connected but no internet

Post by sdvpn » Thu Sep 07, 2017 2:22 am

Hi,

I setup openvpn server on my router running tomato firmware and I can connect to it but no internet. One special thing about my setup is that the openvpn server is on my second router (192.168.10.1). I do have my first router(192.168.10.2) port forwarding the vpn server port to my second router. The second router which has the vpn server has the first router as the default gateway and the DNS set to the DNS of my ISP.

I did some research and I ended up adding the DNS push commands on the server and settign the cipher to AES-256-CBC on the client. NEither change made a difference and for some reason the cipher keeps getting picked as AES-256-GCM.

after reading a bit I think there is something wrong with my firewall rules. But I am too sure if the issue is on the router with vpn server (internal) or the router it connects to (External)

iptables on vpn server router:

some of the stuff I ran into suggested adding :

Code: Select all

iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j MASQUERADE
but I dont know what that means and whether I should do it on the external or internal router..

I also found the sticky here with the chart on how to find my issue. I found that I could not ping 8.8.8.8 and it says to enable ip forwarding. But I don't know how to do that

okay I think I got it to work with:

Code: Select all

iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j MASQUERADE
thanks to viewtopic.php?t=12708

I thought I had done that already but I think I did it to the wrong router. I had to do it to do router with vpn server.

vpn server router:

Code: Select all

iptables -t nat -L

server config currently looks like:

Code: Select all

 Automatically generated configuration

proto udp
port 1194
dev tun21
cipher AES-256-CBC

push "redirect-gateway def1"
tls-auth static.key 0
ca ca.crt
dh dh.pem
cert server.crt
key server.key
status-version 2

# Custom Configuration
push "route 10.8.8.0 255.255.0.0"
dont know if any of the new stuff I added is also needed, but they didn't work without the iptables command above
