One of them is to parse packet trying to detect inner encapsulation

Current solution: The solution was UNEXPECTEDLY SIMPLE.

We force DF flag on tunnels with preconfigured hop limit,

that is ALL. :-) Well, it does not remove the problem completely,

Yes, it is not good if there exists a router in the loop,

which does not force DF, even when encapsulating packets have DF set.
