All you need is One IP. You will be setting up Multiple Tunnels though. I believe that with the base license you can have up to 10 tunnels, and with the Security Plus 25.<br />
<br />
here a tutorial on how to start the first one.<br />

We want to set up our 5505 to handle multiple S2S VPN's with remote 5505's. Couple of questions:<br />
<br />
Do we need multiple IP's on the outside interface or just a different policy for each?<br />
Are there any caveats to this, performance concerns, best practices?<br />
<br />
Thank you.

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
