Openmptcprouter: [FeatureRequest] TTL Mod

[juristoeckli]

Expected Behavior

TTL increase on Wan

Current Behavior

Please add the function to set an ttl offset. Some Mobile network providers use the TTL value to block or charge different for hotspot Data. if we can set the ttl to one higher tan normal it will look like data from the phone to the network provider.

I added in develop branch the "sysctl net.ipv4.ip_default_ttl" setting.
I will add later change of TTL by interface.
