Where you used to do it in global config mode, 7.0.1 now has similar router commands to go into interface mode:
pixfirewall(config)#interface Ethernet0
pixfirewall(config-if)#speed 100
pixfirewall(config-if)#duplex full
pixfirewall(config-if)#nameif outside
pixfirewall(config-if)#security-level 0
pixfirewall(config-if)#ip address 192.168.9.30 255.255.255.0
pixfirewall(config-if)#exit
pixfirewall(config)#interface Ethernet1
pixfirewall(config-if)#speed 100
pixfirewall(config-if)#duplex full
pixfirewall(config-if)#nameif inside
pixfirewall(config-if)#security-level 100
pixfirewall(config-if)#ip address 10.0.0.1 255.255.255.0
pixfirewall(config-if)#exit
pixfirewall(config)#global (outside) 1 interface
pixfirewall(config)#nat (inside) 1 10.0.0.0 255.0.0.0
pixfirewall(config)#route outside 0.0.0.0 0.0.0.0 192.168.9.2 1
