Our existing ADSL/Broadband service which originally came supplied as standard with 16 static IP addresses is being "regraded" to a newer FTTC service.

We operate from a single site and over the years have only ever used two of the available static IP addresses - one for our internet and VPN traffic and the other for our GW server primary MX record. We are licensed for the Open Workgroup Suite but have never got in to using Filr or Vibe.

The new FTTC service only comes as standard with 1 static IP address.

Just trying to figure out if there are any gotchas or headaches that we might experience further down the line by not having additional IP addresses available or perhaps I'm overthinking this and worrying about nothing?

Any thoughts or suggestions gratefully received.
