Hello all,
I have an interesting problem. I have a small LAN based on ethernet with
a Linux box with a ppp connection to the internet acting as a gateway for
two Macintosh computers:
-------------------
| Linux | |---Powermac with OpenTransport
| | | 192.168.1.2
ppp | | eth0 |
-------| 192.168.1.1 |------------|
| | |
| | |---68K mac with MacTCP
------------------- 192.168.1.3
The linux box runs pppd/diald. This setup has worked flawlessly for a year
with a Slackware installation (kernel 1.2.13). I am now upgrading to
Debian 1.2 (kernel 2.0.27) and have run into frustrating problems.
After some hair pulling I have pppd/diald working on the new system.
I have compiled in kernel support for ip masquerade and set up the
forwarding with
ipfwadm -F -a m -S 192.168.1.0/24 -D 0.0.0.0/0
Now the problem:
**I can not do domain name resolution with my new setup** The ip masquerading
seems to work with most network traffic. Packets sent by IP number are
forwarded appropriately. I can telnet and use my web browser on my macs if
I use IP numbers. DNS resolution works great on the linux box, and I
have triple checked the nameserver addresses on the macs. When I do a name
lookup on the mac I can see the modem SD light periodicly lighting up,
so I assume that DNS queries are being sent, but now replys. I can do
a name lookup on the linux system without difficulty. The nameservers
on both machines are configured identically.
The kicker: booting with my old slackware setup fixes this problem,
without changing anything on the macs.
I have searched the FAQ's without avail, any pointers to info or ideas
to try would be much appreciated.
Thanks in advance,
Ben
