openVPN chyba v routovani

Ahoj,

chtěl bych poprosit o radu s openVPN připojením server-client. Konkrétně mám 2 routery RT-AC55U(server) a RT-AC51U(client). Server má dynamicky přidělenou veřejnou IP a subnet 192.168.1.0/24. Client má staticky přidělenou veřejnou IP a subnet 192.168.100.0/24.

Cílem je, abych se ze sítě pod routerem (z ip 192.168.1.20) dostal na adresu 192.168.100.20 a naopak.

Konfigurace serveru:

#Automatically generated configuration daemon server 192.168.200.0 255.255.255.0 proto udp port 1194 dev tun21 comp-lzo adaptive keepalive 15 60 verb 3 push "route 192.168.1.0 255.255.255.0 vpn_gateway 500" duplicate-cn plugin /usr/lib/openvpn-plugin-auth-pam.so openvpn ca ca.crt dh dh.pem cert server.crt key server.key status-version 2 status status 10

Myslím, že v routovací tabulce serveru bych měl mít route na subnet 192.168.100.0 ne? Jak mám docílit spojení? Spojení Client-server funguje, ale spojení server-client už ne.

Díky moc za pomoc.

Myslím, že v routovací tabulce serveru bych měl mít route na subnet 192.168.100.0 ne? Jak mám docílit spojení? Spojení Client-server funguje, ale spojení server-client už ne.

Díky moc za pomoc.

---- Citace ----

Server má dynamicky přidělenou veřejnou IP a subnet 192.168.1.0/24. Client má staticky přidělenou veřejnou IP a subnet 192.168.100.0/24.

---- END CITACE ----

A na tom jsi byl kde že adresy 192.168.x.y jsou veřejné?

Tyto adresy jsou neveřejné, a pokud nemáš někde na internetu stroj s veřejnou IP nebo nemá aspoň jeden router veřejnou IP tak to nepůjde!

Takže si nejdříve něco o tom přečti a pak se zeptej s lokální IP to fakt nejde.

On ten server i klient mají oba nejspíš na jednom rozhraní veřejnou a na druhém lokální síť. Co myslíš?

Ano, přesně tak to je, samozřejmě má vnější síť WAN a pak vnitřní LAN... viz routovací tabulky. Lan jsem ponechal, WAN je přepsaná...

V tom dotazu se ale podle mne nic takového nepíše ;) Citace říká, že router má veřejnou IP a(!) (uvnitř) subnet ...

Výpisy jsem pročetl jen zběžně, ale skutečně tam minimáloně chybí ta zpětná routa do sítě klienta.

PS. Teď koukám na ty routovací tabulky, jasně že obráceně musíš mít na serveru záznam že 192.168.100.x síť musí odcházet tunelem.

Zkus do configu serveru přidat 
route 192.168.100.0 255.255.255.0 ip_pridelena_vpn_klientovi
Zbytek už bude případně o doladění firewallu.

Když do configu přidám: 
route 192.168.100.0 255.255.255.0 192.168.200.6
což je virtuální adresa přidělená klientovim vyhodí mi to v logu error: 
Mar 11 13:28:47 openvpn[21601]: /sbin/route add -net 192.168.100.0 netmask 255.255.255.0 gw 192.168.200.6
Mar 11 13:28:47 openvpn[21601]: ERROR: Linux route add command failed: external program exited with error status: 1
Možná protože v době, kdy se zadává route příkaz, není ještě připojený klient?

Když zadám: 
route 192.168.100.0 255.255.255.0 192.168.200.1
nebo 
route 192.168.100.0 255.255.255.0 192.168.200.2
Tedy pustit to přes ptp sítě, viz: 
Mar 10 23:38:12 openvpn[7534]: /sbin/ifconfig tun21 192.168.200.1 pointopoint 192.168.200.2 mtu 1500
Route to vytvoří, ale nedopingnu se.

Při zadávání route přes SSH mě to prostě za boha nechce pustit přes gw 192.168.200.6 (i když je klient už připojen).

Btw mohu nějak v client.ovpn nastavit, jakou bude mít klient IP? Tedy např 192.168.200.10?
