## VXLAN IPSEC Encryption
## If you need to add encryption on top of a VXLAN, it’s possible to do so with IPSEC, through strongswan.
## You’ll need to reduce the MTU by 60 bytes (IPv4) or 80 bytes (IPv6) to handle encryption.
## So with default real 1500 MTU, you need to use a MTU of 1370 (1370 + 80 (IPSEC) + 50 (VXLAN) == 1500).
#apt install strongswan

##Suricata IPS integration
##If you want to use the Suricata IPS (Intrusion Prevention System), it’s possible.
##Packets will be forwarded to the IPS only after the firewall ACCEPTed them.
# apt install suricata
# modprobe nfnetlink_queue
