Public IP address not always visable online
In a remote location in the UK, adsl broadband not available.
Setup: Wireless aerial in our customers office which connects wirelessly to the customers broadband supplier’s transmitter, Cisco broadband router is plugged into the aerial with static private IP address of 10.222.128.2, the broadband company have assigned a static public IP address which routes to the cisco router e.g. 87.202.87.78
Ok I've been connected remotely to our customers server which is plugged into the cisco router all day, connection hasn't dropped once. So the broadband seems fine. But..... The connection to the cisco router remotely at http://87.202.87.78:7454 is intermittent, sometimes I just can't connect to it, just not seen on the internet, when this doesn't work https://mail.mycompanyweb.co.uk/exchange also doesn't work, which would make sense as https://mail.mycompanyweb.co.uk points to 87.202.87.78.
Anyone got any suggestions as to whats going on, it seems like a routing problem or issue with the broadband supplier?

I'd guess its a problem with the wireless link if it's intermittent.
Set up a couple of pings from the server to test the wireless link and the connection to your router... something simple like:
ping 10.222.222.254 -t > c:\pinggateway.txt
ping 192.168.0.254 -t > c:\pingrouter.txt
This will tell you if you're losing connection to the ISP or to your local router, just look at the text files on the C: drive.

@ I don't get a ping from 87.202.87.78 if its working or not.
@craigbeck Will try your suggestions, the wireless link connection doesn't drop though, as I was connected remotely to the server all day today.

@craigbeck I successfuly ran ping 10.222.222.254 -t > c:\pinggateway.txt & ping 192.168.0.254 -t > c:\pingrouter.txt for 8hrs and have looked through the logs and their was no timeouts.
Don't think the cisco router has an option to enable to respond to ping on the internet.

So RDP works flawlessly, even when Outlook Web Access doesn't??

I am connected to the server using logmein all day. I guess thats a web based remote utility. Ok i'll setup rdp to the server and connect remotely using rdp to 87.202.87.78??
You could try that. Is there anything in the Event Log on the server which indicates any Exchange or IIS services failing, etc?

Ok now connected with rdp. No logs in event viewer over the last few days.
