Hi,
Lets go back a step. What happens if you statically set your network
settings on a random "hanging" PC?
E.g.
Lets assume your current network is something like:
192.168.1.1 <-- Smoothwall gateway/dhcp/dns thingy
It dishes out IPs from lets say 192.168.1.100 - 192.168.1.200
In that IP it will set the gateway/dns to 192.168.1.1
Lets assume our test PC is 192.168.1.101.
Statically set:
IP: 192.168.1.101
Netmask: 255.255.255.0
Gateway: 192.168.1.1
DNS: 127.0.0.1
Under linux open up /etc/hosts. On Windows, run notepad as admin and
open up c:\windows\system32\drivers\etc
Either Linux or Windows, this is the same. The Format is to just add a
line for every IP you normally resolve:
E.g.
192.168.1.10 fileserver
192.168.1.20 webserver
192.168.1.30 rivendell
Save the file and quit.
You will have to disconnect and reconnect your network to pick up the
changes (I think Windows will change when you press OK on the network
properties box). Linux you can do the usual sudo ifdown eth0 && sudo
ifup eth0.
Then try pinging fileserver etc. It will use the local hosts file for
DNS so you shouldn't have any slow down unless you have mapped/mounted
drives that resolve with server names.
If so make sure you add that server name to the hosts file.
Finally, I don't think this will be the case but if you have set up
VLANs it may be that your file wall is responsible for routing between
VLANs so this could be where your problem lies.
FYI Firewalls, pfsense.org, its brilliant. Its BSD based but the web
interface is easy to understand, it can run off a USB stick and use your
spinning disks for web caching. I've been using it for 5 or 6 years and
its rock solid. It can also do VPNs, VLANs, proxying, logging, AV
scanning, failover (if you have more than one box or one box with more
than one internet connection).

tried ipfire no success went back to smoothwall one.
everything to auto only no gateways etc and wired network is fine as
long as isp modem is on.
turn it off and just hangs waiting for some timeout it appears.
Also if I connect a wlan0 to a wireless router using a different isp
modem and turn both wlan0 and eth0 on doesn't know where to find inet
so hangs up. would have thot OS would check both and use first one
that comes back with a live and/or fastest connection automatically.

yup, I use ipfire (studio in green zone) in a rather similar setup,
no problem at all when ISP or ISP modem is down

There's your hangup !
Everything is not hung, but is waiting for a DNS time-out.
