London                          Firewall                         Firewall                      Aberdeen
192.168.1.1                   192.168.1.10                 192.168.10                  192.168.0.2
                                                           VPN
                                                                                                           Mail Server



I have the following set up for certain reasons and it cant change.

How do i stop desktop users from London obtain there mail  via Outlook?
I have blocked port 80 on the London side firwall. THis dosnt work as the VPNs route the mail internally.
I cant uninstall Oultlook not an option.

How do i stop them RX mail.

The reason for this the users in london use citrix and collect there mail from citrix.

As all users some have fiddled and found the route via the vpn to collect mail with out citrix. Causing my Bandwidth loss.

Thanks

Dear ellandrd,
Block the Mail server access when they try to come in via VPN. Port 80 is for Outlook web access. This is not used when you use outlook. Better block whole IP.

Cheers!

On your (Aberdeen) firewall create a rule that blocks all traffic on all ports from the 192.168.1.0 subnet to your mail server's IP.  Depending on what your Firewalls are you should be able to select VPN as the interface instead of WAN.
