Hi again,
Sorry, of cause the bridge has a different IP from the nntpcache - it
should read 192.168.0.3 in my drawing below!
Like this:
clients --- router --S------- bridge --- router --- internet
10.x.x.x | 192.168.0.3
nntpcache
192.168.0.2
("S" is a switch I forgot earlier)
Regards,
Kent B. Hansen
