Fortigate 60D ISP speed limit

[hanifannuman]

i just want to check i have upgrade the ISP line 800 download 200 upload
when i do speed test internal network i get 110 download 110 upload
but when direct ISP router i get 700++ download 150++ upload
this is becuase the fortgate 60D box limit or setting?

Hello,

      If ask  ISP to switch from PPPoE to DHCP will can't  obtain IPv6 address.

Well, that is a limitation on the ISP side then.
Explain to them the reason you can`t use PPPoE. That might somehow force them to provide you a solution

First-level support usually has limits. You have to ask for higher-level support.

Dear aahmadzada,

tq for you advise i will apply this setting after operation hours.

Thank You,

I believe the role of the interface should be set to WAN and the bandwidth has to be configured on the interface. The devices detect the speed from the speed of the physical interface. It could not know the speed of the link connected to the router. This causes a problem with WAN optimization devices.

Dear Mohamed Gaber,

mean need to config wan interface bandwidth?

Thank You,

No,the operational is vain. Beacuse when Fortigate 60D use PPPoE is handled by PPP software process and connections are terminated in virtual interfaces. Therefore PPPoE connection cannot be offloaded to the hardware and can`t be accelerated.
