 From the LAN?  I can see why a firewall would drop packets on the WAN 
(I've never agreed with the reasons, but it's arguable) but one that 
would do it on the LAN seems to be somewhat broken IMO.  The authors 
have probably been reading too much Gibson :p

I wonder if we should devise something in cvsdiag that could analyse the 
health of the network - timing DNS/RDNS lookups, checking the 
reachability of the default route, external connectivity etc.
