Hello !
I will try to explain very well my issue.
I have created a IPsec tunnel between a Mikrotik HAP AX2 and a Fortigate 60F. I was able to make the full remote browsing works (The Mikrotik uses the internet connection of the Fortigate side).
My problem is : I have 1Gbs Fiber in the Fortigate side, and 600 Mbps in the Mikrotik side. When the tunnel is up, PC of my Mikrotik LAN can only reach 29 Dld/ 5 Mbs Upld maximum, so maybe I made something wrong.
I tried to change all encryption method to see any improvment, no luck,
I tried to up the tunnel from my home where I have only 40 Mb/s, and I have the same behavior, the maximum bandwith is 29 mb/s in download.
I checked that the Hardware acceleration is up and yes it is.
If someone have an idea of the root cause, It would be very appreciated.
Have a nice day
