Hi:
I'm having problems with my dns setup on a FreeBSD network. I have a
one registered address (X.X.X.X) for the internet so I pipe all of my
contact with the net through a FreeBSD machine serving as a
"firewall"/proxy server. For the rest of my addresses I'm using the
class C specified in RFC 1597 for non-connected networks. On the proxy
server I run iijppp in auto mode so whenever a packet needs to be
routed to the real net it goes through my firewall. This all works
great. The problem is that when I go to rlogin to the proxy server it
insists sending a DNS packet to the net. This means dialing the phone
even though the host I'm trying to contact is on my side of the
"firewall". It also has to dial when it sends the nightly system
status mail to me at 0200. Here's some more details:
I'm running DNS on an internal machine as primary server for my
domain. Outside requests are forwarded to the proxy server.
I'm running a secondary DNS server on the proxy server. Outside
requests on this machine are forwarded to my ISP.
If it makes a difference I'm running the TIS firewall toolkit
proxys.
Name lookups for my internal machines done through nslookup
resolve quickly and correctly. E.g. nslookup 192.16x.xxx.2
returns my host yavin. and nslookup yavin returns 192.16x.xxx.2.
My internal domain name is vindaloo.com. This is a registered
domain (to me) but for the outside world it's only got an MX
record.
Any place I should start looking?
Chris
