Hi
I am trying to configure cisco Pix firewall but not sure if the firewall is faulty or I am missing something I started with interface configs and i am not able to give IP to the interface
pixfirewall(config)# int ethernet 1
pixfirewall(config-if)# int ethernet 1.100
pixfirewall(config-subif)# ip add
pixfirewall(config-subif)# ip address 193.168.1.1 255.255.255.252
pixfirewall(config-subif)# no shut
pixfirewall(config-subif)#
pixfirewall#sh int ip brief
Interface IP-Address OK? Method Status Protocol
Ethernet0 unassigned YES unset administratively down down
Ethernet1 unassigned YES unset up up
Ethernet1.100 unassigned YES manual up up
Ethernet2 unassigned YES unset up up
Ethernet3 unassigned YES unset administratively down down

pixfirewall# ping 193.168.1.1

Hi Anuj,
You would need to assign the nameif to the interface as well:
pixfirewall(config)# int ethernet 1
pixfirewall(config)# no shut
pixfirewall(config-if)# int ethernet 1.100
pixfirewall(config-subif)# ip add
pixfirewall(config-subif)# ip address 193.168.1.1 255.255.255.252
pixfirewall(config-subif)#nameif inside (just an example for name)
pixfirewall(config-subif)# no shut
Hope that helps,
Thanks,

I just want to assign the IP addresses to the interfaces. Pref. without sub interfaces
tried giving the names as well but still not showing the ip address
pixfirewall(config-if)# int Ethernet1.100
pixfirewall(config-subif)# name
pixfirewall(config-subif)# nameif inside

Hi Anuj,
Try changing the firewall mode to routed mode so that you can assign ip address to the interfaces directly. I hope that is in transparent mode so it asks for the vlans to be configured for the IP assignments.
Pls check and revert back.
Please do rate if the given information helps.

To avoid the message ERROR: VLAN must be configured for interface Ethernet1.100, try to configure the vlan before:
pixfirewall(config-if)# int Ethernet1.100
pixfirewall(config-subif)# vlan 100
...
It works on GNS3, so it's easy to solve.

Hi Anuj,
The reason why you can't configure anything on the PIX is because that particular PIX has "
Failover Only-Active/Standby (FO) license", meaning you can't configure it as a standalone PIX.
This PIX needs to be part of an Active/Standby failover PIX pair, and the configuration needs to be synchronised from the Active Primary PIX to this PIX.
Hope that answers your question why it's not configurable.
