Sounds ideal to me. Are you running any firewall setup on the laptop?
something I have upgraded, I suppose. hosts.allow has all the usual
entries, I can ping out to the network, and send mail normally through
my firewall machine to the adsl router. Name serving seems to be
working, though I cannot check with dig as it is not installed on this
machine and I never did find what package provides it.
If this command returns a list of machines, your DNS setup is working:

Not being able to ping your box can be annoying when you're trying to
diagnose connectivity probs. What does this produce:
iptables -L

Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Dolphin:~#
It seems to me you have an unexpectedly secure firewall setup:-)
