VPN with ASA and routers with ADSL dynamic IPs

Hi ...

I have the following scenario:

One ASA5510 firewall in the Central Office, this is the headquarters of the company, this ASA has configured just two interfaces; inside and outside.

We have a 5Mbps Internet connection in outside, the inside is an small network with some class C subnets.

We are installing some small remote office with ADSL Internet connections.  These offices has routers 877 with ADSL connections with DHCP IP address asignation.

We need to connect with VPN these new remote sites with the Central Office.

What is the best way to connect with VPN these sites ?

Re: VPN with ASA and routers with ADSL dynamic IPs

Hi,

I see two options.

1. IPsec site-to-site tunnels

2. Easy VPN

From personal experience, I recommend Site-to-Site IPsec tunnels between the main site and the branches.

Here's a configuration example:
