I'm interested in setting up an IPSec tunnel between a Cisco 861 router, and an ASA.<br />
<br />
The reason for this, is that the site to site link for my LAN traffic is very slow... I want to try and balance some of this LAN traffic over the tunnel, and hopefully improve quality of service.<br />
<br />
First and foremost, is it even possible for the router to load balance between the two gateways? &nbsp;Is it possible for me to set the route with a very similar metric, so that connections get fired through each pipe more or less evenly?<br />
<br />
Secondly, I have a config that I'm pretty sure I can use (googled it and found the cisco documentation). &nbsp;Once I know whether it is possible or not, I would be potentially inclined to get some assistance, should the config not work.<br />
<br />
Edit:<br />
<br />
There are currently two connections at the off-site location. &nbsp;One ADSL connection (currently just running as a default route for anything not directed to the 10.0.0.0/8 subnet), and one site-to-site connection for anything directed to the 10.0.0.0 subnet.

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Internet Protocol Security (IPsec) is a protocol suite for secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPsec includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session. IPsec can be used in protecting data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). IPsec is an end-to-end security scheme operating in the Internet Layer of the Internet Protocol Suite.
