Can we Configure a Site-to-Site with Only One Public IP Adress?

[BytesSolutions]

Do we really need public IP addresses at all sites into site-to-site configurations or we can only have public IP address at the UT server site?

In case we can make this configuration using just one public IP address at the server site, do we need at least to configure a dynamic DNS service at other sites?

My question is related to connecting Client Sites using lower cost aDSL circuitos with dynamic IP addresses.

Thank you in advance for your clarifications!

Sure.

You'll likely have frequent outages as the dynamic IPs change, but once your DNS is updated and all the caches flush it should reconnect.

Okay!!

So, in that scenario you definitelly recommend at least using dynamic DNS services (such as DynDNS) for remote sites to reduce the outages?

I've been using this service for a single site which requires remote clients to connect and have not had any issue up to now.

Well, you have to use some DNS service unless you want to reconfigure your settings every time an IP changes.

Some ISPs "dynamic IPs" only change once a year, some all the time. It really depends.
Either way, just be prepared for outages which may be fine depending on what you are using it for.
