• 基本配置步骤
1. 用Null Modem(DTE—DTE)线连接Console口(9600-N-8-1)
2. 进入Enable,用enable(第一次口令为空)
3. 进入配置状态,用configure terminal
4. 配置Telnet和Enable口令 Telnet:passwd xxxxxxx
Enable: enable passwd xxxxxxx
5. 配置Hostname,用hostname pix
6. 配置Ethernet Interface interface ethernet outside auto(外部网卡类型)
interface ethernet inside auto(内部网卡类型) ip address inside 10.1.1.1 255.255.0.0(内部网卡IP) ip address outside 192.31.7.1 255.255.255.0(外部网卡IP)
7. 配置Global IP,用global 1 192.31.7.128-192.31.7.252
8. 配置NAT IP,用nat 1 10.1.0.0 255.255.0.
9. 配置Route
10. 限制Telnet到PIX的主机IP(只能是私有IP),用telnet 10.1.1.252 255.255.255.255
11. 保存配置,用write memory
12. 退出,用quit
• 可选配置
1. 配置SYSLOG syslog output 20.7 facility = Local4 (20) Level = debug (7)
no syslog console
syslog host 10.1.1.254
2. 配置Static IP及
对外Web服务 Static: static 192.31.7.254 10.1.1.254
conduit 192.31.7.254 80 tcp 0.0.0.0 0.0.0.0 (允许外部Host访问Web端口)
3. 配置Mailhost
Mailhost: mailhost 192.31.7.253 10.1.1.253
conduit 192.31.7.253 25 tcp 0.0.0.0 0.0.0.0 (允许外部Host访问SMTP端口)
4. 配置Aclearcase/" target="_blank" >ccess
Control
(缺省不配置)
outbound 10 deny 0.0.0.0 0.0.0.0 (deny所有Tcp访问)
outbound 10 permit 0.0.0.0 0.0.0.0 21 (permit所有Ftp访问)
outbound 10 permit 0.0.0.0 0.0.0.0 23 (permit所有Telnet访问)
outbound 10 permit 0.0.0.0 0.0.0.0 110 (permit所有POP3访问)
outbound 10 permit 10.1.1.253 255.255.255.255 25(permit该IP访问外部SMTP主机)
apply 10 outgoing_src (使Access Control生效,以源地址为控制对象)
