configurin my network

[anarsipur]

i have a linux box runnin distro fc3.. i have three network interface cards on it..one i use for a download limited internet connection and the other for an unlimited download connection.. the third i use for sharin my internet connection(proxy).. which goes to the hub from where my other comps connect to the net.. so individually all the cards work fine.. but when i bring them all up together my internet connection stops workin..
so is there a order in which i have to bring them up??

Could be any number of things. Post your ifconfig -a output after it stops working. Perhaps it's an IP conflict.
