Hi guys,

My office had just moved from one premises to another and we had just gotten our Internet service up and running. Since our old office had ADSL, our new location has ADSL2+ so I had to replace the Router (CISCO Series 800A) we had since it was not very stable running on ADSL2+ to a NetGear DG834G which is working fine.

Since the change though, our Microsoft Exchange and Windows SBS VPN hasn't been working properly. Basically, our office down south can't seem to establish a VPN connection and Microsoft Exchange hasn't been forwarding email to peoples phones.

I'm guessing since these things stop working on Friday afternoon (which was when I had replaced the router), there's a setting within the router I've overlooked. Any ideas what this could be?
 
Replacing a decent cisco with a crappy netgear, bad move for a start :(

Anyway, sounds like you just havent configured port forwarding on the new router
 
Might not be the best in the world, but it's stable. Quite frankly, a 6 year old router only capable of handling old ADSL doesn't quite cut it :P

Ahh, port forwarding, so that's what it is. Where abouts on my domain server (Windows 2003 SBS) would I find which ports I need to forward?
 
Well it really depends what services you're using which ports you need to forward, congratulations on not checking the config on the old router before you replaced it...
 
Yeah, my apologise, I'm far too new to this :( The CISCO Model 800A doesn't have some easy to use Web Configuration (that I know of)

Microsoft Exchange is just used for our Domain emails, some Outlook Web Access for people to lookup from home and pushing the domain emails to our managers Nokia E71's.

No it doesn't, it has the standard Cisco CLI, but it's a bit late unless you can dig out the config and look at it now...

Well you'll need 80 and 443 forwarded for OWA, if it's getting SMTP email rather than collecting POP you'll need 25, and whatever VPN ports depending on the protocol used.
 
Cheers for pointing me in the right direction. Got the Pop3 stuff working, domain emails working, VPN working, not quite got the Outlook Web Access working on my managers Nokia E71 yet, but I'll dig into that a little further later on in the day.

I had to add our exchange server IP address into the default DMZ server in WAN setup on our Netgear router

You might wan't to re-visit that and use port forwarding instead as you have effectively put the entire server directly on the net without any firewall.
 
If OWA and EAS arent working, you havent forwarded 443 (or 80 if you're daft enough to run them on HTTP rather than HTTPS)

Netgears are anything but stable, especially in a corporate environent - I'd replace it with a proper router, a Cisco 877

My view is the best implementation is to allow HTTP and have IIS redirect to HTTPS, if only because it saves users having to work out they need to specify https in the url...
