All customers will be supplied one fixed IP address by Sharedband. Traffic will appear to the Internet to be from Sharedband supplied IP address(es) rather than your individual Broadband connections. If you are running any non-TCP or UDP based VPN (IPSec, PPTP, GRE, L2TP) you will need a dedicated IP address per VPN. Sharedband allows port forwarding, so web servers, mail servers etc. can be hosted behind Sharedband.
Sharedband supply all IP addresses in NAT mode as standard. Customers ordering 4, 8 or 16 IP addresses can opt to have them configured in routed mode, where the LAN addresses of devices are the same as the external IP address. This is necessary for some IP address specific services, such as IPSec ESP VPNs.
