Maybe I'm misunderstanding you, maybe not - but what exactly do you mean by
"the ping from the server is always 300ms"?
Is it the ICMP ping (generated by the 'ping' tool), or do you mean when you
play Counter-Strike, and you look at the players tab, that shows you're
lagged with 300ms?
Have you tried to ping the counter-strike server direct from the shell using
the 'ping' tool? If this results in very low ping replies, your tc setup is
correctly set up.
The only thing you're missing now, is to prioritize counter-strike specific
traffic. Usually the portnumbers used by Couter-Strike servers are 27015 and
some numbers up, so this is what you have to prioritize.
An example (class id is from your first script, using htb) - this will put
the packets leaving your $IF_EXT to port 27015, 27016 and 27017 to any hosts
in the class 1:1:
for cs_p in 27015 27016 27017; do
tc filter add dev $IF_EXT parent 1:0 protocol ip prio 10 u32 \
match ip dport $cs_p 0xffff flowid 1:1
done
You may need to modify the above example to fit your script.
