Make mode -9 the default, instead of -5
Browse files Browse the repository at this point in the history
Auto-ttl gives many false positives in TTL detection, which breaks non-blocked websites.
Use the combination of wrong-seq and wrong-chksum and hope to the best.
Also block QUIC to workaround possible throttling, as right now it is not dissected.
