Region : Argentina

Model : TL-ER6120

Hardware Version : V1

Firmware Version : 1.0.7 Build 20140113 Rel.63736

ISP : FiberCorp


Hi Everybody!!

I'd installed phisically TL-ER6120 and 10 TL-R600 Vpns routers connected each one to internet ok.

Then 'd configure IKE and IPSec rules for each VPN Tunnels and its works ok.

I'd only activated 3 Tunnes for testing and its works perfectly!!! Till............. Suddently after few days all the vpn tunnels breaks down.... :-(

I'd rebotted the TL-ER6120 and started to work again perfectly, but in a few days the vpn broke again.....

Anyone have the same problem? I've the lastest firmware for the TL-ER6120

Thanks!!!!

I will check it, but, could be possible that the r600vpn client router is not with the latest firmware hang up the tl-er6120 with all the vpn tunnels activated?I only reboot the tl-er6120 and starts working all well till a few days...

I'd checked all the TL-R600VPN routers and all are with the lastest firmware avaiable:

1.2.3 Build 140801 Rel.49374n

I dont know what could it be...

The solution for me at the moment its to reboot the TL-ER6120 each time vpn's tunnels go down... :-(

I was analysing my IPsec configurations.... Anyway when all of the tunnels are activated and working well, I configured each diferent IPSec Policy (for each vpn) with the same IPsec proposal (I mean, same IPsec proposal for all IPsec policies)..., and in the same way, for each IKE policy with a unique IKE Proposal (Same IKE Proposal for all IKE Policies).

Maybe this kind of configuration makes the TL-ER6120 tilt.... I dont know..... for a day works perfect...then...out....

You'd better contact TP-LINK support team and provide some screenshots or config files for them to verify and test.

SOLVED!!!!!!!!!!!!! I'd contacted to TPLINK support and they provide several tips to me and I'd reconfigured the IPSec Policies with DPD interval at 20 secs. Now, the 10 VPN tunnels are working fine !!! Thanks!!!
