VPN site to site between Cisco ASA 5520 and PIX 515 E with dynamic IP

Dear All,

    I have two sites, main branch site and remote site, in the remote site I have internet access using microwave device ( Mada DX-250 ), i need to create a vpn site to site using the PIX 515 e in my remote site connected to mada router which gives dynamic ip address, can someone help me with the steps, i have tried client to vpn and its fine but I need site to site since I have 5 machines in the remote site that has to be connected always.

please note that in the mainsite I do have static IP, the issue only in remote site that has dymanic ip.

You really need static IP addressing in both sites.  For the site with Dynamic IP, you can use DynDNS to create fixed IP for yourself and DynDNs will work out the connection. You can VPN in through this, so I think Site to Site will also work.

How frequently does your IP address change. My home IP address changes once every one or two years. So I just treat it as static and change the VPN settings when needed.

Take a look here:


Even though this document describes ASA to Router with dynamic IP, Router and PIX commands a pretty the same.

Let me know if you need more help

In your case I would set the ASA with the fixed IP up as an EazyVPN server, and the PIX with the dynamic IP up as an EazYVPN client
