policylerinizi kontrol edin ve tcp udp servisini kapatın lütfen
sırası ile
yeterli olmaz ise antivirus,ips,fileblock işlemlerini kapatıp deneyin
anlık olarak cpu memory durmunu aşağıdaki linke göre izleyiniz

selamlar
selam savas abi, ilgine tesekkur ederim ancak sorunumu cozumleyemedim. 20-24 pc arasinda degisen bir agin onunde calisyor cihazim ve extra olarak diger lokasyondaki cihazla arasinda vpn var. 1 sene kadardir sikintisiz kullaniyordum. pc sayisinda bir artis bant genisligini daha yogunkullanma gibi bir durum olusmadigi halde ne sikinti yaratti anlayamadim. kaldiki bir takim ozelliklerinden feragat etmekte cihazi devreden cikartmak gibi geliyor bana 🙂
abi sakasi bir yanada tcp udp servisini kapatmak disinda(nasil yapacagimi bulamadim) senin dediklerinide denedim ayrica nette buldugum bir takim seyleride denedim ama degisiklik olmadi (detaylari asagidadir)
hardware olarak artirim yada software guncellemeyle bellek kullanim yetenegi arttirilamiyormu ( kullandigim os versiyon : Fortigate-60B 3.00-b0726(MR7))

ayrica yaptigim islemler
* Memory Log’u devre disi birakin. (Log&Report > Log Config > Log Setting).
*AV taramasi yapilan servislerden gereksiz olanlari iptal edin..(HTTP, FTP, SMTP, POP, IMAP)(Firewall > Protection Profile).
* Oversized file degerlerini devre disi birakin veya küçültün. (Anti-Virus > Config > Config).
*DHCP server’i devre disi birakin.. (System > DHCP > Service and System > DHCP > Server).
* DNS Forwarding özelligini devre disi birakin. (System > Network> DNS).
*IPS kontrolünü devre disi birakin. IPS > Signature and IPS >Anomaly).
*Default oturum süresini minumum deger olan 300 e çekin.Böylece hafizada oturumlar maximum 300 saniye tutulkacaktir.
config system session-ttl
set default 300
end
* Fortiguard servislerine ait cache sürelerini düsürün. Default 3600 dür.
config system fortiguard
set webfilter-cache-ttl 500
set antispam-cache-ttl 500
end
* DNS cache süresini azaltin:
config system dns
set dns-cache-limit 300
end
* DNS forwarding özelligini devre disi birakin( Yalniz 50,60 ve 100 modellerinde):
config system dns
unset fwdintf
end
