Hello
My Name is Cedric. I have a customer which two sites. On every site is an ISR4431. I use a DMVPN tunnel with NHRP Protocol.
On both side is a line with 500Mbit/s WAN access. My problem is now, that I have not more then 200Mbit/s over the VPN Tunnel.
When I make a speedtest directly to Internet, I receive my full 500Mbit/s.
I checked the licenses and there is no fragementation problem. Below the Tunnelconfig and additional information.
Is there a licensing problem or technical problem?
