Robert,

Your conduit command doesn't look right.  Typically you want to allow any
outside host to access the inside host specified in the conduit.  You can
specify 'any' by using 0.0.0.0 or 0:


conduit (inside,outside) xxx.yyy.115.172 25 tcp 0 0

Also, I'm not sure what your trying to accomplish with those alias commands:

alias (inside) 172.20.21.241 xxx.yyy.115.190 255.255.255.255

Your telling the PIX to translate dst address 172.20.21.241 to
xxx.yyy.115.190, which in turn has a static to translate xxx.yyy.115.190
back to the same inside address?  Typically the internal hosts would just go
directly to the 172.20.21.241 address without having to go through the PIX
in the first place.

HTH,
Kent

Subject: Cisco PIX question, static, conduit, and alias [7:40722]


I am having a problem getting to the inside Mail/Web servers from the
outside and I can't determine why.

I'm replacing an old Cisco 7000 router with a new 7206 VXR.  I'm also
reconfiguring the way their PIX was setup.  The servers were configured
with outside addresses (the PIX had a 'nat 0 xxx.yyy.115.0' statement)
which made them vulnerable.  I am moving them to an inside address and
building a conduit from the outside to the inside.

In order to leave their old network up and running while I configured the
7206VXR.  I used my PIX 506 (Ver 5.x) for configuration purposes.  I had
everything configured and working.  Then over the Easter holiday I
configured their PIX trying to use the same statements that I had in my PIX
506.  This is where I ran into problems.  Since they are running such an
old version (Ver 4.1.4) of the IOS I could not use the same exact
commands.  I'm not as familiar with the PIX 4.1.4 commands and obviously
have something stated incorrectly.  Below I have what I believe to be the
pertinent information from both the 7206 and PIX.  Can someone tell me
where I went wrong.  The xxx.yyy represent the same 2 octets through out
both configs.  Any help greatly appreciated.

Cisco 7206 VXR
