I-router noma ikhompyutha ehlukile njenge-VPN server yakho: ukukhetha kanjani

Kokubili i-router nekhompyutha encane kungaqeda i-VPN, futhi isinqumo asivamisile ukuncika kumthamo wokudlulisela. Sincika ekutheni ubani ofaka isibuyekezo ngesikhathi samabili ebusuku, yini enye ema lapho lelo bhokisi liqalisa kabusha, nokuthi ingabe usengafinyelela ikhonsoli lapho kuyi-tunnel uqobo ophukile. Phendula le mibuzo emithathu kumuntu ngamunye obeqokwa, futhi ukukhetha ngokuvamile kuzenzela kona. Inqubo engezansi iguqula ukuqhathanisa kube uhlu olufushane lwezinto ongazihlola ngaphambi kokuzibophezela.

Qala ngalokho okufanele kuqhubeke kusebenza lapho i-tunnel yehluleka

Ukwehluleka okufanele kuklanyelwe kona yilapho inqubo ye-VPN ifa kodwa usadinga ukufinyelela isibungu. Ku-router, i-tunnel nesango le-inthanethi kwabelana ngesiphetho esisodwa: ushintsho olulodwa olubi lwesetho lungawisa kokubili, futhi indlela yokubuyisela ngokuvamile ukusetha kabusha ngokomzimba. Ekhompyutheni ehlukile, isango liqhubeka lisebenza futhi isibungu sisafinyeleleka nge-LAN. Yimuphi kule miphumela ongayibekezelela onquma okuningi kunanoma yiluphi uhlu lwezici.

Bhala impendulo njengomusho owodwa: uma isibungu se-VPN siqalisa kabusha, umuzi noma ihhovisi ulahlekelwa ini? Uma impendulo ihlanganisa konke ukufinyelela kwe-inthanethi, usamukele indawo yokwehluleka eyabiwe futhi kufanele ukusho lokho ngamabomu esikhundleni sokukuthola kamuva.

Insizakalo yesibili kudivayisi eyodwa akuyona ikhonsoli yokugcina. Iyabelana ngokunikezwa kwamandla, i-firmware kanye ne-akhawunti yomlawuli.

Bala izindawo zokulungisa ezingezwa yisibungu ngasinye

I-router iletha i-firmware yomkhiqizi enesigqi sayo sokukhishwa, futhi isici se-VPN ngokuvamile i-module eyodwa ngaphakathi kwesithombe esikhulu kakhulu. Ikhompyutha iletha uhlelo lokusebenza, umphathi wamaphakethe, i-kernel kanye neqoqo lezinsizakalo manje ezingezakho. Kokubili kudinga amaphakethe okulungisa, futhi umbuzo wangempela ukuthi yisiphi isigqi ozosigcina lapho ubusha budlula.

Kusibungu se-Linux, yenza leso sigqi sibonakale esikhundleni sokuthemba kuso. systemctl list-timers ibonisa imisebenzi ehleliwe futhi apt list --upgradable ibonisa okulindile. Bhala ukuthi yiziphi izibuyekezo ezidinga ukuqalisa kabusha, ngoba isibungu se-VPN esiqalisa kabusha siwukuphazamiseka ngaphandle uma usikuhlelile. I-router engenayo indlela yokubuyekeza ezenzakalelayo idinga ukufakwa kwekhalenda esikhundleni, okuwukulawula okubuthakathaka kodwa okuqotho.

Bala nama-akhawunti futhi. Ukungena ngamunye komlawuli okwengeziwe kusibungu se-VPN kungenye imininingwane yokugunyaza okufanele iphendulwe kanye nomunye umzila okufanele uhoxiswe.

Landela umzila wenethiwekhi yangasese, hhayi ilebula elisebhokisini

Amaklayenti awanandaba nokuthi iseva isebenza kuphi; anandaba nokuthi iziqalo ezivikelwe ziyafinyeleleka yini nokuthi ikhona yini indlela yokubuya. Beka iseva lapho ukuhambisa kukulula kakhulu, okuvamise ukusho ngqo esigabeni esiphethe izinsiza. Ikhompyutha engemuva kwe-router isadinga ukudluliswa kwembobo, futhi izinsiza kuleyo LAN zisadinga umzila obuyela ku-subnet ye-tunnel.

Hlola ukudluliswa kusibungu ngaphambi kokusola iklayenti. sysctl net.ipv4.ip_forward kufanele ibike u-1, futhi nft list ruleset noma iptables -S ibonisa ukuthi isixhumi se-tunnel sivunyelwe ukudlulisa yini nhlobo. Umthetho we-masquerade ongekho ubonakala kusuka ohlangothini lweklayenti ufana ncamashi ne-tunnel ephukile.

Nquma futhi ukuthi i-tunnel akufanele ifinyelele ini. Iseva ebekwe ku-router ibona yonke i-subnet ehambiswa yileyo router, futhi lokho kuvamise ukuba ngaphezulu kwalokho okuhlosiwe umgomo wokufinyelela. Kusibungu esihlukile, ukwahlukaniswa okufanayo kusemgqeni owodwa wothango lomlilo, futhi indawo yomonakalo evela kuklayenti elihlaselwe incane. Incazelo yesango le-IPsec ku-RFC 7296 ithatha lokhu njengombuzo wokuhambisa nomgomo, hhayi wezingxenyekazi, futhi asikho isimo esiphephe kakhulu ngokuzenzakalelayo kuze kube umgomo ubhaliwe.

Gcina ikhonsoli yokubuyisela engathembele ku-tunnel

Ikhonsoli oyisebenzisayo ukulungisa i-VPN ayikwazi ukuba yi-VPN ngokwayo. Gcina ikheli le-LAN, ikhonsoli yochungechunge noma ikhonsoli yomhlinzeki esebenza ngesikhathi i-tunnel iphansi, futhi uyisebenzise okungenani kanye ngaphambi kokuba uyidinge. Umzila wangaphandle komkhawulo ongakaze uqeqeshwe uyuhlelo hhayi amandla.

Yenza ikhophi yokulondoloza yesetho endaweni ukuyo isibungu uqobo engakwazi ukuyisusa. tar -czf vpn-config-2026-11-03.tar.gz /etc/wireguard /etc/openvpn ibamba okhiye nezincazelo zensizakalo, futhi ikhophi kumele iphume emshinini. Faka imithetho yothango lomlilo kanye nohlu lwamaklayenti, ngoba ukubuyisela okhiye ngaphandle kohlu lozakwabo kukhiqiza iseva okungekho muntu ongayijoyina. Gcina ingqikithi endaweni ikhonsoli yokubuyisela engayifinyelela.

Bhala isinyathelo sokuhlehla kumbhalo ofanayo. Ushintsho lwesetho ngaphandle kokuhlehla okubhaliwe luwushintsho oluhlala njalo, noma ngabe yayini inhloso.

Qinisekisa ukukhetha ngokuqalisa kabusha nangesibuyekezo

Hlola ukuhlelwa ngendlela ezohluleka ngayo, hhayi ngendlela esebenza ngayo ngosuku oluhle. Qalisa kabusha isibungu, sebenzisa isibuyekezo esilindile, futhi qinisekisa ukuthi i-tunnel iyabuya ngaphandle kwezinyathelo zesandla.

Ngemuva kokuqalisa kabusha, hlola izinto ezintathu ezivame ukuphuka. systemctl is-active wg-quick@wg0 ibika ukuthi isixhumi sabuya yini, ss -lunp ibonisa ukuthi kukhona okulalela embobeni yini, futhi wg show ibala uzakwabo onokuxhawhana okuqediwe. Insizakalo esebenzayo ngaphandle kokuxhawhana isho ukuthi uthango lomlilo noma umzila awulungile, hhayi i-daemon.

Phinda ukuhlola kusuka kuklayenti ekunethiwekhi ehlukile kunaleya owahlela kuyo. Uma i-tunnel idlula ukuqalisa kabusha, isibuyekezo nokushintsha kwenethiwekhi yeklayenti, ukukhethwa kwesibungu sekunqunyiwe okwamanje. Uma kungenjalo, ingxenye engekho ngokuvamile iyisinyathelo esibhaliwe hhayi elinye ibhokisi.
