How to use DDNS ervice

elrodvpn

Hi, I'm very new to using openvpn but recognize this is likely a dumb question so please bear with me. I searched the forums but it's all over my head!

I am on ubuntu linux. I want to have it boot up with the vpn connected (complete). I want my ddns service (in my case noip2) to use my ISP's assigned address and not the VPN server address - which is unfortunately does once the VPN is connected. How do I do this? My VPN provider suggested I use the route command to specify a path to the noip server but I don't understand exactly how to do this.

Thanks!

Add to your config file

route-nopull

Hi, thanks for the suggestion.
That makes using the VPN a user choice for each connection right?
What I would like to do it have the VPN used for ALL connections EXCEPT for the noip server. Is that possible?

I tried using the route command to specify that noip use my own gateway.

sudo route add -host www.no-ip.com gw 192.168.0.1

It seemed to work (no vpn in the traceroute path anymore):

eric@mythtv:~$ traceroute www.no-ip.com
traceroute to www.no-ip.com (8.23.224.110), 30 hops max, 60 byte packets
1 192.168.0.1 (192.168.0.1) 3.516 ms 3.478 ms 3.456 ms

12 www.no-ip.com (8.23.224.110) 250.138 ms 272.332 ms 59.620 ms

BUT, noip still came up with the vpn server ip address.

Any other ideas?

Sorry for all the messages to myself! ;-)

I had the url wrong for the dynamic ip resolver service.

I did this:
sudo route add -host dynupdate.no-ip.com gw 192.168.0.1

And my noip.com service works fine now with the vpn on.

Hope this helps some other noob.
