« kdy: 22. 09. 2012, 17:39:41 »

aky to ma zmysel pri wirelesse, povedzme ze mas 4 kancelarie v kazdej 5 pocitacov. Das tam 24 portovy manazovatelny switch ktory vie vlan, urobis privatne vlany - kazda vlan pre kazdu miestnost...ktore vsetky budu komunikovat s gateway...ano? alebo je aj ina moznost ako to riesit okrem vlan switcha? Nechapem pointu, ked sa to robi ako nadstavba na routovanej sieti, alebo pri wifickach. VIe mi to niekto vysvetlit? dakujem

Sítě / Jaké porty používá ProFTPD?

« kdy: 21. 09. 2012, 18:30:05 »

Zdravim,
chcel som sa spytat ake porty vyuziva proftpd, kedze ho chcem prioritizovat na sieti...
Vyzera ze nie standardne 20,21... ale ze sa menia v roznom rozmedzi, je dobre nastavit staticky 20, 21 alebo sa to neodporuca?

Sítě / Re:Pomoc s mangle na router OS...

« kdy: 17. 09. 2012, 11:39:11 »

Vraj je treba vsade pouzit passthrough=no, lenze v tom pripade mi to mnozstvo trafficu nemarkuje.
Mal som to povodne v pre/postroutingu, co si myslite, v com je vhodnejsie urobit tieto iste pravidla? forward alebo pre/postroutingu?
Na tom istom stroji sa sucasne robi NAT, firewall a qos....
