Title: VPN connection drops after 12 minutes
Post by: DigitalE on July 16, 2010, 10:43:32 AM
Hello,
I have a DIR-615, hardware version: C1, firmware version 3.12NA and my issue is that it keeps dropping my VPN connection after 12 minutes.  Sometimes it'll go longer than 12 minutes but on average right at 12 minutes of my connection, it drops.  This happens whether I'm using the wireless or hard wired to the router.  As a test, I ran a continuous ping on a computer on my internal network and also to a computer on my corporate network.  When I'm VPN'd in, both pings are successful.  Once the router kills my VPN session, the pings to my internal network are successful.  So the router isn't rebooting or anything like that.  My VPN session will automatically reconnect, but I'm stumped.  Any ideas?

Thanks!

Well, I downgraded to firmware 3.11 and the problem has gone away.  Looks like 3.12NA was the issue.

Same here , can confirm Fware  3.13NA does NOT fix the issue either... is there another workaround besides downgrading the FWare?

Hi friends,

I'm suffering this same issue. The hardware that I have is E3, firmware 5.10.
In my case there isn't a fix time, like as everybody mentioned.
I tried with the previous version, but without success. Any ideas?

Regards!

Need more info on your VPN's. Also, who is your ISP? What kind of modem. There really is almost no info in those posts except firmware.

In my case, the MODEM is DSL-500B.
I'm not sure if the problem is on ISP, because before to use the DIR-615, I was using another router (other brand) without this issue, I mean, the VPN connection doesn't drop.
Just to add, this issue occurs wired and wireless.
I came back with my old router, and this issue doesn't occur.

Your right, the ISP specifically doesn't matter, but PPPoE vs DHCP does matter. DSL is usually PPPoE

1. Who set up your first router?

2. Are you using PPPoE or PPPTP?

3. What kind of protocol is your VPN using? IPSec?

4. What kind of support do you get from your IT?

5. Is there any hardware involved with the VPN? Settings on your PC? Software installed on your PC?

6. Does your connection work on other computers not using a VPN when it drops on the one using your VPN?

Answering your questions:
1) myself
2) PPPoe
3) VPN is from JUNIPER
4) -
5) No, there isn't any kind of hardware. The software is from JUNIPER
6) Yes, it not using VPN, the intenet is connected all the time

Quite simple....I drop off this router into the garbage!!!
Unfortunately the DLINK support is poor, very poor....
My solution was solved when I bought another router (another brand), that it's working fine, without this issue and many other that I found. I decided to forget this brand, DLINK. I'm concerning my relatives and friends to buy the same router that I did, to not have the headache that I had.

I applaud the initiative of this independent group, but it's incredible that the company, like as DLINK, doesn't do anything to solve the problem that the customers have.
Applying the firmware that exist in this forum, it's clear that DLINK doesn't want to be responsible for this product more. I'm very disapointed with DLINK....

I do understand the frustration you have with this router however sometimes these routers are only doing as they are designed to do. I can't sat for sure however some routers do not have some abilities like other models. This could be a case of maybe this router model just doesn't have the full capabilities to handle VPN stuff like other routers and models. Maybe this router was mainly for just general mom and pop home user networking. I do believe in general that most routers should handle some of not most of todays networking however this just might depend on what the OEMS are developing and what they want to put in to there routers. Dlink has made some great products and as other OEMS as well. Sometimes its the user that needs to understand a bit more about there needs and make more appropriate decision when buying networking equipment as well. Do some research on routers, ask questions, get all the info before going to buy something. I wish you luck with your new router.

Unfortunately, questions like as VPN is not covered in the product data sheet or technical manual, and in the time that I was searching about this router, this point was not covered. Before to acquire this router, I had another old router (another brand), and this old router didn't have any issues regarding on VPN, so I thought the newest products, like as DIR-615, would work like my old router, but with more feature, like as "N" support. Sure, if I found any comment regarding this kind of issue, I never had bought. But unfortunately many issues just appear when somebody try to apply to a specific application. I understood that this kind of products can show issues along the time, but it's important that the manufacturer opens his mind and has for wish to fix it.
I'm understanding the game, I disagree but I respect.
I hope that in the future, DLINK comes to change this way, and assume the responsability to fix issues and not let this responsability to independent group.

I'd also recommend you to contact one of the moderators on here as well. DLink does watch the forums.

My configuration is DIR-615 Hardware E3 Firmware version 5.10.

I had the same issue of my VPN software(Juniper Network Connect) dropping and reconnecting every 12 min or so. I seem to have fixed it by unchecking the ALG Configurations and changing the NAT Endpoint Filtering to Endpoint Independent setting. Both these options are under the Firewall section in the web based administration. I unchecked all ALG configurations though you can probably just uncheck the IPSec one and it might work. Also,  I changed the NAT endpoint filtering for both UDP and TCP.

Give it a shot if you are still having issue. Firmware changing seems too drastic for something as basic as VPN connection.

Unfortunately I have the same router model and firmware and have the same issues with dropping the VPN, but that is not all.....many times a session with firefox when refreshing the browser or going to a new page, i get "the connection was reset" msg....and when i hit the "try again" button, it goes through normally...same thing happens with IE, it just gives it's own lost connection msg.....I upgraded from a G router that never had a problem, hoping to get a faster connection.....but youtube videos, clips, etc will hang/stutter because of this issue.....I'm about ready to spend money I don't have to get the dir-825 to stop being annoyed......anybody know of a definitive solution that works??

What HW version is your router?
What FW version is currently loaded?

What ISP Service do you have? Cable or DSL?
What ISP Modem do you have? Stand Alone or built in router?
What ISP Modem make and model do you have?

Ensure DNS IP addresses are being filled in under Setup/Internet/Manual?
Turn off QoS options.
Turn off Advanced DNS Services if you have this option.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices on the router.
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP.

What wireless modes are you using?
Try single mode G or mixed G and N?
What security mode are you using? WEP, WPA or WPA2? Preferred is WPA2.
What wireless devices do you have connected?
Any cordless house phones?
Any other WiFi routers in the area?

Turn off all anti virus and firewall programs on PC while testing.
Turn off all devices accept for one wired PC while testing.

I've been having this problem as well. I did as this response suggested and changed "NAT Endpoint Filtering" to Endpoint Independent and am having more success. THanks for the tip! Did anyone else succeed?

I apologize if it's bad form to resurrect a 2-year old thread, but I'm just extremely happy and grateful that I found this thread. Though I have a different router (I have the DHP-1320), I had the exact same problem: every 12 minutes my Juniper Network Connect session would disconnect, and it was driving me nuts. I changed the NAT endpoint filtering for both TCP and UDP to be Endpoint Independent, and this problem seems to be completely fixed.

Thank you so much for posting this!     :)
