Item Portfolio

The task was complicated as i had to deal with data loss and partition damaged , on top of crashed vms. i had to mount images in live iso, to extract the data , and rebuild the entire vms that crashed again.
Crashed VMware vms
the client had problems with a mikrotik router, and ESXI server and a vm behind a vSwitch which was suppose to connect on TenGbp/s network. Then the second request was to limit the port on 4Gbp/s , particularly the interface that connected on ESXI server.
fix routes in mikrotik
Client had an infrastructure of Gaming servers behind the Mikrotik which was having issues from being DdoS every second with huge amount of packages above 10gbp/s. Normal firewalling would lead the mikrotik to reboot , since it was consuming way too much CPU. need to reimplement everything on prerouting / RAW and Mangle to have the mikrotik respond the expected way
Block DDos on Mikrotik
