Obviously when you buy those closed boxes, you get what’s lent and it does what the vendor wants it to do. But with DNS, you have the option to filter the DNS packets at the firewall and re-direct them to the internal DNS server. But you also have to arrange for the replies to get re-written as well so the devices sees the replies as having come back from the same address it sent the query to. Fundamentally this needs the traffic to pass through the firewall in both directions - either because the firewall is in the traffic path, or because it’s the default router for the DNS server. There’s a lot of stuff in the Shorewall FAQs, though I guess they “lose a bit in translation” if you aren’t familiar with Shorewall and it’s config files. https://shorewall.org/FAQ.htm#faq1f Simon _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
