IPSEC Tunnel causing high internet traffic!!!!
Posted on 2009-07-10
I have the following setup
Head office is the domain controller with a 4mb ADSL LINE, a billion b7402gx establishes the adsl connection.
Branch office has two workstations that is connected to another billion b7402gx with adsl. Two connect the two sites the billion router establishes a permanent ipsec tunnel between head office and branch office. the reason for the tunnel is
: Head office is antivirus server with trend micro server and branches need to be in sync
: The branch logs into the Head office dc
: Branch workstations use Head office ip as primary dns to resolve domain
: Branch uses RDP to use accounting software at head office
WHENEVER THIS TUNNEL IS ESTABLISHED THE USAGE OF INTERNET BANDWIDTH INCREASES BY AT LEAST 400MB PER DAY ON BOTH THE HEAD OFFICE AND BRANCH??? AUTO UPDATES TURNED OFF, ALL TORRENTS AND KNOWN SITES BLOCKED, ACCOUNTING SOFTWARE NOT USED YET SO NO RDP SESSIONS CAUSING THIS EITHER, WHAT COULD THIS BE?
