Recently I have been experiencing a slow connection to the Internet. I
have an ADSL connection 1500/256 with iptables running, which, I suspect
is causing the slowdown.
Typically I get ping times of about 2000 ms, and something like 20%
packet loss, though both are highly variable. If I turn off iptables,
then I get speeds like 200-250 ms, and much lower packet loss.
I suspect, but am certainly not sure, that this started to happen when I
used Webmin to turn on bandwith monitoring, which I have since turned
off. There seem to be a few residual changes in my configurations.
Is there anything I can look at?
