    I think i found the problem for all those "connection lost" issues, help me finish it

    So, as a lot of people have been complaining on the forums abount those random "connection lost" issues (it has been happening with me aswell for quite awhile), i have been digging for answers all over the internet.

    None found.

    Today, i was checking my router's firewall logs and there they were. Logs about every DC i had in TS3.

    Now, there are two types of logs:
    FIREWALL replay check (1 of 1): Protocol: ICMP Src ip:"random ip from any part of the world, like russia, netherlands, romania" Dst ip: "my ip" Type: Destination Unreachable Code: Host Unreacheable

    IDS dos parser : udp flood (1 of 1) : "server ip" "my ip" 0108 UDP 9990->63402

    Being the first the most common on my DC's, can anyone help me out here?
    This may be the problem with most people aswell....

    Important notes:
    Before anyone asks:

    My packet loss is always very close to 0%
    TS3 client is allowed on my windows firewall, and my AV doesn't have built in firewall, so no questions there
    Problem is not with internet speed, as it is very stable and doesn't have anyother problem
    Yes, those random ip things are at the exact time of the connection issues on ts3

    Cheers, and awaiting for some feedback

    disable DoS if you can on your (router/modem) firewall.

    Because TeamSpeak3 uses UDP to send stream of data, it also tends to send a lot of packets.
    DoS is actually made to defend against attacks similar to this but its not able to tell if its teamspeak or really an attack.
    Actually even TeamViewer is sometimes logged in there.
    I also saw some router vendor implementations where in logs it said literally:
    "lan IP:port" to "ts3server:port" is DoS attacking.
    "lan IP:port" to "TeamViewerGuy:port" is DoS attacking.
