思科路由怎么配置PIX虛擬防火墻
思科cisco依靠自身的技術(shù)和對(duì)網(wǎng)絡(luò)經(jīng)濟(jì)模式的深刻理解,使他成為了網(wǎng)絡(luò)應(yīng)用的成功實(shí)踐者之一,其出產(chǎn)的路由設(shè)備也是世界一流,那么你知道思科路由怎么配置PIX虛擬防火墻嗎?下面是學(xué)習(xí)啦小編整理的一些關(guān)于思科路由怎么配置PIX虛擬防火墻的相關(guān)資料,供你參考。
思科路由配置PIX虛擬防火墻的案例:
拓?fù)鋱D
這個(gè)拓?fù)渲?,中間的PIX配置三個(gè)虛擬防火墻,Ethernet0連接到一個(gè)3550交換機(jī)的TRUNK端口,分別接到三個(gè)不同的VLAN,外口Ethernet1連接到Internet,試驗(yàn)中可以使用一臺(tái)路由器代替。
由于這里Ethernet0是和交換機(jī)的TRUNK端口相連,來接收不同VLAN的流量,所以這里使用子接口為TRUNK去VLAN標(biāo)簽,并將這些子接口分配給各個(gè)虛擬防火墻,是內(nèi)部各個(gè)VLAN都能訪問Internet
首先配置3550交換機(jī):
interface FastEthernet0/2
switchport access vlan 2
!
interface FastEthernet0/3
switchport access vlan 3
!
interface FastEthernet0/4
switchport access vlan 4
!
interface FastEthernet0/10 //和PIX的Ethernet0口相連
switchport trunk encapsulation dot1q //PIX的默認(rèn)的TRUNK類型就是dot1q
switchport trunk allowed vlan 2,3,4
switchport mode trunk
PIX的配置:
changeto system:
interface Ethernet0
!
interface Ethernet0.2
vlan 2 //為子接口進(jìn)行封裝,去VLAN標(biāo)簽
interface Ethernet0.3
vlan 3
interface Ethernet0.4
vlan 4
!
interface Ethernet1
!
admin-context admin
context admin
allocate-interface Ethernet0.2 Intf1 //分配E0.2子接口到虛擬防火墻admin,別名是Intf1
allocate-interface Ethernet1 Intf0 //分配接口E1到虛擬防火墻admin,別名是Intf0
config-url flash:/admin.cfg
!
context DepartmentA
allocate-interface Ethernet0.3 Intf1
allocate-interface Ethernet1 Intf0
config-url flash:/DepartmentA.cfg
!
context DepartmentB
allocate-interface Ethernet0.4 Intf1
allocate-interface Ethernet1 Intf0
config-url flash:/DepartmentB.cfg
changeto context admin:
interface Intf1
nameif inside
security-level 100
ip address 192.168.2.1 255.255.255.0
!
interface Intf0
mac-address 00aa.0000.01c1
nameif outside
security-level 0
ip address 192.168.1.10 255.255.255.0
changeto context DepartmentA:
interface Intf1
nameif inside
security-level 100
ip address 192.168.3.1 255.255.255.0
!
interface Intf0
mac-address 00aa.0000.01c2
nameif outside
security-level 0
ip address 192.168.1.11 255.255.255.0
changeto context DepartmentB:
interface Intf1
nameif inside
security-level 100
ip address 192.168.4.1 255.255.255.0
!
interface Intf0
mac-address 00aa.0000.01c3
nameif outside
security-level 0
ip address 192.168.1.12 255.255.255.0
最后在試驗(yàn)中代替Internet的路由器上進(jìn)行驗(yàn)證:
成功ping通每個(gè)虛擬接口上配置的IP地址。
