<p class=MsoNormal><font size=2 face=Arial><span lang=EN-US style='font-size:
10.0pt;font-family:Arial'>Na serveri, cez ktory bezi internet na lokalke, mam
firewall na ip & mac, obmedzujuci internetovy pristup iba na spravne
kombinacie ip a mac adresy. Setko je ok, ale spojazdnil som transparent proxy
(squid) a nastal problem – obmedzenie na IP funguje stale (podla
konfiguraku squid), ale uz mi ignoruje mac adresy, teda ktokolvek si moze
nastavit IP registrovanej sietovky a dostane sa na internet. Zrejme dochadza v
proxy k zmene hlavicky packetov na lokalne adresy, alebo jako, a teda sa
prepustaju cez firewall. Neda sa predradit iptables pred proxy – aby prve
obmedzenie bolo na iptables a az potom proxy, alebo nejakou konfiguraciou
squida?<o:p></o:p></span></font></p>
