Subject: Decrement TTL of incoming packets.
X-Git-Tag: release-1.0.17~19
X-Git-Url: https://tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=0233b1d710222cb09be0cbd08c1297e3ece38a9f;hp=0233b1d710222cb09be0cbd08c1297e3ece38a9f

Decrement TTL of incoming packets.

Tinc will now, by default, decrement the TTL field of incoming IPv4 and IPv6
packets, before forwarding them to the virtual network device or to another
node. Packets with a TTL value of zero will be dropped, and an ICMP Time
Exceeded message will be sent back.

This behaviour can be disabled using the DecrementTTL option.
