Scenario: RUnning exchange 2000 on windows 2000 servers.
Clients running Office XP (outlook 2002).


I have a laptop, where outlook can run offline - and was hoping to use my mobile phone GPRS & bluetooth to vpn in occasionally if away from either a WiFi point or a wired lan. Unfortunatly my GPRS provider (orange, in the UK blocks port 1723, so no vpn.

In outlook..tools...email accounts...under the exchange connection, more settings..connection...there is an option to connect to exchange server when working offline. Can I specify a dial up conection (to the internet) and then have it connect to the server? If so, what ports / protocol does it you?

Many thanks.

Why not just connect to the internet and use OWA

I could do that - however my laptop is normally online and has outlook installed (with everything that that implies).

I then want to compose emails offline and then either send them via this dial up connection, or have them automatically sent the next time it connects to my internal network.

For instance, one place where I visit occasionally has no telephone, and no mobile phone reception. I would like to be able to compose emails there, whilst working - then at the end of the day lug my laptop and phone up the hill to get some reception and send it all off.

OWA might get a bit expensive when paying by the MB...

cAN THEY OPEN UP PORT 1723 FOR YOU?

That is a port for IPSEC traffic, how about creating a PPTP client?

My CEO travels all over the world, and sometimes the IPSEC VPN Connection doesn't work so He'll use a PPTP instead.

It isn't as secure, but it doesn't use as many ports that can be blocked.

If you can get a dialup to the internet you can then conenct to the VPN and try it that way. It will be really slow.

I would also suggest a manual entry in your host file so it can resolve you exchanges servers IP address.

 
Ohhh... Wait.. I was Incorrect I had it backwards

PPTP connections use
47 ip
1723 tcp

IPSEC uses
50 ip
51 ip
500 udp

My Firewall (WatchGuard FB 700) uses both IPSEC and PPTP.
I use the MUVPN Program that comes with the Firewall, and it uses IPSEC. If that has connection problems, my users then use the VPN connection that comes With Microsoft (upder Network Connections) and that uses PPTP.

I'd check what protocols your Firewall can use, and enable it for both, to make sure that one or the other connection will work.

You could also have L2TP (I've heard of it, nut have no experience with any devices that use it. L2TP uses ports

500 UDP
1701 UDP
