Kungani i-DNAT eya ku-127.0.0.1 idinga ukunakekelwa okukhethekile
Qonda i-route_localnet lapho uqondisa ithrafikhi yangaphandle ku-proxy eboshwe ku-loopback.
Insiza ilalela ku-127.0.0.1:1080. Umthetho we-DNAT uqondisa ithrafikhi engenayo kulelo kheli, kodwa ukuxhumana kuyahluleka. Insiza ingase ibe nempilo futhi umthetho we-NAT ungahambisana: amakheli e-loopback e-IPv4 athola ukunakekelwa okukhethekile kwezindlela.
I-route_localnet ye-Linux ilawula ukuthi amakheli e-127/8 athathwa njengamakheli e-Mars ngesikhathi sokuhamba kwezindlela. Inani layo elizenzakalelayo ligcina umngcele ojwayelekile we-loopback. Ukuhluka kwesixhumi esithile kungaba okubalulekile ekwakhiweni kwamabomu kokuhambisa kwangaphakathi.
Yikho okuchaza ukuthi kungani umthetho osebenza komunye umshini ungase uncike ku-sysctl ongayikopishanga. Kodwa lokho akusikho isizathu sokuvula le nketho yonke indawo.
Isimo sokuphepha siyashintsha kanye nomzila
Ukubopha ku-loopback kuvame ukusetshenziswa ngoba umsizi akanakho ukuqinisekiswa komuntu osebenzisa uhlelo. Uma ithrafikhi evela kwesinye isixhumi ingahamba iye lapho, ikheli lokubopha lodwa alisachazi izethameli ezingafinyeleleka. Khawulela imithombo yokungena, indawo ekuyiwa kuyo kanye nechweba kusethi yangempela yemithetho, kuhlanganise nethrafikhi ethi ingumthombo noma indawo ekuyiwa kuyo ye-loopback lapho kufanele khona.
Buyekeza isikhala samagama senethiwekhi equkethe insiza. I-loopback yesitsha ayiyona i-loopback yomsingathi, futhi ukushintsha ukulungiselelwa kwesixhumi somsingathi akudali umlaleli ngaphakathi kwesitsha ngokuzenzakalela.
I-rp_filter iphendula umbuzo ohlukile mayelana nokuqinisekiswa komzila womthombo. Ukuyicisha emhlabeni wonke akusona isisusa esijwayelekile sokuqonda ukuhamba kwe-loopback. Ngokufanayo, i-ip_nonlocal_bind iphathelene nokubopha amasokhethi kumakheli angewona awasekhaya, hhayi ukwenza lo mzila we-DNAT ube ngcono.
Ekugcineni, iphrothokholi eqondisiwe kufanele ihambisane nomlaleli. Ukuthumela ithrafikhi eluhlaza ye-HTTP noma ye-TLS kwichweba le-SOCKS kusadinga isihumushi; ukuhluka komzila akukwazi ukunikeza izingxoxo ezingekho.
