Ubani okhetha i-MTU ye-WireGuard: i-wg-quick, i-kernel noma wena

I-WireGuard ayinayo ingxoxo ye-MTU. Ibhala ngokufihla konke okunikezwa i-interface bese ithumela umphumela, futhi uma iphakethe elisongelwe lidlula umzila, liyaphonswa noma lihlukaniswe endaweni ongayiboni. Othile kufanele akhethe i-MTU ye-interface, futhi lowo muntu yithuluzi elikhuphule i-interface.

Kunabantu abathathu abazongenela ukhetho, futhi kulula ukubadida.

Izindawo ezintathu inani elingavela kuzo

Inani lingasetwa ngokucacile ekumiseni kwe-interface, libalwe ithuluzi lokusetha kusuka olwazini lomzila, noma lisetwe yinoma yimuphi umphathi wenethiwekhi ophethe i-interface. Ucingo olujwayelekile lwe-wg alwenzi lutho kwalokhu, ngoba i-wg iphethe kuphela izikhiye nontanga. I-MTU ihlala ku-interface yenethiwekhi, yingakho i-ip link show wg0 iyindawo oyifunda kuyo.

Uma ungaqinisekile ukuthi yisiphi isimo esisebenza, funda i-MTU kuqala, bese uthola ukuthi ubani oqale i-interface.

Nquma ngokusekelwe kulowo ophethe i-interface

Uma i-wg-quick iyiqala, umugqa ocacile we-MTU uyanqoba, uma kungenjalo ibala inani. Uma umphathi wenethiwekhi uyiqala, iphrofayela yalowo mphathi iyanquma. Uma isimo sokusebenza samakhonteyina noma iklayenti lomhlinzeki siyiqala, funda imibhalo yabo esikhundleni sokucabanga ukuziphatha kwe-wg-quick.

Isinqumo akusona ukuthi iyiphi inombolo engcono ngendlela engaqondakali. Singukuthi yisiphi isigaba ongakwazi ngempela ukusimisa.

Ibalo elizenzakalelayo lenza ini

I-wg-quick ithola umzila oya endaweni yokugcina yontanga, ithatha i-MTU yaleyo interface ephumayo bese isusa izindleko zokufaka. Ngekhanda langaphandle le-IPv4 lokhu kucishe kube amabhayithi angu-60; nge-IPv6 kucishe kube angu-80. Umphumela uyanqunyelwa ukuze umzila wamabhayithi angu-1500 unikeze u-1420 esikhundleni senani elisebenza kuphela ohlwini olulodwa lwamakheli. Lokho kuyinani elizenzakalelayo elinengqondo, hhayi isilinganiso somzila wakho.

Ayikwazi ukwazi ngomhubhe wakamuva, isixhumanisi seselula noma umzila we-ICMP ohlungiwe.

Lo mkhawulo ufihla umbuzo wangempela. Uma umzila wakho ngempela ungamabhayithi angu-9000 kusuka ekupheleni kuya ekupheleni, u-1420 ushiya ukusebenza etafuleni, futhi uma umzila ungama-1400, u-1420 usukhulu kakhulu. Inani elizenzakalelayo liwukuvumelana, futhi kufanele liphathwe kanjalo.

Lapho umzila ushintsha ngaphansi kwakho

I-laptop ezulazula isuka ku-Ethernet iye ku-Wi-Fi bese iya endaweni yokuxhuma yocingo igcina i-MTU ye-interface eyaqala ngayo. Umzila wangaphandle manje ungase ube mncane, futhi akukho okuxoxisanayo kabusha. Imihubhe efakiwe yenza kube kubi nakakhulu, ngoba isigaba ngasinye sisusa izindleko zaso kwisabelomali esifanayo. Inani elasebenza ehhovisi akulona inani elisebenza esikhumulweni sezindiza.

Ukuxhawulisana kwakamuva kufakazela ukuthi izikhiye ziyasebenza. Akufakazeli lutho mayelana nokuthi amaphakethe amakhulu ayangena yini.

Hlola inombolo eyodwa ngesikhathi

Gcina uhlelo nendawo efanayo, shintsha inani elilodwa bese ulinganisa. I-ping -M do -s 1372 ihlola iphakethe lamabhayithi angu-1400 elinebhithi le-DF elimisiwe, futhi yilolo hlobo lwesivivinyo oludingayo. Uma izicelo ezincane zisebenza kanti ezinkulu ziyama, unenkinga yosayizi hhayi yomzila.

Shintsha i-MTU kuphela. Ukulungisa izinketho ezimbalwa zephakethe kanyekanye akukutshele ukuthi iyiphi eyayibalulekile.

Futhi ungakulindeli ukuthi ushintsho lwe-MTU luzolungisa umzila wokubuya ongekho, umthetho wokudlulisa noma ukwehluleka kwe-DNS. Nakho kudala izimpawu zokuntuleka kwethrafikhi, futhi kunezivivinyo zako. I-ncwadi ye-wg-quick ibhala ngokukhetha okuzenzakalelayo.
