AW: DD-WRT Router mit OpenVPN

Das mit der push route ist komisch gelöst.
Wenn das keinen tieferen Sinn für dich hatte oder nur ein "hab ich mal so gesehen" ding ist ändere es mal so in der Server config.

push "redirect-gateway def1"
push "dhcp-option DNS 8.8.8.8"

ggf. Poste mal server, wie client config hier.

AW: DD-WRT Router mit OpenVPN

Hab mir gedacht ich geb den Gateway einfach Numerisch vor....
Wegen den DNS, hab mir gedacht er soll auf die im Router eingetragenen DNS zugreifen....
Firewall Regeln hab ich bis jetzt keine eingetragen, ist das vl. dass Problem?

//EDIT

Lösung -> unter "Commands" hab ich folgendes eingetragen und unter "Save Firewall" gespeichert

iptables -I INPUT 1 -p tcp --dport 443 -j ACCEPT
iptables -I FORWARD 1 --source 10.8.0.0/24 -j ACCEPT
iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o br0 -j MASQUERADE
iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j MASQUERADE
iptables -I FORWARD -i br0 -o tun2 -j ACCEPT
iptables -I FORWARD -i tun2 -o br0 -j ACCEPT
iptables -t nat -I POSTROUTING -o tun2 -j MASQUERADE

Redict to default Gateway muss auf "Enable" sein

Ändere mal die Firewall Regeln. Du hast das alles da doppelt gemoppelt.

Code:

[FONT=Helvetica]iptables -I INPUT 1 -p tcp --dport 443 -j ACCEPT[/FONT]
[FONT=Helvetica]iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j MASQUERADE[/FONT]
[FONT=Helvetica]iptables -I FORWARD -i br0 -o tun+ -j ACCEPT[/FONT]
[FONT=Helvetica]iptables -I FORWARD -i tun+ -o br0 -j ACCEPT[/FONT]
