tinc enforces it. It will reject any oversized packet with DF set. > Could it be possible that Tinc did its PMTU discovery magic in that moment? Yes.

It will also show oversized packets being rejected. _______________________________________________ tinc mailing list [email protected] http://www.tinc-vpn.org/cgi-bin/mailman/listinfo/tinc
