Na-emewanye OpenVPN na rawụta Openwrt. Ụdị ọzọ na-enweghị ígwè na-agbaze na extremism ngwaike

Na-emewanye OpenVPN na rawụta Openwrt. Ụdị ọzọ na-enweghị ígwè na-agbaze na extremism ngwaike

Ndewo onye ọ bụla, m gụrụ na nso nso a ochie edemede banyere otu ị ga-esi mee ngwa ngwa OpenVPN na rawụta site na ịnyefe nzuzo na ngwa ngwa dị iche, nke a na-ere n'ime rawụta n'onwe ya. Enwere m ikpe yiri nke ahụ na onye edemede - TP-Link WDR3500 nwere megabytes 128 nke RAM na ihe nrụpụta adịghị mma nke na-enweghị ike ịnagide nzuzo nzuzo ọwara. Otú ọ dị, achọghị m nnọọ iji ígwè na-ere ere banye na rawụta. N'okpuru bụ ahụmịhe m nke ịkwaga OpenVPN gaa na ngwaike dị iche yana nkwado ndabere na mpaghara rawụta ma ọ bụrụ na enwere ihe mberede.

Ebumnuche

Enwere TP-Link WDR3500 rawụta yana Orange Pi Zero H2. Anyị chọrọ ka Orange Pi zoo ọwara dị ka ọ na-adị, ma ọ bụrụ na ihe emee ya, nhazi VPN ga-alaghachi azụ na rawụta. Ntọala firewall niile na rawụta kwesịrị ịrụ ọrụ dịka ọ dị na mbụ. Na n'ozuzu, ịgbakwunye ngwaike ndị ọzọ kwesịrị ịbụ nke doro anya na onye ọ bụla na-adịghị ahụta ya. OpenVPN na-arụ ọrụ n'elu TCP, ihe nkwụnye TAP nọ na ọnọdụ akwa mmiri (ihe nkesa-akwa).

mkpebi

Kama ijikọ site na USB, ekpebiri m iji otu ọdụ ụgbọ mmiri nke rawụta wee jikọọ subnets niile nwere akwa VPN na Orange Pi. Ọ tụgharịrị na mpempe ngwaike ahụ ga-adagide n'otu netwọkụ dị ka sava VPN na rawụta. Mgbe nke ahụ gasịrị, anyị na-etinye otu sava ahụ na Orange Pi, na rawụta anyị na-edozi ụdị proxy ka ọ na-eziga njikọ niile na-abata na ihe nkesa mpụga, ma ọ bụrụ na Orange Pi anwụọla ma ọ bụ adịghị adị, wee gaa na ihe nkesa fallback nke ime. Ana m ewere HAProxy.

Ọ tụgharịrị dị ka nke a:

  1. Onye ahịa abịarute
  2. Ọ bụrụ na ihe nkesa mpụga adịghị, dị ka ọ dị na mbụ, njikọ ahụ na-aga na nkesa nke ime
  3. Ọ bụrụ na ọ dị, Orange Pi na-anabata onye ahịa ya
  4. VPN dị na Orange Pi na-ewepụ ngwugwu ma fesa ha azụ na rawụta
  5. Ndị rawụta na-eduga ha ebe

Ihe atụ mmejuputa

Yabụ, ka anyị nwee netwọkụ abụọ na rawụta - isi (1) na ọbịa (2), maka nke ọ bụla n'ime ha enwere sava OpenVPN maka ijikọ na mpụga.

Nhazi netwọkụ

Anyị kwesịrị ibugharị netwọkụ abụọ ahụ site n'otu ọdụ ụgbọ mmiri, yabụ anyị mepụtara VLAN 2.

Na rawụta, na ngalaba Network / Gbanwee, mepụta VLANs (dịka ọmụmaatụ 1 na 2) wee mee ka ha nwee ọnọdụ mkpado na ọdụ ụgbọ mmiri achọrọ, tinye eth0.1 na eth0.2 emepụtara ọhụrụ na netwọkụ kwekọrọ (dịka ọmụmaatụ. tinye ha na brigde).

Na Orange Pi anyị na-emepụta oghere VLAN abụọ (Enwere m Archlinux ARM + netctl):

/etc/netctl/vlan-main

Description='Main VLAN on eth0'
Interface=vlan-main
Connection=vlan
BindsToInterfaces=eth0
VLANID=1
IP=no

/etc/netctl/vlan-guest

Description='Guest VLAN on eth0'
Interface=vlan-guest
Connection=vlan
BindsToInterfaces=eth0
VLANID=2
IP=no

Anyị ozugbo mepụtakwara ha àkwà mmiri abụọ:

/etc/netctl/br-main

Description="Main Bridge connection"
Interface=br-main
Connection=bridge
BindsToInterfaces=(vlan-main)
IP=dhcp

/etc/netctl/br-ọbịa

Description="Guest Bridge connection"
Interface=br-guest
Connection=bridge
BindsToInterfaces=(vlan-guest)
IP=dhcp

Kwado autostart maka profaịlụ anọ niile (netctl nwee ike). Ugbu a ka ịmalitegharịchara, Orange Pi ga-adagide na netwọkụ abụọ achọrọ. Anyị na-ahazi adreesị interface na Orange Pi na Static Leases na rawụta.

Ọzọ, detuo ntọala maka OpenVPN yana igodo sitere na rawụta. Enwere ike ịhụ ntọala na ya /tmp/etc/openvpn*.conf

Site na ndabara, openvpn na-agba ọsọ na ọnọdụ TAP na sava-bridge na-eme ka interface ya ghara ịdị irè. Ka ihe niile wee rụọ ọrụ, ịkwesịrị ịgbakwunye edemede na-agba ọsọ mgbe njikọ na-arụ ọrụ.

Ntugharị arịrịọ na mpụga yana proxying

Na nzọụkwụ a, Orange Pi enweela ike ịnakwere njikọ yana jikọọ ndị ahịa na netwọk achọrọ. Naanị ihe fọdụrụ bụ ịhazi proxying nke njikọ mbata na rawụta.

Anyị na-ebufe sava VPN rawụta na ọdụ ụgbọ mmiri ndị ọzọ, wụnye HAProxy na rawụta wee hazie:

/etc/haproxy.cfg

        maxconn 256

Nwee obi ụtọ

Ọ bụrụ na ihe niile na-aga dị ka atụmatụ si dị, ndị ahịa ga-agbanwe na Orange Pi na onye na-ahụ maka rawụta agaghịzi ekpo ọkụ, ọsọ VPN ga-abawanye nke ukwuu. N'otu oge ahụ, iwu netwọk niile edebanyere aha na rawụta ga-anọgide na-adị mkpa. N'ihe banyere ihe mberede na Orange Pi, ọ ga-adaba na HAProxy ga-ebufe ndị ahịa na sava mpaghara.

Daalụ maka nlebara anya gị, a na-anabata aro na mmezi.
