next in thread | raw e-mail | index | archive | help
Just to set the scene,
I have a FreeBSD machine (firewall and isdn gateway to the net)
A Linux box (email etc, and a temporary dialup net connection)
A handfull of windows machines
all on a sub net 192.168.2.*, all on the same physical network
Every thing seems to work ok exept any form of connection between the
freebsd and linux box
I can ping the linux and freebsd from my win98 machine, I can ping my
machine from both freebsd and linux.
but I cant ping the linux box from freebsd or freebsd to linux, or connect
via telnet.
the ping just 'hangs' with no output (I have left it for about 10mins).
my machine is 192.168.2.6
freebsd .110 (blackhole)
linux .100 (sykes)
