What do i need on this PIX to allow telnet traffic inbound?

Posted on 2011-05-11
Last Modified: 2012-05-11

I just set up my home network - i have a cisco pix 506E that's connected (via a static IP) to a cable modem.  Internally, all my clients connect to the PIX, which is providing DHCP, etc.
Internal network is /24.

PIX internal address is
PIX external address is, for argument's sake,

Two things i want to be able to do:  

1) I need to allow FTP traffic inbound to a certain IP address (  Over time, i'm going to need to allow certain other traffic types to different internal IPs (for instance I may need web traffic on port 80 to go to, etc).

I put the following commands in the PIX, but for some reason the computer i was on suddenly lost internet connection (bizarre, but from another computer on another internet connection i was able to access the FTP server!).  The commands were:

static (inside,outside) netmask 0 0
conduit permit tcp host eq ftp-data any
conduit permit tcp host eq ftp any

2) I need to be able to ping the PIX from outside, and be able to ping outside IPs from inside the network.  I haven't tested pinging the PIX from outside the network, but i do know that i'm unable to ping outside addresses from inside the network.

Thanks everyone for your help in advance! Much appreciated!
I'm including the PIX config...

    Just noticed i posted this to the Voice over IP section by mistake.

    Moderator - if you could, please delete this question from that zone - it belongs in the other two zones i selected - "network routers" and "networking hardware firewalls"

    Thanks - and sorry

    You need to do port statics and not the one-one that you attempted.
    >static (inside,outside) netmask 0 0

    static (inside,outside) tcp interface ftp ftp netmask
    static (inside,outside) tcp interface ftp-data ftp-data netmask
    static (inside,outside) tcp interface www www netmask

    Yes, use the keyword "interface" in the configuration for both statics and access list.

    Then, create an access-list instead of conduits:
    access-list outside_access_in permit icmp any any
    access-list outside_access_in permit tcp any interface outside eq ftp
    access-list outside_access_in permit tcp any interface outside eq ftp-data
    access-list outside_access_in permit tcp any interface outside eq www

    then apply the access-list
     access-group outside_access_in in interface outside

    And this entry is in the acl?
    access-list outside_access_in permit icmp any any

    May sound counter-intuitive, but try this:
     no access-group inside_access_in in interface inside

    actually i take it back; when i tested it last i was on a different connection - d'oh...

    working great.

    curious though, why would removing that access-group from the inside interface have fixed it?

    Why You Should Analyze Threat Actor TTPs

    After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

    Creating an OSPF network that automatically (dynamically) reroutes network traffic over other connections to prevent network downtime.
    In the world of WAN, QoS is a pretty important topic for most, if not all, networks. Some WAN technologies have QoS mechanisms built in, but others, such as some L2 WAN's, don't have QoS control in the provider cloud.
