Hi<br />
I have a 20MB line to the Internet in work in Ireland and we have an office on the East Coast of USA with a T1 1.5MB Line. &nbsp;We have a Site to Site VPN setup between sites which on the face of it seems slow The hardware involved is a sonciwall pro 3060 in ireland and a Cisco PIX in USA. &nbsp;I realise that the VPN has overheads etc but i was wondering if there is any calculation that i can preform to prove that the bottleneck is the 1.5MB line... &nbsp;Ive done testing between sites and have seen that whn i decrease the MTU on both side to 1430 i am gettin improvements but it is still taking me 28 minutes to move a 102 MB File from one site to another over the VPN. &nbsp;Any Help is greatly appreciated<br />
<br />
thanks<br />

Speed of Site to Site VPN between Ireland and USA

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.
