I-VPN iyaxhuma kodwa ayifinyeleli amadivaysi e-LAN: yini okufanele ihlolwe

Ithrafikhi ingena emhubheni, isango liphendula ekhelini lalo, futhi akukho lutho oluphendulayo ngemuva kwalo. Lelo phethini livamile futhi akukona ukuphikisana: impendulo evela esangweni ifakazela ukuthi umhubhe uphelile, futhi ayifakazeli lutho mayelana nokwenzeka epheketheni elikhethelwe ngale kwalo. Izivivinyo ezimbili zisebenzisa izindlela zekhodi ezihlukene emshinini owodwa.

Kusukela manje zama okuthile ngakolunye uhlangothi lwesango. Ikheli lesango uqobo lizoqhubeka liphendula, noma ngabe ukudlulisela kugqekeze kangakanani.

Isango liphendula kusuka kusiteki salo

Iphekethi elikhethelwe isango lihanjiswa endleleni yalo yokufaka yasendaweni, lapho i-kernel inquma khona ukuthi i-socket elalelayo iyolamukela yini. Iphekethi elikhethelwe isibambi esingemuva kwesango lihanjiswa esikhundleni salokho endleleni yokudlulisela, lapho kusebenza khona iqoqo elihlukile lokuhlola. Ukudlulisela kungavalwa ngokuphelele, noma i-kernel ikuvule bese umthetho wokuhlunga ongalokothi ukhulume ngomhubhe uyenqabe. Akukho kulokhu okuthinta impendulo yesango uqobo, yingakho uphawu ludukisa ngokuthembeka kangaka.

Amakhasi okuphatha afinyelelwa ngomhubhe nawo angaphansi kwesigaba sokuqala. Ayibufakazi ngomhubhe, hhayi ngomthelela wamanethiwekhi ongemuva kwawo.

Landela ukugeleza kuze kufike umngcele wokuqala okulahla

Qala kukhasimende futhi uqinisekise umzila nekheli lomthombo okuzowusebenzisa ukugeleza. Bese ubheka isango ukufika kwalokho kugeleza okuqondile, futhi uphinde ubheke ukugeleza okufanayo kuphuma libheke e-LAN. Uma kungafiki neze, inkinga isohlangothini lwekhasimende noma kumaphrefiksi avunyelwe omhubhe. Uma kufika futhi kungaphumi neze, inkinga isekudluliseleni noma kusihlungi sendlela yokuya phambili, futhi ukuthwebula sekusho ukuthi yikuphi.

Ukwenza isivivinyo esifanayo kusuka esangweni kufihla ingxenye ethokozisayo, ngoba iphekethi elivela esangweni linomthombo ohlukile kanye nemfuneko ehlukile yokubuya. Sebenzisa ukugeleza kwekhasimende, nekheli lako lomthombo uqobo, esinyathelweni ngasinye. Ukuthwebula okuthathwe kusixhumi esingalungile kuveza ubudlwembe obuzethembayo.

Imizila yokubuya kanye nezindonga zomlilo zesibambi kwehluleka ngokwehlukana

Lapho iphekethi lifinyelela isibambi, kufanele kube khona ezinye izinto ezintathu. Isevisi kufanele ilalele ekhelini okwathunyelwa kulo iphekethi, udonga lomlilo lwesibambi kufanele lwamukele, futhi impendulo kufanele ibe nomzila wokubuya obheke echibini lamakhasimende. Okokugcina kwehluleka kaningi, ngoba umzila ozenzakalelayo wesibambi ukhomba kwi-router engakaze izwe ngobubanzi bomhubhe. Umphumela uwukuxhumana okusungulwa ngokombono wesibambi futhi kufe buthule kolunye uhlangothi.

Zama umzila wokubuya ngamabomu ngokuthumela kusuka kukhasimende nokubuka ukubuya. Ukuthwebula kohlangothi olulodwa kunquma ngemizuzwana lokho okungeke kukunqume ihora lokucabanga.

Qinisekisa isinyathelo ngasinye ngekheli lomthombo lekhasimende

Gijimisa izivivinyo ngokulandelana futhi gcina yonke imiphumela, ngoba inani lisekuqhathaniseni, hhayi emugqeni oyedwa. Imiyalo engezansi ibeka ikheli lomthombo, ikhombisa umzila okhethiwe futhi ithwebula izinhlangothi zombili zokudlulisela. Shintsha isibambi sakho se-LAN nesixhumi somhubhe.

ip route get 192.168.50.20 from 10.8.0.2
ping -I 10.8.0.2 -c 3 192.168.50.20
sudo tcpdump -ni tun0 host 192.168.50.20
sudo tcpdump -ni br0 host 192.168.50.20

Umbuzo womzila ukhombisa ukuthi ikhasimende lingayithumela yini leyo phekethi emhubheni, futhi i-ping ikhombisa ukuthi kukhona okubuyile yini esibambini. Ukuqhathanisa ukuthwebula okubili kuhlukanisa ukufika nokuphuma, ngoba uhlaka esixhumeni somhubhe olungenasilingani esixhumeni se-LAN yisinqumo sokudlulisela, hhayi ukwehluleka kwesevisi. Lapho ukuthwebula kokubili kukhombisa isicelo futhi okukodwa kuphela kukhombisa impendulo, umzila wokubuya ungumsolwa osele.

Rekhoda ukuthi yiliphi ikheli eliphendulile nokuthi yisiphi isikhombisi esidlulisiwe esihlulekile. Lowo musho wenza umbiko usebenziseke esikhundleni sesimangalo sokuthi iseva ayifinyeleleki.
