I have a FreeBSD 5.3 workstation connected to the net via user-ppp with a dynamic IP. I have user-ppp doing both NAT and simple firewall.
I have a headless server box, also 5.3, set up as a NAT client. I run it only when I need the horsepower since it's loud and sucks power.
My problem is that the NAT client acts funny. It makes the gateway/workstation box dial up when I attempt to automount from it for example. Also I've had troubles with ssh delays. I'm pretty sure that what is happening is that it wants to use DNS to resolve names sometime even though all that it needs _should_ be in the /etc/hosts file (and nsswitch.conf lists files first.)
On the NAT client, I have my defaultrouter set to the NAT server's IP (in the 172.16 range.) Also I have my ISP's dns server in /etc/resolv.conf. I can't seem to make things work well any other way.
Can someone recommend a better setup to aviod my problems, or suggest that I should _not_ be having these problems with this setup and that something else in my setup must be wrong?
A long, long time ago, I set up a caching-only DNS server on a gateway box 'for the fun of it.' If there is not a simpler solution, I'll do it again (though the fun has worn off), but I thought I'de ask here first.
BTW, I have done some research on this, but really didn't find that many specific details about NAT client configuration...possibly I just didn't look hard enough.
Maybe you are searching for the wrong keywords. I simply haven't heard of anyone speak of a "NAT client" or "NAT Server" before.
Secondly you haven't told us anything about how things are setup: Are you using ipfw, ipf or pf? What are your nat-rules? what are your filter rules?
You are trying to automount what? nfs, smbfs?
ssh delays? did you try to type in the ip to see if it was faster?
I think I get the picture of your network but sometimes it helps a lot if you scetch the network with a ascii-diagram, add ip's etc.
Cheers, Erik
