Okufanele ukugcine kukhophi yokusekela ngaphambi kokuthinta izilungiselelo ze-VPN ze-routa
Ukukhipha ikhonfigurashini akulona uhlelo lokubuyisela. Bhala phansi okhiye, inguqulo ye-firmware kanye nendlela yokubuyela emuva ngaphambi kokushintsha isilungiselelo se-VPN kurouta.
Inkinobho yokukhipha ikunikeza ifayela, futhi lelo fayela liyingxenye encane kakhulu yokulungela. Okusindisa kakhulu ubusuku ukwazi ukuthi yiziphi izingxenye lelo fayela elizishiyayo, ukuthi uzobuyela kanjani kurouta lapho kuyi-tunnel eyonakele, nokuthi ukubuyisela ngeke kususe ini. Bhala lezi zinto ezintathu ngaphambi kokuvula ikhasi le-VPN. Awukho umsebenzi onzima, futhi yikho kanye okwenza uhlehliswe.
Ukukhipha kuqukethe ini ngempela
Kumafirmware amaningi erouta, ukukhipha kuyisethi yezilungiselelo: ama-interface, imithetho ye-firewall, ukubekelwa kwe-DHCP, ukulungiselelwa kwe-VPN futhi ngokuvamile nokhiye abayimfihlo abahamba nakho. Ngakho lelo fayela elilodwa liqukethe izimfihlo, okushintsha lapho lingagcinwa khona nokuthi ubani angalifunda.
Futhi akuvamisile ukuphelela. Iphrofayela ingakhomba ezintweni zokhiye, amafayela ezitifiketi noma amaphakheji okungawatholi ukukhipha kwezilungiselelo, futhi ukubuyisela kudivayisi esanda kufakwa i-flash kuzobuyisa isikhombisi ngaphandle kwento okukhombiswa yiyo. Funda imibhalo ye-firmware mayelana nobubanzi bokukhipha esikhundleni sokucabanga ukuthi ifayela liyisithombe sediski sesimo sakho sokusebenza.
Bhalisa ifayela uma i-firmware ikunikeza lokho, futhi uligcine endaweni engeyona i-routa uqobo. Ikhophi yokusekela ehlala kuphela kudivayisi eliyichazayo iyanyamalala ngaso leso sikhathi lapho uyidinga khona. Phatha ukukhipha njengesitoreji sezikhombo eziyikho ngempela, ngoba yikho eliba yikho ezandleni zomunye umuntu.
Bhala phansi okuncikile okuzungezile
Ifayela lezilungiselelo alinanjongo ngaphandle kokwazi ukuthi lingokani. Bhala imodeli, inguqulo ye-firmware, iphrothokholi esetshenziswayo kanye nendima edlalwa yile routa. Bhala la maqiniso endaweni lapho i-routa ingadingeki khona ukuze uwafunde.
Imininingwane emine inquma ukuthi ukubuyisela kuzosebenza yini:
| Item | Where to record it | What breaks without it |
|---|---|---|
| Firmware version | Next to the backup file | Restore rejected or silently partial |
| VPN keys and certificates | Separate encrypted copy | Device restored, tunnel cannot authenticate |
| WAN and LAN addressing | Paper or offline note | Cannot reach the admin page afterwards |
| Out-of-band access | Console or management port | No path back in when the tunnel fails |
Umgqa wokugcina yiwona amantu awudlulayo. Uma indlela yakho eyodwa eya kurouta idlula kuyi-tunnel ozoqalaza ukuyilungisa, uzihlelele ukuzivalela ngaphandle ngesikhathi esibi kunazo zonke.
Qala ngokubhala indlela yokubuyisela
Ngaphambi kokushintsha noma ini, bhala izinyathelo ozozilanda uma i-routa ingasafinyeleleki: iyiphi intambo, iyiphi imbobo, iyiphi ikheli, iyiphi i-akhawunti. Bese ulandela lezo zinyathelo kanye ngesikhathi i-routa isasebenza. Qinisekisa ukuthi i-console noma i-interface yokuphatha iyaphendula ngesikhathi konke kusebenza, ngoba ukuthola i-console ephukile ngemva kokuphahlazeka kuguqula ukubuyela kwemizuzu eyishumi kube ukuvakasha endaweni.
Faka encwadini ngisho inqubo yokubuyisela, hhayi igama lefayela kuphela. Umuntu ozoyifunda kungenzeka kube nguwe: ukhathele, ngesikhathi esingalungile, ungenaso ngisho isikhumbuzo sokuthi ifayela laya kuphi.
Buyisela, bese uhlola ukuthi kwabuya ini
Ukubuyisela okuqediwe akusiso inethiwekhi esebenzayo. Hlola izingxenye ezibuyela buthule kokumisiwe: izilungiselelo zesixazululi se-DNS, imithetho ye-firewall eyayikhomba ku-interface endala, kanye nanoma yimuphi umzila owawukhomba kusango lwe-tunnel. Vula imithetho eyahlelwa kabusha ngesikhathi sokuhlola bese uyiqhathanisa nalokho okwakukukukhipha. Umthetho obanzi wokuvumela owengezwe phakathi kwamabili futhi wakhohlwa ekuseni uhlala ngemva kwakho konke ukubuyisela, ngoba uyingxenye yefayela olishaye kabusha.
Kudivayisi yesitayela se-OpenWrt imiyalo ewusizo iphrinta i-tunnel ephilayo, ithebula lemizila kanye nempendulo yesixazululi evela kuyi-routa uqobo:
wg show
ip -4 route
nslookup example.com 192.168.1.1Bese uhlola kusukela kuklayenti evamile hhayi kuyi-routa. I-tunnel eyenza i-handshake kudivayisi kodwa amaklayenti engakwazi ukuxazulula amagama iyinkinga yenqubomgomo, futhi izobonakala njenge-VPN ephukile kubo bonke ngaphandle komuntu ophethe i-console.
Ukubuyisela akukulungisi ini
Ukubuyisela ukhiye akususi lutho, futhi akutsheli ukuthi zingaki izikhala ezikhona. Uma isizathu sokubuyela emuva kwakuyidivayisi elahlekile, ukukhipha okwabiwe noma ukusolwa kokugangwa, ukhiye omdala usasebenza noma kuphi lapho kukhona ikhophi, futhi ikhonfigurashini ebuyiselwe iwusebenzisa futhi.
Shintshanisa noma susa i-peer ngokusebenzisa inqubo esekelwa yisevisi, bese ubuyekeza i-routa kanye neklayenti esaphethe indwangu endala. Ikhophi yokusekela imelela isimo sokusebenza esaziwayo; ayimeleli isimo esiphephile esaziwayo, futhi umehluko ubalulekile khona lapho idivayisi ilahlekile.
