Openvpn works for 20 min, then a reboot is needed..?!?

retro

Hello,

I'm trying to get openvpn to work on my ddwrt router-

What I have done is getting an account at blackvpn.com.
After googling and reading allot, I found out that the router I was already using, Linksys E3000, was very suitable for running openvpn.
So I flashed the router after following the instructions on the ddwrt-site thoroughly with "dd-wrt.v24-15962_NEWD-2_K2.6_big-e2k-e3k".
I understand this is one of the most recommended, most stable versions. Correct..?

I then followed the instructions from blackvpn.com/support/dd-wrt-with-openvpn/.

And it worked..!

I was very happy for 20 minutes.
Then I loose the connection.
I then reboot the router and it works for another 20 minutes..

This is not my area, but I guess it has to do with dns-servers, right..? Crying or Very sad

A tech from blackvpn made an effort to help me, but he really didn't have a clue...

So I put my trust in you guys...please help a newbie.. Wink ..?

Below is a logfile from ddwrt, please have a look and tell me what's wrong..?
(I have masked the IP-adresses)

No-one..?
Have I posted in the wrong forum..?

Really would like some help on this...

maikcat

hi there,

can you please also post in ddwrt forum as well?,

also

at least try to format log text correctly.. (have you tried to read it? 🙂 )

if you install openvpn on a pc ,do you experience the same disconnections?
if yes its not router/ddwrt fault....

Michael.

There are two things here which can help you getting a better response. One is the way the log looks like, the other one is more my personal "requirements".

1. Paste a readable log. What you pasted here is so hard to read that I don't have patience to try to decode it - as I have much more fun things to do than decoding random log files.

2. You're using DD-WRT ... I personally have a big dislike for DD-WRT, as they don't really care about security at all.
<rant>
Google 'littleblackbox' and you'll find all the different encryption keys shipped with DD-WRT by default. Which can be used to break into your router, if somebody wants to. DD-WRT's response was that it doesn't matter because "users should know they shouldn't enable https on the public interface or use ssh without re-generating the keys" ... did you think about that when you configured your router? And there are other incidents as well - as hard coded iptables (firewall) rules, enabling access from fixed IPs - and they didn't really care about informing their users about it; but cared more about shutting down the discussion threads on their own forum instead. My recommendation: Don't ever consider using DD-WRT if you care about security. At least never deploy it on a network with a public IP address.
</rant>
For an alternative to DD-WRT ... look into OpenWRT, where OpenVPN works like a charm and without any hickups at all. OpenWRT also have an open and sane developement and user community and not just a bunch of fanboys. And it's actually some companies distributing TP-Link wr1043nd devices with OpenWRT and OpenVPN as part of their commercial ISP offerings. Regarding Linksys E3000 and OpenWRT, I see they're working on getting full support. Another option might be Tomato, but I haven't looked at that one for ages so I don't know about its status.

But if you insist on DD-WRT, I'm not able to provide any help on that platform; I don't trust it and it would be wrong of me making you believe you'll be safe with such a setup. But if others are able/willing to do that, be my guest.

Hello,

First, thanks for your replys guys..!

maikcat;

Yes, I have posted in the ddwrt-forum. No response...

Sorry about the log. I just dont know how to format it and I thought it would be best to post it untoutched.
How can I make it easier to read..?
However, I have cut out the part where the problems start, after 20min. I'll post it at the end of this post.

Yes, I do have openvpn on my pc also, there it works 100%, so it should be the router, right..?

dazo;

I didn't know ddwrt was insecure, no. The main reason I chose blackvpn was that they actually had installation instructions for ddwrt for a novice like me... 8-)
And I already had the Linksys laying around, so...

But if you suggest going openwrt instead, which is the best router to get at the moment..?

I have now flashed my router with Tomato USB instead. Anyone that could help me get it running with openvpn..please... 😉
Is the info on https://www.blackvpn.com/support/dd-wrt-with-openvpn/ enough to get it working..?
