DNS Doctoring

    Is there any way of disabling the DNS doctoring of the Pix (v 6.3). We've
    just put one in on our network and created a static NAT mapping for the mail
    server. If we query any DNS server on the internet from within the network
    it shows as the internal address and so for a while we thought that the DNS
    had gone screwy! Now it seems apparent that the Pix is intercepting the DNS
    replies and changing them to the internal address.

    However, there is no DNS fixup and no alias command configured and so now I
    can't work out how to disable this feature.

    Any ideas anyone?

    Chris.

    6.3.1? There was a bug in 6.3.1 -or- 6.3.2 that did this exact thing.
    Upgrade to 6.3.3.

    Yup, 6.3(1). Thanks for that. I'll upgrade on Monday.

    Much appreciated Rick.
