Failing to connect multiple routers DD WRT

revisHi, Any help getting connected appreciated please. I have 2 routers on my network. They do not run in bridged mode and router b has dd wrt on it is connected to router A and addressed as a DMZ client device from router A. I think the issue that I am having is DNS, though I am unsure. I have had open vpn running using TorGuard from router B successfully in the past.

WEB -> ROUTER A (192.168.1.1) -> DMZ to WAN IP ADDRESS ROUTER B (192.168.1.100) -> ROUTER B LOCAL IP ADDRESS 192.168.2.1

I've telnetted router B and here is the conf for open vpn.

ca /tmp/openvpncl/ca.crt

cert /tmp/openvpncl/client.crt

key /tmp/openvpncl/client.key

management 127.0.0.1 5001

management-log-cache 50

verb 4

mute 5

log-append /var/log/openvpncl

writepid /var/run/openvpncl.pid

client

resolv-retry infinite

nobind

persist-key

persist-tun

script-security 2

mtu-disc yes

dev tun1

proto udp

cipher aes-256-cbc

auth sha1

remote 31.193.12.74 443

tls-client

tun-mtu 1500

comp-lzo yes

ns-cert-type server

fast-io

auth-user-pass /tmp/password.txt

persist-key

persist-tun

tls-client

remote-cert-tls server

Hello!

Is router B trying to connect to AirVPN? If so, the OpenVPN configuration has several mistakes (wrong authentication type with username/password, wrong tls client directive - beware it's repeated twice..), please revert to the configuration provided by our configuraton generator.

Kind regards

Hi,

Thanks for help on this. I was able to verify the settings by checking the open vpn log in dd wrt and also when generating the connection log which I included as a value in the openvpn conf...

log-append /var/log/openvpncl (for anyone else looking for help on this)

I used WinSCP instead of SSH for ease on this.

I now get a connection to your service which is great, however, it appears that my connection loads as tun1 and not tun0, is this usual? Do I change your firewall setup to reflect this. I am having issues now with port forwarding. From what I have read I need to disable the NAT rules I have set up on my router pre airvpn and if I want to forward a port from the tunnel to a machine on my network I use the following command and save it in the DD WRT startup... (remote desktop to machine 192.168.2.102 on may lan)

iptables -t nat -I PREROUTING -i tun1 -p tcp --dport 3389 -j DNAT --to-destination 192.168.2.102

I am no expert as you have by now guessed but I was wondering if this if correct or does the firewall rules you have for DD WRT just map to the existing NAT on my router?

iptables -I FORWARD -i br0 -o tun0 -j ACCEPT iptables -I FORWARD -i tun0 -o br0 -j ACCEPT iptables -I INPUT -i tun0 -j REJECT

iptables -t nat -A POSTROUTING -o tun0 -j MASQUERADE

Thanks again for help!

Hello!

Yes, that's normal.

Do I change your firewall setup to reflect this.

Yes, it is mandatory: replace tun0 with tun1.

I am having issues now with port forwarding. From what I have read I need to disable the NAT rules I have set up on my router pre airvpn and if I want to forward a port from the tunnel to a machine on my network I use the following command and save it in the DD WRT startup...

It appears correct, assuming that the network card of the device you wish to forward port 3389 TCP to is 192.168.2.102. Of course do not forget to remotely forward port(s) on our system (menu "Member Area"->"Forwarded ports").

Kind regards

Hi, Thanks again for your help. I am almost on the cusp of being properly set up and need some more advice please. I have had tunnel working with port forwarding on and off. When left idle for sometime and trying to connect to the web I was having no success. Looking at the openvpn log I could see the following....

Thu Dec 20 05:09:02 2012 us=940767 MANAGEMENT: Client connected from 127.0.0.1:5001

Thu Dec 20 05:09:02 2012 us=945820 MANAGEMENT: CMD 'state'

Thu Dec 20 05:09:02 2012 us=946874 MANAGEMENT: Client disconnected

My config...

ca /tmp/openvpncl/ca.crt

cert /tmp/openvpncl/client.crt

key /tmp/openvpncl/client.key

management 127.0.0.1 5001

management-log-cache 50

verb 4

mute 5

log-append /var/log/openvpncl

writepid /var/run/openvpncl.pid

client

resolv-retry infinite

nobind

persist-key

persist-tun

script-security 2

mtu-disc yes

dev tun1

proto udp

cipher aes-256-cbc

auth sha1

remote 31.193.12.74 443

tls-client

tun-mtu 1500

comp-lzo yes

ns-cert-type server

fast-io

tls-cipher AES256-SHA

DD WRT will always overwrite the openvpn config with whatever it reads from the DD WRT GUI settings. The line 127.0.0.1:5001 does appear in the conf which I can't figure how to remove so I commented my own iptable rule that used port 5001 too as I assumed a conflict and did a reboot. (commented...)

#iptables -t nat -I PREROUTING -i tun1 -p tcp --dport 5001 -j DNAT --to-destination 192.168.2.101

I then rebooted and open vpn would not connect to your service but this time with an auth error. Checked the certs and all good nothing changed. (Sorry about log paste, add file not working for me)

Again I thought this may be my iptables rules so I commented everything that wasn't for the moment vital rebooted the router again and the tunnel started running.

Hello!

Before proceeding on further troubleshooting, please try a connection to 443 TCP and 80 TCP. The logs show some replay-window backtracks which suggest packet loss (or a replay attack - very unlikely but if you live in some very human rights hostile country it's an option that must be taken into consideration). Try to change VPN server as well.

Finally, please attach a screenshot of the DD-WRT web interface OpenVPN configuration.

Kind regards

Hi,

I am connecting on 443, not in a hostile country and without air running can access these ports fine. I've done some homework and there are suggestions on chmod 600 on the cert files and also maybe running as a daemon. Which I assume is setting up via the server/daemon option in DD WRT. Do I need to have 443 open on my firewall/ it appears to me the openvpn port is auto selected and I do not need to open the firewall?

Where is the screen shot?

Thanks again....

Hello!

About your firewall, you just need to make sure that outbound port 443 is not "blocked", but surely it is fine, because you reach without problems OpenVPN servers listening to port 443.

You should be able to access the OpenVPN configuration panel through the web access to your DD-WRT router. Once you're there, please take a snapshot of the screen.

Kind regards

Hi, I think it was me being very dull. The subnet was not set on the router config on the openvpn client section on the router. Seems to be working fine now. Thanks for help.
