umm? you have 2 ISP connections ?

what software is running on the linksys? dd-wrt ? openwrt ? original linksys firm?

how is your network configuration ?

~~**salih**~~

your speedtuch is also router forword the port need it on your speedtuch and use
your router linksys as wireless bridge for other lan conexion your router can work like switch

you don`t need to use 2 router will not work

connect your speedtuch to your pc and go to dos command cmd and type ipconfig/all
you will get the default getway is your router ip

open your browser and type your router ip
go to advanced and than Nat and added port you need
whene you finsh to click on router save settings

Thanks for your answers.I have original linksys firm.My linksys is connected with speedtouch with ethrnet from port internet(in linksys).I tried to put both pc and dream in speedtouch but i can't connect to dream even with the right ip.If i use linksys as wireless bridge,my other pc on it which is wired connected will work?I didn't understand well.More help i will appreciate.
