Hi Gang,
Is it normal for DNS lookups (which are UDP, right?) to not obey
routing tables? I have a machine on network "A" configured to route
through a router that sits between "A" and "B", and use the gateway on
"B" as its default. The "B" gateway also knows how to get packets to
machines on "A". With this setup, I can successfully ping random hosts
"out there", and traceroute indicates that packets are going along the
path I want them to.. but DNS lookups fail. I can ping the DNS servers
with no trouble; just can't (seem to) get an actual query through to
them. i.e. (yes, the client machine is windows... the router and
gateway are linux, though!)
C:\> ping 4.2.2.4

I'm at a loss.. Any suggestions?
Thanks,
