Fix Information

You can now configure TTL Options (set, preserve, proxy, decrement) on the ipother profile. This is available on both IPV4 and IPV6. Specifies the outgoing packet's IP Header TTL mode. The default is Decrement. The available settings are: -- Proxy: Sets the outgoing IP Header TTL value to 255/64 for IPv4/IPv6 respectively. -- Preserve: Sets the outgoing IP Header TTL value to be same as the incoming IP Header TTL value. -- Decrement: Sets the outgoing IP Header TTL value to be one less than the incoming TTL value. -- Set: Sets the outgoing IP Header TTL value to a specific value(as specified by ip-ttl-v[4|6]).
