Re: Connecting Remote ofice with High Latency VSAT



Hi Chris,

I think PC's can ping from site a to b.

I'll double check this and verify.

If they can (i am sure they can), what else could be causing this problem ??

Its almost midnight here so I'll follow up wih you in the morning.

Thanks for your help.

Dave

(or keyboard to keyboard?)

If site A is 192.x.x.x. and site B is 172.x.x.x

Can a PC on Site A ping a 172.x.x.x address?
Can a PC on Site B ping a 192.x.x.x address?

If they cannot - the sites are not actually linked (WAN) but instead both
access the internet. If all servers are at Site A, you will need to rely on
Internet based communications (OWA, RPC over HTTPS, etc)

Chris,

the 2 sites communicate through the VSAT connections.

Site A uses a Cable/DSL connection (provided by a local telco) to gain
access to the internet. Everyone at site A uses this as the gateway to the
internet.

If a client from site B wants to access the internet, the request would
got
through to site A and the out through site A's default gateway

To answer your question, both sites can ping each other.

Dave.

P.S i can send you a very rough drawing of the layout if it helps

David,

The part I am missing still is connectivity between the two. It sounds
like
they communicate across the Internet (FTP) - or do you have a site to
site
VPN configured somehow.

Mmeaning - Can site B ping a site A IP address and vice-versa?

Chris,

Thanks for the reply. I can't remember the ranges off the top of
myhead, I
can provide them later if necessary. From memory, Site B has a range of
172.xxx.xxx.xxx and Site A uses a 192.xxx.xxx.xxx.

the connection is through a Satellite ISP but Private IPS have been
issued
to both routers. PC's on both sides can communicate and tests (FTP
transfers)
have been sucessful.

Site B uses the same DNS as everyone at the main office (Site A).

As I said, i can get you all the ipconfig info later if needed.

Let me know.

Does any of this help ??

Dave

Give some numbers...

What are the internal IP ranges on both sides of this network.

Is this a private connection, or a satellite internet connection?
(just
checking)

Whats the DNS servers in play and ipconfig/all on either side's
clients?

Chris

Hi Guys,

I've been asked to help out with a issue and I need a little
assistance.

This reminds me of one of those "Scenario" questions on the MCSE
exams
so
I'll try my best to keep it simple. So here we go.

The "Acme Trading Co" has a Windows 2003 AD infrastructure with
multiple
users on 2 subnets. The use Exchange 2003 for messageing and hav Web
access
enabled. All of the exisitng users reside ins the same office
building
and
use a traditional 10/100/1000 mbps cabled network.

All users are given access to the internet through ISA server. The
gateway
is a high speed Cable connection which connects them to the public
internet.

(now here's the fun bit)

Recently they have opened a storage facilty which has approximately
20
users
(Site B). This office is connected to the head office (Site A) via a
VSAT
connection. The bandwidth is high (approx 512/512 kbps) and the
latency
is
approx 1200ms.

Users are given private IP and the router has a static route to the
head
office (site b). Users are able to browse the internet through the
circuit
but they are not able to log on to the exchange server. They get
asked
to
authenticate but nothing happens once they have entered their user
name
and
password.

On the OWA side, they can not gain access to the server if the use a
private
IP address for the server, but, if thy "take he long way round" and
use
a
public name/address they can get on. Granted, its a bit slow but i
works.

Has anyone go any ideas ?? Are here TTL limits in place that could
cause
this or am i missing something ???

Any help would be greatly appreciated.

Thanks

Dave
