Frequently Asked Questions (FAQ)

Does it work from behind a NAT or firewall?

AICCU works from behind a NAT setup it is even capable of passing most firewalls. Do note though that AICCU is only the tool for setting up a tunnel. The tunneling protocol itself must be able to cross a NAT too. In general AYIYA will work in most situations, unless it gets firewalled.

Protocol	Notes
AYIYA	Works over firewalls and NAT's
Protocol-41 / Heartbeat	Requires the use of a public IP address or when behind a NAT requires the configure of the NAT box to make the host where the tunnel is really terminated, the 'DMZ' host.

To be able to use AICCU, one should also be able to access the TIC service.
