Hi, everyone! Today I’m going to introduce the L3 Virtual firewall - in 5 easy steps. Eudemon200E-X V300R001
1. Create virtual firewall vf1
[Eudemon] ip vpn-instance vf1
[Eudemon-vpn-vf1] route-distinguisher 100:1
[Eudemon-vpn-vf1]quit
2. Bind inside interfaces and outside interface to virtual firewall
[Eudemon]interface gi0/0/0
[Eudemon-GigabitEthernet0/0/0]ip binding vpn-instance vf1 \\ bind interface to virtual firewall first and then assign ip address
[Eudemon-GigabitEthernet0/0/0]ip add 192.168.1.1 24
[Eudemon-GigabitEthernet0/0/0]q
[Eudemon]interface gi0/0/1
[Eudemon-GigabitEthernet0/0/1]ip binding vpn-instance vf1
[Eudemon-GigabitEthernet0/0/1]ip add 1.1.1.1 24
[Eudemon-GigabitEthernet0/0/1]q
3. Add interfaces to the security zones of virtual firewall vf1
[Eudemon]firewall zone vpn-instance vf1 trust
[Eudemon-zone-trust-vf1]add interface giga0/0/0
[Eudemon-zone-trust-vf1]q
[Eudemon]firewall zone vpn-instance vf1 untrust
[Eudemon-zone-untrust-vf1]add interface giga0/0/1
[Eudemon-zone-untrust-vf1]q
4. Configure interzone filtering for vf1 to allow packets from trust zone to pass to untrust zone.
[Eudemon]policy interzone vpn-instance vf1 trust untrust outbound
[Eudemon-policy-interzone-trust-untrust-vf1-outbound]policy 0
[Eudemon-policy-interzone-trust-untrust-vf1-outbound-0]policy source 192.168.1.0 0.0.0.255
[Eudemon-policy-interzone-trust-untrust-vf1-outbound-0]action permit
[Eudemon-policy-interzone-trust-untrust-vf1-outbound-0]q
[Eudemon-policy-interzone-trust-untrust-vf1-outbound]q
5.Configure NAT outbound to permit trust zone users to access untrust zone using 1.1.1.2 to 1.1.1.4 address
[Eudemon]nat adress-group 1 1.1.1.2 1.1.1.4 vpn-instance vf1
[Eudemon]nat-policy interzone vpn-instance vf1 trust untrust outbound
[Eudemon-nat-policy-interzone-trust-untrust-vf1-outbound]policy 0
[Eudemon-nat-policy-interzone-trust-untrust-vf1-outbound-0]policy source 192.16.1.0 0.0.0.255
[Eudemon-nat-policy-interzone-trust-untrust-vf1-outbound-0]action source-nat
[Eudemon-nat-policy-interzone-trust-untrust-vf1-outbound-0]address-group 1
[Eudemon-nat-policy-interzone-trust-untrust-vf1-outbound-0]q
[Eudemon-nat-policy-interzone-trust-untrust-vf1-outbound]q
