OpenVPN No Internet Access Clients

[TBP]

I have just set up an OpenVPN server on my router running Gargoyle.
I can connect and access the router user interface but I can not access the internet.
I think it is not getting access to the DNS server from the router.
On my iPhone (3G connected) it works if I have "Google DNS fallback" checked in the OpenVPN app.
On Windows 7 machine (tethered to iPhone 3G with VPN off on iPhone) no internet when connected and network classed as "undefined" by windows.

Let me know if you find a solution.
I noticed tonight it doesn't let me connect to a shared folder on another device as well.
I was able to get the internet working by setting the DNS servers manually.

ispyisail do you think it has anything to do with this routing?
Below is from the client log

PUSH: Received control message: 'PUSH_REPLY,topology subnet,route-gateway 10.8.0.1,redirect-gateway def1,ping 25,ping-restart 180,route 172.22.20.0 255.255.255.0 10.8.0.1,ifconfig 10.8.0.3 255.255.255.0'

My router is setup as 172.22.20.1 not 0 ?

I've got two active VPN sites

With one site when connected (VPN) I loose internet connection but can connect to clients using IP address

With the other site when connected (VPN) I have a internet connection and can connect to clients using IP address

I have not investigated the problem but I suspect that it is something to do with settings

I would suggest you do a "failsafe reset" to clear all setting and start again

ispyisail do you think this from hsk in another post would work with 1.6.2 and fix my problem?

I've solved the problem by adding these missing lines:

Code: Select all

config forwarding 'lan_vpn_forwarding'
        option src 'vpn'
        option dest 'lan'

to /etc/config/firewall manually, and restarting firewall (/etc/init.d/firewall restart).

I'm not sure if this is the cleanest solution, anyway, it works for me.
(Gargoyle 1.7.x with DIR-825 B1 fat)

I'VE TESTED:
Ping from VPN subnet to LAN subnet works. (vice versa)
FTP connect from VPN subnet(Client) to LAN subnet(Server) works.
