Hello,
I would like to limit the connections to 100 per 255.255.255.0
Is there a chance e.g. to zero the last byte of "$binary_remote_addr"?
Something like:
set $remote_addr_24 "/$remote_addr/\.[0-9]*$/.0/"
limit_zone connectiontrack $remote_addr_24 16m;
limit_conn connectiontrack 100;
Thanks a lot
Markus
