Salutare ,
am si eu o mica problema cu cateva calculatoare care sunt virusate
intr-o mica retea de "cartier" .... folosesc ip-uri private in
interioriul retelei si apoi din NAT ies aproape toate print-un singur
ip de net , problema mea este ca din 2 in 2 saptamani acel ip este
listat in "XBL" , acum stau eu si ma intreb daca incerc sa limitez
numarul de conexiuni smtp pe FORWARD rezolv cumva problema ?
cu un iptables -A FORWARD -s 192.168.2.0/24 -p tcp --dport 25 -j LOG
il gasesc pe omu` care este virusat dar il gasesc destul de tarziu si
as vrea o alta solutie , iar daca se poate nu as vrea sa ma ridic
la "standardele" RDS si sa tai de tot portul 25 de tot , mi se pare o
chestie destul de "ciobaneasca" sa-l filtrez de tot .....
so .... are cineva vreo idee ? s-a mai lovit cineva de asta si a gasit
o solutie ?
Multumesc
