Hi everyone, I could use some help today. We're experiencing some
unusual WAN latency issues. We have a setup using a pair of
FortiGate-120G and FortiGate-100F devices with a WAN configured in LACP
with 2x1Gb links. The network connection is structur...
Hello, Recently, I upgraded all my FortiGates from FortiOS 7.2.6 to
7.4.5. After several weeks with no issues, I took a closer look at my
configuration and noticed an unusual increase in IPSec VPN errors.
Specifically, the TX error counter on the IPS...
Hello, I'm running a LACP MCLAG on a couple of FortiSiwtch-1024D

LACP is correctly configured and works properly. I can down an interface

Hi Johnathan, Thanks for your response. After some test, if I reduce the
bandwidth around 500Mbps the latency is now "normal". Between my
environnement and my FAI, I have two 1GB link with copper (connected on
10Gb switches). I suspected the copper m...
I continued my tests and tried downgrading my FortiGate to version
7.2.10, but observed the same behavior on this release. Therefore, I
suspect there might be something unusual in my configuration, likely
related to MTU/MSS settings. I can reproduce ...
Hi, According to my post here :
https://community.fortinet.com/t5/Support-Forum/FortiGate-VPN-IPSec-Tx-Error/td-p/356096
I'm actually running FortiOS 7.4.5 and I can notice tx error on VPN
tunnel (on PPPoE only). After some deep search and a lot of t...
Hello AEK, Thanks for your response. The tx error is equals to 0 on WAN
