at my workplace there is intranet that we use to access our local site to do office work.
occassionaly we use smartphone as modem to connect to internet to access. but when we try to access a site on internet it displays page not found. Then for this we have to temporarily disable the wired intranet. Then to access the intranet we have disable the wireless modem and enable intranet. is there any way that both connections are active simultaneously and whenever we type some address it should first check local intranet and if found load it else access the internet to load website?
