Hi
I have been testing from inside the LAN and getting someone ocasionally from
outside the LAN, (I know its not ideal but loopback works on 3com
officeconnect dsl)

I can connect to OWA, when try to Connect to the Server this is when it fails

Yes from LAN get https://SBS_external_private_IP/remote using there ip or
mail.client.com host name can login but fail on Connect to Server

From lan https://127.0.0.1/remote can login and Connect to Server

4125 will show as closed, it is opened on SBS dynamically by RWW, and then
only to the requesting IP. The router, if forwarding 4125 to the server is
forwarding to a port which GRC will _never_ see as 'open'.

The request from inside the LAN to the pulic name is also _most likely_ to
fail due to a limitation of most routers in that they do not process
'loopback' connections (ie. a connection from their LAN side to the WAN IP
and then back to the LAN.

SO, lets set ground rules for everyone else as well.

4125 IS NOT REQUIRED BY RWW, and Dave is getting a failure connecting to RWW
(ie. https://mail.whatever/remote). The _only_ port used for this connection
is 443. This connection should display a web page, but isn't.

Dave, you are (hopefully) testing from _outside_ the router (ie. another ISP
connection), right?

From the LAN, do you get anything when browsing
https://SBS_external_private_IP/remote ?

Dave,

Goto https://www.grc.com/x/ne.dll?bh0bkyd2 click on the "Proceed" button
type the port you want to check and click on the 'User Specified Custom
Port
Probe'. Try both 3389 and 4125

See what the result is. Since you can access the remote internally, the
configuration is correct. If there was a problem with RWW you wouldn't be
able to access it internally either. Something is preventing the
external
connections. What is the exact error number you get in Internet
Explorer?

Hi Costas,

It has a hardware sonicwall firewall. The user has lost the password so
before resetting this I brought in 3com officeconnect. did all the
usual
setup of this configured firewall ports as below. Wont connect. I
turned
off
firewall and tryed with no luck.

Is there any way of testing connections to port 4125

Maybe it needs a RWW reinstall?

This is most probably a firewall issue. I would start by disabling
the
firewall on the router and see if you can access the remote. If not,
then
re-enable the firewall (with the forwarded ports as you have them now)
and
move to the server. If you have two NICs on the server then go to
Routing
and Remote Access and check the basic firewall to make sure that the
4125
port is open. I know you said that you run CEICW but these checks are
for
the 'just in case' scenario.

Dave,

Is this a Standard Edition? (No ISA)? R2? Is SP2 installed?

You don't use the 127.0.0.1 IP address to access the server over

Hi There,
I can connect to https://127.0.0.1/remote but cannot connect
over

RWW
