Cisco 1841 – 充当 PPPoE 终端器?

Cisco 1841 – 充当 PPPoE 终端器?

我们有 2 个 Fortigate 200B 防火墙,希望它们在 Active/Active HA 模式下运行 - 但显然,它们无法在外部接口上启用 PPPoE/DHCP 来执行此操作。

为了解决这个问题,我们想使用 Cisco 1841 作为其f0/1接口上的 PPPoE 终端,并在其接口上显示静态 IP f0/0(我们对 Cisco 857 盒进行了类似操作,以终止 RJ11 ADSL PPPoE 连接,并在 200B 的 RJ45 FE 接口上转发)。这将使我们能够将两个 200B 设置为手动,并向它们分配公共 IP 地址。

一般理论是:

f0/0取消对具有PPPoE虚拟接口的LAN侧的静态路由地址的编号Dialer1

因此,我们在 Cisco 857 上有这个配置(可以工作):

!Internally facing

interface Ethernet0
 ip address [ip.add.ress.here] 255.255.255.248
 ip virtual-reassembly
 ip tcp adjust-mss 1452
 hold-queue 100 out

!Externally facing ADSL connection

interface ATM0
 no ip address
 atm vc-per-vp 64
 no atm ilmi-keepalive
 dsl operating-mode auto
 pvc 8/35 
  no oam-pvc manage
  pppoe-client dial-pool-number 1

!Virtual PPPoE interface

interface Dialer1
 ip unnumbered Ethernet0
 ip virtual-reassembly
  encapsulation ppp
 ip tcp adjust-mss 1452
 dialer pool 1
 dialer-group 1
 ppp authentication chap pap callin
 ppp chap hostname [our username]
 ppp chap password 7 [our password]
 ppp pap sent-username [our username] password 7 [our password]
!
ip route 0.0.0.0 0.0.0.0 Dialer1

在我们的 1841 上,我们有这个:

! Internally Facing

interface FastEthernet0/0
 ip address [ip.add.ress.here] 255.255.255.248
 ip nat inside
 speed 100
 full-duplex

! Externally Facing

interface FastEthernet0/1
 no ip address
 speed 100
 full-duplex
 pppoe enable group global
 pppoe-client dial-pool-number 1

! Virtual PPPoE Interface

interface Dialer1
 mtu 1492
 ip unnumbered FastEthernet0/0
 ip nat outside
 ip virtual-reassembly in
 encapsulation ppp
 dialer pool 1
 dialer idle-timeout 0
 dialer-group 1
 ppp authentication chap pap callin
 ppp chap hostname [our username]
 ppp chap password 0 [our password]
 ppp pap sent-username [our username] password 0 [our password]
 no cdp enable
!
no ip classless
ip forward-protocol nd
!
ip route 0.0.0.0 0.0.0.0 Dialer1
!
dialer-list 1 protocol ip permit

但是我们似乎对这个配置不太满意,有人可以提供建议吗?
