Network Shares via VPN OK one way, rejected the other way

[MrOrange]

Hi There,

I am hoping that someone can help me with this, as i have no more hair left
to tear out.
Allow me to explain.
We have two sites linked via a vpn tunnel, two different domains, one site
in the UK and one site in Ireland.

Both sites can ping each others routers and main servers.
RDP works either way

The problem arises when trying to open a network share located in the
Ireland site.

For example, sitting on a machine in the uk, open a run command and enter
\\192.168.16.2 - after about 30 seconds to a minute i get a error – The
network path was not found.

If i enter a hidden share ie \\192.168.16.2\c$ after about 30 seconds a
password authentication request box appears asking for credentials.
I enter the domain administrator user name and password (which i know are
correct as i have performed a rdp to the same machine) and wait – after about
30 seconds, the authentication requestor is back again.

I have also tried various combinations of the username ie
(e-mail address removed) mydomain\administrator – etc All result in a
brief pause then the requestor is back.

Now going from the other direction is a different matter – if i RDP onto the
server in Ireland, then open the Run command and put in a ip for a server in
the uk – i get another password authentication request, i enter administrator
and its domain password, after a brief moment, i am presented with the shares
on that server.

hmm yeh - it got me thinking, i created a share on the ireland server with
full access permissions for everyone, tried to access it on the uk server,
failed (expected) - then tried the same path on the actual ireland server,
this should work - it didnt...it seems to be a routing issue of sorts, i have
a headache at present so im going to step through this carefully, but i think
im on to something..

as you say that both cards must not share the same subnet, so if i say, set
the external facing nic (ie the one plugged into the router) from
192.168.16.2 to 192.168.18.2 and leave the internal (the one plugged into the
local switch) nic as 192.168.16.1 - it should work?

Vpn is a managed service....

Hi There,

I am hoping that someone can help me with this, as i have no more hair
left
to tear out.
Allow me to explain.
We have two sites linked via a vpn tunnel, two different domains, one
site
in the UK and one site in Ireland.

Both sites can ping each others routers and main servers.
RDP works either way

The problem arises when trying to open a network share located in the
Ireland site.

For example, sitting on a machine in the uk, open a run command and
enter
\\192.168.16.2 - after about 30 seconds to a minute i get a error – The
network path was not found.

If i enter a hidden share ie \\192.168.16.2\c$ after about 30 seconds
a
password authentication request box appears asking for credentials.
I enter the domain administrator user name and password (which i know
are
correct as i have performed a rdp to the same machine) and wait – after
about
30 seconds, the authentication requestor is back again.

I have also tried various combinations of the username ie
(e-mail address removed) mydomain\administrator – etc All result in
a
brief pause then the requestor is back.

Now going from the other direction is a different matter – if i RDP
onto
the
server in Ireland, then open the Run command and put in a ip for a
server
in
the uk – i get another password authentication request, i enter
administrator
and its domain password, after a brief moment, i am presented with the
shares
on that server.

Ok been twiddling around...

On the Ireland server (oserver.yourdomain.local) i have now one nic facing
the router of :

192.168.15.2
255.255.255.0
192.168.15.254 (router)

and the other nic facing the internal network:

192.168.16.1
255.255.255.0


on the same server, i can ping both address's (expected) but when trying to
open them as a network share, there's problems,

ie clicking Start/Run then entering :


\\192.168.16.1

....results in the local network share opening - as expected

clicking Start/run then entering:

\\192.168.15.2

....results in a pause of about 30 seconds then a message informing me it
cannot locate the network share.

This to me - baring in mind i know very little on routing tables etc, sounds
like there is no link between the nic's ie segregated. I am then assuming
its simply a case of an addition to the ireland's routing table?

Another thing to bare in mind, which might help someone identify the
problem, on the Ireland server, i can open a share located on a server in
Warrington (there's a vpn tunnel) by entering its full domain eg

Start \ Run

\\dbase.mydomain.lan

This opens the share located on the dbase server in Warrington, which is fine.

From the other side ie the Warrington server, i enter:

Start \ Run

\\oserver.yourdomain.local

After a short pause - the no network share available msg appears. (tried
also via ip)


Please help! - i have spent the day bashing my head on this and got pretty
much no where and feel rather disheartened by the whole thing - it feels like
its just out of my reach...tip of my tongue, just around the corner, etc,
etc... Can someone PLEASE help ?

Thanks in advance!!!

hmm yeh - it got me thinking, i created a share on the ireland server with
full access permissions for everyone, tried to access it on the uk server,
failed (expected) - then tried the same path on the actual ireland server,
this should work - it didnt...it seems to be a routing issue of sorts, i have
a headache at present so im going to step through this carefully, but i think
im on to something..

as you say that both cards must not share the same subnet, so if i say, set
the external facing nic (ie the one plugged into the router) from
192.168.16.2 to 192.168.18.2 and leave the internal (the one plugged into the
local switch) nic as 192.168.16.1 - it should work?

Vpn is a managed service....


Thanks again for taking the time to look at this

We have some issue with OSERVER.IRELAND.LOCAL configuration. Is
OSERVER.IRELAND.LOCAL DC? If yes, you may have a name resolution and routing
issue. It is not recommended to run a DC on a multihomed computers.

Both IP addresses should not be in the same ip range.

Which VPN service are you using?

Hi There,

I am hoping that someone can help me with this, as i have no more hair
left
to tear out.
Allow me to explain.
We have two sites linked via a vpn tunnel, two different domains, one
site
in the UK and one site in Ireland.

Both sites can ping each others routers and main servers.
RDP works either way

The problem arises when trying to open a network share located in the
Ireland site.

For example, sitting on a machine in the uk, open a run command and
enter
\\192.168.16.2 - after about 30 seconds to a minute i get a error – The
network path was not found.

If i enter a hidden share ie \\192.168.16.2\c$ after about 30 seconds
a
password authentication request box appears asking for credentials.
I enter the domain administrator user name and password (which i know
are
correct as i have performed a rdp to the same machine) and wait – after
about
30 seconds, the authentication requestor is back again.

I have also tried various combinations of the username ie
(e-mail address removed) mydomain\administrator – etc All result in
a
brief pause then the requestor is back.

Now going from the other direction is a different matter – if i RDP
onto
the
server in Ireland, then open the Run command and put in a ip for a
server
in
the uk – i get another password authentication request, i enter
administrator
and its domain password, after a brief moment, i am presented with the
shares
on that server.

 

[MrOrange]

has anyone got any suggestions?

Ok been twiddling around...

On the Ireland server (oserver.yourdomain.local) i have now one nic facing
the router of :

192.168.15.2
255.255.255.0
192.168.15.254 (router)

and the other nic facing the internal network:

192.168.16.1
255.255.255.0


on the same server, i can ping both address's (expected) but when trying to
open them as a network share, there's problems,

ie clicking Start/Run then entering :


\\192.168.16.1

...results in the local network share opening - as expected

clicking Start/run then entering:

\\192.168.15.2

...results in a pause of about 30 seconds then a message informing me it
cannot locate the network share.

This to me - baring in mind i know very little on routing tables etc, sounds
like there is no link between the nic's ie segregated. I am then assuming
its simply a case of an addition to the ireland's routing table?

Another thing to bare in mind, which might help someone identify the
problem, on the Ireland server, i can open a share located on a server in
Warrington (there's a vpn tunnel) by entering its full domain eg

Start \ Run

\\dbase.mydomain.lan

This opens the share located on the dbase server in Warrington, which is fine.

From the other side ie the Warrington server, i enter:

Start \ Run

\\oserver.yourdomain.local

After a short pause - the no network share available msg appears. (tried
also via ip)


Please help! - i have spent the day bashing my head on this and got pretty
much no where and feel rather disheartened by the whole thing - it feels like
its just out of my reach...tip of my tongue, just around the corner, etc,
etc... Can someone PLEASE help ?

Thanks in advance!!!

hmm yeh - it got me thinking, i created a share on the ireland server with
full access permissions for everyone, tried to access it on the uk server,
failed (expected) - then tried the same path on the actual ireland server,
this should work - it didnt...it seems to be a routing issue of sorts, i have
a headache at present so im going to step through this carefully, but i think
im on to something..

as you say that both cards must not share the same subnet, so if i say, set
the external facing nic (ie the one plugged into the router) from
192.168.16.2 to 192.168.18.2 and leave the internal (the one plugged into the
local switch) nic as 192.168.16.1 - it should work?

Vpn is a managed service....


Thanks again for taking the time to look at this

We have some issue with OSERVER.IRELAND.LOCAL configuration. Is
OSERVER.IRELAND.LOCAL DC? If yes, you may have a name resolution and routing
issue. It is not recommended to run a DC on a multihomed computers.

Both IP addresses should not be in the same ip range.

Which VPN service are you using?
