Hello everybody,
First thing I would like to write is I am sorry for my bad english.
I´m not sure, if this isn´t bad topic, bud we can´t figure our trouble out.
We are using http://www.ispadmin.eu/ for controling our clients and APs list but we since about november 2011 we discovered weird issue.This program, that automatically configure mikrotik firewall rulez from time to time set the same rule twice or more times.For example we drop every adress in 192.168.5.xxx except of users that are added by this program. So normally for example in some AP there is firewall rule #1 action = accept user 123 with ip 192.168.5.10.And of course in this case rule #2 will be drop 192.168.5.0/24.That is ok, but in some unknown situations, this programe don´t delete these old rulez first and only add the same rule under another rule id.
Problem is when we have in one “mikrotik unit” about 50 firewall rulez and this program all of these rulez add second or even five times…
If there is about 150 rulez in RB 433, this mikrotik slow down and in the end totally freeze and we have to localy reboot unit and remove and add that 50 rulez that should be there…
We are not sure if this is happening because of some mikrotik OS version or it is randomly but it is really annoying to almost every week solving this issue.
Thanks for every idea that can solve our bad sleeping
