Wlan questions... cisco 350-series.

[Jkh]

Hi, I´m thinking of using linux server to connect to my ISP, because i have to use a external antenna(it's a wlan connection). I have a cisco 350-series pcmcia card + pci card. Now I got a used box from work (P3 933Mhz, 256mb , 40G hdd) and the idea is to use this as a gentoo server. I have ordered a zyxel prestige 340WT and a zyxel 162-pcmcia card aswell. The zyxel pcmcia card is for my laptop(running Xp), the prestige 340WT is for a internal wlan at home. The gentoo server would be connected to the prestige over ethernet.
Now i would some info how to setup the gentoo box to access the isp and get it to forward inet traffic to the prestige. Do i have to bridge the connections or what would bee the proper way of doing this?
