Getting errors after adding a static/conduit for internal ftp server

Hi all,

I added the following two commands to the PIX and outside users were subsequently able to connect to the internal FTP server ( However, the syslog started to fill up with errors.

I am only using one global public address which is the PIX outside interface address ( for everything.

Here are the two commands I added:

static (inside, outside)

conduit permit tcp host eq ftp any

As soon as I did that, users could connect to but the IPSec and PPTP VPN connection attempts started to be rejected and the following errors accumulated in syslog:

Local4.Error %PIX-3-305006: portmap translation creation failed for tcp src inside: dst outside:

Local4.Critical %PIX-2-106006: Deny inbound UDP from to on interface outside

Local4.Critical %PIX-2-106001: Inbound TCP connection denied from zzz.zzz.zzz.55/22258 to flags SYN on interface outside

I since removed the static and conduit entries and all is back to normal but no FTP... help!

Re: Getting errors after adding a static/conduit for internal ft

It seems to me that your problem is the fact that your doing a full static IP translation when you should use port redirection.If you have PIX Firewall Software version 6.0 or higher, you can use the port redirection feature.

The command syntax is as follows:

static [(internal_if_name, external_if_name)] {tcp|udp} {global_ip|interface}

global_port local_ip local_port [netmask mask] [max_conns [emb_limit [norandomseq]]]

In your case you should do something like this:

static (inside,outside) tcp interface ftp ftp netmask

conduit permit tcp host eq ftp any

I have not tested this feature, but it should work since the translation will exist only for ftp and it should not have impact on your IPSec connections.

Thank you so much! Now I understand, and it worked like a charm.
