(adsbygoogle = window.adsbygoogle || []).push({}); So I'm running CFG patches for a while but never had the time to host public.
I'm never the host, my internet connection is not that good but I have Force Host
in my patch but I don't know in which case this helps me.

I have Net Tools too. But when I activate my UDP Flooder, I just don't match a game.

Anyone who knows a method?

First of all u NEED NAT TYPE OPEN. When u have NAT Type Open try this Force Host code:

Force Host [ON]:
set party_connectTimeout 1; set party_host 1; set party_hostmigration 0; set onlinegame 1; set onlinegameandhost 1; set onlineunrankedgameandhost 0; set migration_msgtimeout 0; set migration_timeBetween 999999; set migration_verboseBroadcastTime 0; set migrationPingTime 0; set bandwidthtest_duration 0; set bandwidthtest_enable 0; set bandwidthtest_ingame_enable 0; set bandwidthtest_timeout 0; set cl_migrationTimeout 0; set lobby_partySearchWaitTime 0; set bandwidthtest_announceinterval 0; set partymigrate_broadcast_interval 99999; set partymigrate_pingtest_timeout 0; set partymigrate_timeout 0; set partymigrate_timeoutmax 0; set partymigrate_pingtest_retry 0; set partymigrate_pingtest_timeout 0; set g_kickHostIfIdle 0; set sv_cheats 1; set scr_dom_scorelimit 0; set xblive_playEvenIfDown 1; set party_hostmigration 0; set badhost_endGameIfISuck 0; set badhost_maxDoISuckFrames 0; set badhost_maxHappyPingTime 99999; set badhost_minTotalClientsForHappyTest 99999; set bandwidthtest_enable 0"

Force Host [OFF]:
set reset party_connectTimeout; reset party_host; reset party_hostmigration; reset onlinegame; reset onlinegameandhost; reset onlineunrankedgameandhost; reset migration_msgtimeout; reset migration_timeBetween; reset migration_verboseBroadcastTime; reset migrationPingTime; reset bandwidthtest_duration; reset bandwidthtest_enable; reset bandwidthtest_ingame_enable; reset bandwidthtest_timeout; reset cl_migrationTimeout; reset lobby_partySearchWaitTime; reset bandwidthtest_announceinterval; reset partymigrate_broadcast_interval; reset partymigrate_pingtest_timeout; reset partymigrate_timeout; reset partymigrate_timeoutmax; reset partymigrate_pingtest_retry;reset partymigrate_pingtest_timeout; reset g_kickHostIfIdle; reset sv_cheats; reset scr_dom_scorelimit; reset xblive_playEvenIfDown; reset party_hostmigration; reset badhost_endGameIfISuck ; reset badhost_maxDoISuckFrames; reset badhost_maxHappyPingTime ; reset badhost_minTotalClientsForHappyTest ; reset bandwidthtest_enable""

I use this Force Host Code too and I don't have a good connection but I have NAT Type Open.
