Zolembedwa Zotsogolera Zapakompyuta
Cholinga cha IP Masquerading ndi kulola makina okhala ndipadera, osasinthika ma intaneti pa intaneti yanu kuti agwiritse ntchito intaneti kudzera mu makina omwe akugwedeza. Misewu yamtundu wanu wachinsinsi womwe umaloledwa pa intaneti iyenera kuyendetsedwa kuti ikhale mayankho kuti ikhale yobwereranso kwa makina omwe apanga pempho. Kuti muchite izi, kernel iyenera kusintha ma adiresi a IP apamwamba pa paketi iliyonse kuti mayankho adzibwezeretsedwe mmalo mwake, m'malo mwa adiresi yapadera ya IP yomwe inapanga pempholo, losatheka pa intaneti. Linux imagwiritsa ntchito Connection Tracking (conntrack) kuti idziwe kuti ndi ma makina ati ndi kubwezeretsanso paketi iliyonse yobwerera. Kupita pamsewu kuchoka pazithunzithunzi zanu payekha ndi "masqueraded" monga omwe adachokera ku makina anu opangira njira. Njirayi imatchulidwa mu malemba a Microsoft monga Kugawana Kwawo Pa Intaneti.
Malangizo Kwa IP Kusunga
Izi zingatheke ndi ulamuliro umodzi wa iptables, womwe ukhoza kusiyana mosiyana ndi makonzedwe anu:
sudo iptables -ndipo -POSTROUTING -s 192.168.0.0/16 -o ppp0 -j MASQUERADELamuloli pamwambapa likusonyeza kuti malo anu apadera ndi 192.168.0.0/16 komanso kuti chipangizo chanu choyang'ana pa intaneti ndi ppp0. Mawu omasuliridwawa akuphweka motere:
- -ndipo - lamulo ndilo kulowa mu tebulo
- -POSTROUTING - lamuloli liyenera kuyendetsedwa (-A) ku chain POSTROUTING
- -ndi 192.168.0.0/16 - lamuloli likugwiritsidwa ntchito pamsewu wochokera kudilesi ya adresi
- -o ppp0 - lamuloli likugwiritsidwa ntchito pazowonongeka kuti azitha kupyolera mu chipangizo chodziwika
- -j MASQUERADE - Mapepala ofanana ndi lamulo ili ndi "kulumpha" (-j) ku cholinga cha MASQUERADE kuti chigwiritsidwe ntchito monga tafotokozera pamwambapa
Mndandanda uliwonse mu fyuluta yowonongeka (tebulo losasinthika, ndipamene pulogalamu yamtundu wambiri kapena zonse zimakhalapo) ali ndi ndondomeko yosasintha ya kuvomereza, koma ngati mukupanga chowotcha moto powonjezera chipangizo cha chipata, mutha kukhazikitsa ndondomeko kuti mutenge kapena DZIWANI, panthawiyi magalimoto anu otetezeka akuyenera kuloledwa kupyolera mu mndandanda wa ZOKHUDZA kuti lamulo lilembedwe:
sudo iptables -ZIKHALIDWE - 192.168.0.0/16 -o ppp0 -j Kulandira zizindikiro zotsatila -ZIKHALIDWE - 192.168.0.0/16 -mdziko - LIMODZI, LIMODZI -i ppp0 -j KulandiraMalamulo apamwambawa adzalola kuyanjana konse kuchokera ku intaneti yanu ku intaneti ndi magalimoto onse okhudzana ndi malumikizowo kuti abwerere ku makina omwe adawatsogolera.
