                                                                ----nic2  ------- Office computer

why not add a 4th nic to your isa server and connect that nic to your wireless environment ?
or buy a router/layer3 switch that connects the office/wireless/dc network to your isa box...then you'll only need 2 nics in the isa box

Thanks bio for the reply. yes i tried adding 1 nic on the isa box but that was and old desktop unit. now we upgraded to newer intel destop board but limited pci slot. hmm we are limited in terms of hardware here.
i gues we have here a layer 3 switch ..DGS - 3612. i just dont know how to configure it. i can log in to the admin thru web. im having difficulties trying to set it on vlan. i hope you can help me..this what i want to achieve:

1.) external nic ...DHCP from our ISP (or ppoe dialer)
2.) internal network (nic1) 192.168.3.0 this is for severs and admin office                    3.) vlan( 192.168.1.0) -- this is for the public users and other ofices that hate proxies..
4.) 2nd network(nic2) --- wifi environment.. authenticate via isa proxy

i already implemented 1,2,4.. my problem is where to place #3.. i dont want to use router with NAT since i cant control them.

thanks..
