Corporate Intranet doesnt work through VPN

[armyofda12mnkey]

We have some trouble here goign onto VPN with our verizon wireless connection.

Our Employees cannot access the corporate intranet which you usually goto by typing...
http://intranet (our production intranet site on machineA)
or
even http://ip.add.r.ess doesnt work

However these work:
http://intranet:90
or
http://ip.add.r.ess:90 (our development intranet site on machineA)

The hosts file on the laptop machines are mapped from the IP to the word intranet like so...
ip.add.r.ess intranet
...so it should work correct?

When going to http://intranet, they get a error message
Error 503 service unavailable from 66.174.92.163
which seems to be an error message from Verizons network saying they dont have anything mapped on their network to the word intranet.

I tried everything that me as a simple web developer could think of: host file, ipconfig /flushdns, looking at Ethereal logs for the VPN network adapter(although I am not a network guy I can barely understand the logs other than the its communicating with our DNS and the DNS never tells it intranet=ip.add.r.ess).
Out network admin is at training for next couple weeks, so not sure if its a Firewall or VPN issue. But i would like to do a favor for him and debug it a little since he is swamped enough as is.

Any ideas guys?
Thanks in advance.
Sorry for the length post,
its my 1st.

From my experience with Intranet Accessed VPN's I add the http(s)://intranet: (PORT) into the Trusted sites. From my experience you MUST use the port in the address. Your firewall must have the port exposed to intranet connectivity.

the :90 at the end of the address specifies the port that the connection goes through, My guess is that when they just type in the address with out the :90, it tries to use a default port setting, and this port is being blocked by your firewall. so you either just have to have type the :90, (which isn't much of a porblem i think), figure out which port is the default and punch a hole in your firewall for it, or change the default port for the internet browser that you are using, (could cause problems with regular surfing). Another thing that you can do is make the browser automatically route to the :90 address when they type it in without it. (i.e. I can make my browser go to google.com when someone types yahoo.com, by changing how my browser handles that google.com address. (I used to know how to do this, forgot it now).

Hope that helps!

I'll let network admin know he probably has to punch a hole through firewall. seems funky though that when connected though VPN, you can access other external sites which are of course on port 80,yet the one which i would assume would definately be the easiest to visit is the one on office network I am connected to through VPN. Cause i assume even though i am conncted really through anothter connection, that everything goes through the VPN as if i am at the office. So if i am went literally to the office and http://intranet works fine, would it still have the same issue as going through VPN?


Is there a reason why port 80 specifically on my network would be blocked/not punched through the firewall when going through VPN, yet port 80 works fine for accessing external sites?

The web browser's use port 80 by default, so when you type http://intranet which you have the host file configured on the each clients to point to the correct IP address right? Then it will go to port 80, which is not being sevice by your server, instead it's servicing on port 90 as you describe..so change that on the server and open up port 80 or tell your users to do :90 after the ip or host name.

well the web server is servicing on port 80 AND 90. 90 is the development testing website, 80 is production website.
80 and 90 both work fine when you are in the office.

90 works on VPN,
80 doesnt on VPN

so i cant simple change 90 to 80 on the web server.
80 is already running, its just not being seen by VPN.
http://intranet works in office but not on VPN
http://intranet:90 works in office and also works on VPN.
Need to get 80 working on VPN, and i cant change 80 so some other port, imagine the internet if we had to do that all the time
