思科防火墙的基本配置思路如下:
1. 配置管理口IP地址及默认网关
2. 配置内部接口IP地址及开启NAT转换
3. 配置外部接口IP地址及开启NAT转换
4. 配置访问控制列表(ACL)并应用到接口上
5. 配置静态路由
以下是一些常用的命令:
1. 配置管理口IP地址及默认网关:
```
configure terminal
interface management 0/0
ip address <ip_address> <subnet_mask>
exit
ip default-gateway <default_gateway>
exit
```
2. 配置内部接口IP地址及开启NAT转换:
```
configure terminal
interface GigabitEthernet 0/1
ip address <ip_address> <subnet_mask>
ip nat inside
exit
ip nat inside source list <acl_name> interface GigabitEthernet0/0 overload
exit
```
3. 配置外部接口IP地址及开启NAT转换:
```
configure terminal
interface GigabitEthernet 0/0
ip address <ip_address> <subnet_mask>
ip nat outside
exit
```
4. 配置访问控制列表(ACL)并应用到接口上:
```
configure terminal
access-list <acl_name> permit <source_ip> <destination_ip> <protocol>
interface GigabitEthernet0/1
ip access-group <acl_name> in
exit
```
5. 配置静态路由:
```
configure terminal
ip route <destination_network> <subnet_mask> <next_hop_ip_address>
exit
```
