Trouble is - I cant the clients to resolve hostnames to each other -
best I can do is ping the smoothwall box by name. I can ping the
clients from the others by IP.

I have got the gateway set up on each client pointing to the
smoothwall box. I have the smoothwall box set as the dns server on the
clients.

The clients connect fine to the internet over the firewall so I can
assume that DNS is working ok from the outside world via smoothwall.
for example I can ping www.yahoo.com from a client and get a correct
ip back. But not machines on the local network.

I'm guessing I've missed a configuration setting on either smoothwall
or the clients.

Could someone point me in the right direction - I have read the DHCP
mini howto and I cant see anything I've missed.

Thanks in advance.

Hi!,

Check to make sure that your smoothwall configuration is allowing packets
which contain your internal IP address to move between the various interfaces
that it uses (if there is more than one interface being used).

See ya

He said ping from one client to another works if he specifies the IP
address.  So this can't be it.

ok.

eh?.

ok.

This sounds like the DNS server doe snot have the LAN ip addresses.

host -l <domain> <nameserver ip>

ie if hostname is host.domain.com and DNS id at 192.168.1.1

host -l domain.com 192.16.1.1

DNS zone is probably missing entries.

Hi!,

Ahh, but ICMP might work, but does smoothwall configuration target UDP and TCP
packets separately ?

I am quite sure that smoothwall could still allow icmp packets to move between
the interfaces but reject TCP/UDP packets.

See ya
