Currently, if one doesn't have an IGD-enabled gateway, Diplonat will fail with "Failed to find gateway".

I want to use Diplonat for ACME on Hammerhead, which is a Kimsufi server with a public IP and fully opened ports. I won't use the IGD part.

Since I plan on implementing ACME, Diplonat will soon be constituted of four modules:

Consul (mandatory; it feeds the other modules)
IGD (optional; negociates ports' mapping declared in Consul service tags)
Firewall (optional; opens the above ports in iptables)
ACME (optional; it generates TLS certificates for domain names declared in Consul service tags).

My plan is to modify the environment variables names as follows:

New DIPLONAT_IGD_ENABLE (bool), defaulting to false
New DIPLONAT_FIREWALL_ENABLE (bool), defaulting to false
DIPLONAT_EXPIRATION_TIME -> DIPLONAT_IGD_EXPIRATION_TIME
DIPLONAT_REFRESH_TIME -> DIPLONAT_IGD_REFRESH_TIME & DIPLONAT_FIREWALL_REFRESH_TIME (these two have no reason to be correlated, and the naming scheme will be cleaner this way).
DIPLONAT_PRIVATE_IP -> DIPLONAT_IGD_PRIVATE_IP
Add a bunch of DIPLONAT_ACME_* stuff as needed.
