# this custom script in addition to MODE=nfqws runs desync to all QUIC initial packets, without ipset/hostlist filtering
# and also sends special fake on the first outgoing packet with short header and udp.length>600

# need to add to config : NFQWS_OPT_DESYNC_QUIC_SHORT_HEADER="--dpi-desync=fake --dpi-desync-any-protocol --dpi-desync-fake-unknown-udp=/opt/zapret/files/fake/quic_short_header.bin --dpi-desync-cutoff=n2"
# NOTE : do not use TTL fooling. chromium QUIC engine breaks sessions if TTL expired in transit received
# this hack was first intended for TSPU but it appeared that it's overkill
