Hello,
The root of my problem was this:
> [0:0] -A SYNFLOOD -m limit --limit 1/s --limit-burst 4 -j RETURN
> [0:0] -A SYNFLOOD -j DROP
> [0:0] -A CHECK -p tcp -m tcp --tcp-flags SYN,RST,ACK SYN -j SYNFLOOD
When the HTTP/FTP-clients etc. spawned several connections (in this case
>4) to download files, the router blocked them.
I guess that it adds protection to keep the SYNFLOOD check there. What
are sensible values to use on -m limit, making it work for flooding, yet
not stopping normal clients?
Thanks guys,
Svein
