Nos accelerare OpenVPN In itinere OpenWRT. Versio alternativa sine ferro ad soldandum et extremismo ferramentorum.

Salvete omnes, nuper legit vetus articulus de quomodo accelerare possis OpenVPN In itinere, encryptionem ad separatam partem machinae intra ipsum itinerem conglutinatam transfero. Similem condicionem auctoris habeo—TP-Link WDR3500 cum 128 MB memoriae RAM et processore imbecilli qui encryptionem cuniculi omnino tractare non potest. Attamen, omnino nolebam in itinerem cum ferro ad conglutinandum ingredi. Mea experientia infra limitem est. OpenVPN ad separatam partem apparati cum subsidio in router in casu necessitatis.

negotium

Habemus encaminatorem TP-Link WDR3500 et Orange Pi Zero H2. Volumus Orange Pi encryptionem cuniculi in modo normali tractare, sed si quid ei acciderit, processus a Pi curabitur. VPN Ad encaminatorem remittetur. Omnes configurationes muri ignis in encaminatore ut antea fungi debent. Et in universum, additio apparatuum additorum perspicua et omnibus imperceptibilis esse debet. OpenVPN Per TCP, adaptorem TAP in modo pontis (pons-servitoris) operatur.

arbitrium

Loco connectendi via USB, unum portum itineris uti constitui et omnia subnalia coniungere quae pontem VPN ad Orange Pi habent. Evenit ut ferramenta corporaliter in iisdem retiacula ac VPN server in iter pendeant. Post hoc, eosdem ministros in Auriaco Pi instituimus et in itinere aliquem procuratorem constituimus ut omnes hospites advenientes mittat ad servitorem externum, et si Orange Pi mortuus est vel perpendat, tunc ad internus fallback server. Cepi HAProxy.

Sic evenit;

1. A clientis advenit
2. Si server externus unavailable
3. Si available, clientis accipitur ab Auriaco Pi
4. VPN in Aureum Pi decryptis facis et exspuens eos in iter
5. Iter itineris illis alicubi

Exemplum exsequendam

Dicamus igitur nos duas retia in itinere habere - principalem (1) et hospitem (2), pro utraque earum est... OpenVPN servitor ad connexionem ab externo.

Configuratione Network

Ambas retiacula per unum portum ad iter faciendum opus, sic 2 VLANs creamus.

Iter itineris, in sectione Network/Translate, VLANs crea (exempli gratia 1 et 2) easque in tagged modus in optatum portum, eth0.1 et eth0.2 ad retiacula correspondentia adde recentia creata (exempli gratia; eos brigde add).

In Orange Pi duos interfaces VLAN creamus (Habeo 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

Et statim duos pontes eis creamus;

/etc/netctl/br-main

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

/etc/netctl/br-guest

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

Admitte autostart pro omnibus 4 profiles (netctl enable). Nunc post reboot, Aureum Pi pendet in duobus ligula eget. Inscriptiones interfacies in Pi Orange in Static Leases itineris itineris configuramus.

VPN erigas

Deinde, configurationes ex itinere (vel "router") exscribimus pro OpenVPN et claves. Optiones plerumque ex /tmp/etc/openvpn*.conf

Defalta, openvpn currens in TAP modum et pons server-continuum suum custodit iners. Omnia enim operantur, necesse est scripturam addere currentem cum reducitur nexus.

/etc/openvpn/main.conf

dev vpn-main

ca /etc/openvpn/main/ca.crt
cert /etc/openvpn/main/main.crt

up /etc/openvpn/vpn-up.sh

/etc/openvpn/vpn-up.sh

#!/bin/sh

ifconfig vpn-${profile_name} up
brctl addif br-${profile_name} vpn-${profile_name}

Quo fit, ut primum nexus incidit, vpn-main interface addatur br-main. Requisitores hospites - similiter, usque ad nomen interface et inscriptio in server-ponte.

Petitiones externas et proxying profectus

Ad hunc gradum, Orange Pi, iam hospites accipere et clientes ad retiacula requisita coniungere potest. Reliquum est ut ineuntes nexus in itinere configurare procurationem.

Servientes iter itineris VPN ad alios portus transfermus, HAProxy instituimus in iter et configuramus:

/etc/haproxy.cfg

global
        maxconn 256
        uid 0
        gid 0
        daemon

defaults
        retries 1
        contimeout 1000
        option splice-auto

listen guest_vpn
        bind :444
        mode tcp
        server 0-orange 192.168.2.3:444 check
        server 1-local  127.0.0.1:4444 check backup

listen main_vpn
        bind :443
        mode tcp
        server 0-orange 192.168.1.3:443 check
        server 1-local  127.0.0.1:4443 check backup

Fruere

Si omnia secundum consilium iverunt, clientes ad Orange Pi et processus iter itineris amplius non calefaciet, et celeritas VPN signanter augebit. Eodem tempore omnes regulae retis quae in itinere commemorantur pertinentes manebunt. In casu accidentis in Orange Pi, defluet et HAProxy clientes ad loci servitores transferet.

Gratias tibi agimus propter diligentiam tuam, suggestiones et correctiones gratae sunt.
