I am designing a solution for a customer that needs to connect two small office locations.
Ideally, I would suggest they purchased a Frame Relay connection between each office, but their monthly budget may not allow this.
So, I am going to propose a site to site VPN solution. Both locations have 6Mbps DSL down and about 512Kbps up. The site to site connection would be up at all times.
The type of traffic that would go across the pipe is transactional information. Nothing too bandwidth intensive.
I plan on utilizing two 800 series routers behind an existing DSL modem that will set up as a pass through so that the public IP information will be assigned to the router.
What are some issues to be aware of with this setup. Can routing protocols (OSPF or EIGRP) be run across the IPsec VPN tunnel? Is the configuration straitforward?
Thank you in advance for any advice.
