Connection Sharing

[starmonche]

i have 3 boxes connected directly to my router. one is a slack box with two ethernet cards that has an xp box connected with a crossover. the xp box behind my slack box has internet access but cannot see the other comps on my lan (and vice-versa). i suppose i could connect a hub to my router and plug said xp and slack boxes into it but i'd like to get my setup working fully as is. any suggestions?

umm..
You said you are unable to see other computer on xp box.. b'coz that is on another LAN
to see other box in that you have to do bridging !
That can be done on Slackware box.

for bridgin there are few methods available.. do a search on google.com/linux

Ah, so "bridge" is the word I was looking for. I read up on it and it makes sense. One thing I left out, though, is that my Slack box is a webserver and the documentation I'm reading seems to be saying that my slack box will simply connect the two networks together by "giving" one NIC card to each network. Is this getting too sloppy?

i hate googling for something and finding a forum discussing my problem without it listing a solution:

--------------------------------
brctl addbr bridgename
brctl addif bridgename eth0
brctl addif bridgename eth1
ifconfig eth0 0.0.0.0
ifconfig eth1 0.0.0.0
ifconfig bridgename [ip address] netmask 255.255.255.0 up

]
--------------------------------

this works and both my xp box and slack box have 'net and lan access.

only remaining issue is that i'm unable to see the web site on my slack box unless i navigate to its local ip. (my router fwds port 80 to the slack box and it works fine if i undo the bridge).

sorry for the flood...i figured it out:

route add default gw x.x.x.x bridgename

where x.x.x.x is your router's ip
