our internal network (shared drives) all the way up to our corporate office.

Switch: 172.16.x.x
Corp. network: 192.168.x.x
Office AP: 10.20.x.x

Internet access works fine and I can get to all shared drives up in the corporate office. The only thing I can't do is get Outlook to connect to our Exchange server up in corporate. I can ping the mail server's IP, but Outlook never connects. This is all on a wireless connection and some folks on IRC suggested I go wired to see if it's a wireless issue.

Thoughts?

I won't be able to try until Monday, so I'm just trying to gather info at this point.

I haven't used exchange much (honestly, I find it to be more of a huge hassle than any kind of help, thanks to IMAP)

When I have had router issues it generally wasn't because I was using wireless. It usually ends up being some kind of setting inside (for example, I have some weird glitch where I have to reset UDP whenever I want to use my xbox, or I have to change the encryption type to work with my (wireless) mp3 player).

I would hate to ask about the exchange server settings for obvious reasons, but are you sure they are right? I had a heck of a time setting up my computer to connect to ours at work recently. it had to be set to the internal ip with a login of .local instead of the .com, and the ip was for some reason the ip generally reserved for routers (192.168.0.1)

I don't manage the Exchange server, so I can't really telly you much about it.

However, if I connect my laptop directly to the management switch I can connect immediately. So I'm pretty sure it's something in the wireless AP holding me back.

At the risk of having little knowledge about what you are doing here, I though I'd give a little shot at helping:

Have you checked for any updates for the router you're using? I have never used a D-link wi-fi router yet, but I had trouble with my netgear, and thankfully when I finally tried to fix it, i checked for an update, and like a week prior to my checking a new firmware was made available that fixed the problem.

Nope, still trying to figure out why this isn't working.

i assume you've already checked any software firewalls that might be causing problems?
are there any settings in the exchange server that you could check out?
which os are you using?
i don't suppose that something somewhere has to know the wireless mac address to be allowed onto the (exchange) network?

Got it.

It was a DNS problem where public ones could not be used under our corporate firewall. I set it to our internal and it's working now.

Well, I was somewhat right I guess.

I'm surprised you don't get DNS from DHCP.  IIRC, windows allows you to set it to pull from DHCP but if it gets no reponse, it can use an alternate profile of IP settings.  That's XP, and I haven't used it much in years so maybe I'm wrong.
