these things never work: default gateway, dns, win

[deleted]

everytime i try to add a push route to my server config(other than the rerouting all internet traffic) i get error messages.

i'm running a ddwrt router with openvpn server, and a windows 7 client.

my regular LAN is on 10.22.1.1, openvpn is giving addresses on 10.22.2.0

if i connect with only the reroute traffic, like normal, i have to go into my networking settings and set DNS server's manually to 8.8.8.8 8.8.4.4, and everything works like it should. if i type ipconfig /all it shows no default gateway, i can access the router at 10.22.2.1 though.

so i try to get it to show my default gateway by adding route-gateway 10.22.2.1 and everything stops working, i cannot access router anymore at any address. i cannot browse web.

so how do i add a default gateway, dns, and win is my question? here is my server config.

dh /tmp/openvpn/dh.pem
ca /tmp/openvpn/ca.crt

did you try

push "dhcp-option DNS x.x.x.x"
push "dhcp-option WINS x.x.x.x"
push "route-gateway x.x.x.x"

what does the *client* report when these settings are pushed by the server? You can also add then directly to the client config using

dhcp-option DNS x.x.x.x
dhcp-option WINS x.x.x.x
route-gateway x.x.x.x

remove

route-gateway 10.22.2.1

from your client config - this is causing the routing errors. Reconnect and post the client log file again.

i already knew that :O that was the original complaint! i just don't know WHY it messes it up. guess i'd have to be a linux administrator networking specialist and take classes and stuff :lol:

ok back to the real world.

removing the route-gateway worked great, however, i was still having the "unknown network" error in windows, and couldn't see any of my home computers in networking(i still can't btw even after applying this small fix)

adding

route-metric 512
route 0.0.0.0 0.0.0.0

magically made the network recognized; and i could still browse internet, connect to router, and do all my original stuff.

only thing left to do is figure out how to see my home LAN computers through the DD-WRT router/openvpnserver.

in this setup there is only my laptop with windows openvpn-gui, my router with DD-WRT, and my home LAN desktop computer.

adding

route 0.0.0.0 0.0.0.0

is equivalent to specifying

redirect-gateway

on the client , while the server is pushing out 'push "redirect-gateway def1" '

after the vpn client connects it will send packets with source IP 10.22.2.6 ; this network range needs to be known to the default GW on the server side LAN (which I assume is the dd-wrt box). You can try reaching other machines on the server side lan , first by pinging an IP on your server LAN - if that works then IP connectivity works.
