Victor Kareh 167a57e739 firewall: Allow overriding the TTL
In instances where a cluster pod in a local VM needs to access a server
that is sshuttle'd from the host, since the packets arriving at the host
already made a hop, their TTL is 63 and so get ignored by sshuttle.
Allowing an override of the firewall TTL rule allows the packets to go
through.
