Hi kotusha1

 

ER6020 should be able to set up multiple VPN tunnels. 

Now you can ping ER6020 but cannot establish the VPN tunnel? Please make sure you have set up two IPsec VPN entries. If you are convenient, please post your configuration. Please note to hide your IP address.

This are the two tunnela connected on router TL-ER6020, I changed IKE and ipsec credentials on tunnel 2 to test it that was the problem, but it it did not change a thing.

 

Information tunnel 1 - Gateway Side TL-ER6020 (The one working)

 

 

This is the branch side router TL-R600VPN

 

 

This is the tunnel that does not allow packages, only to the router 600vpn.

 

configuration on router TL-ER6020

 

 

 

 

This is the branch side router TL-R600VPN

On branch side I'm able to ping the whole network (600VPN)

 

 

On Main Office side (TL-ER6020) can only ping the router (600VPN)

I have disable Dos attach Defense, but still does the same.

According to the information you provided, the VPN tunnel was already established. 

Do two R600VPN use the same firmware version? And you said that one VPN tunnel can work, one VPN tunnel has problem. Did you ping the same device? If the devices you ping are different, you can try to check the firwall of the deivces. Like Windows PC, we need to disable its firewall if we want to ping it.

 

For ER6020, you also can try to upgrade the latest beta firmware.

1.- I'd backup the configuracion of the working router, and restored it to the not working router.

2.- Disable the working router.

3.- Still the vpn tunnel does not work, I can only see the router.

 

This means that there is a malfuntion with the router 600vpn or a problem with the internet connection.

 

I will move the router to another location to see if it will work in another internet connection tomorrow.

The testing result that move the router to another location will be the important reference. Did you know any difference between two of your network?
