PIX 515 with smtp

[logintck]

Dear

I am beginner of PIX

I set up a network

Internet ----PIX--- mailserver and DNS

And I run the following command

conduit permit udp DNS eq 53 any

conduit permit udp mailserver eq smtp any

I can resolve the MX and IP of mailserver in internet zone.

When I send mail to mailserver from internet, it can't delivery.

So I telnet mailserver with port smtp

The connection is ok but after 1 second the connection is dropped.

DO u have any idea of this problem

Thank you

Check your config against:

The turn on logging to troubleshoot with:

logging buffered debugging, then do a show log to

see who is sending the reset. You might want to do

a clear log before doing the tests.

conduit permit udp mailserver eq smtp any

should be:

conduit permit tcp mailserver eq smtp any

smtp is over TCP. hope this helps

SMTP uses TCP ...
