sometimes you’ll get devices with builtin switches that only have one or two ethernet ports actually connected to the cpu, most soho routers are like that
Only if you had no control over the OS you can install on the device. Systems with preinstalled firmware/OS will generally have a setup already that sets whats LAN and whats WAN. Some software will allow for the control over the defaults and some wont. If you buy hardware with nothing on it or flash it with something else usually you set whats what.
I want to make my own router with linux OS or maybe pfsense , I’d put a vpn on it , control and reach my sftp server from any where securely , put APs in the house and connect them to it through ethernet and MAYBE later add another connection from my ISP .
that’s why I want to make my own router . put I want to know the answers to my questions about ports
just my two cents, if you have an older pc laying around just add a 4 ethernet port intel nic card to it and a cheap hard drive or ssd and 4 gb of ram. Configure Linux,BSD, what have you and work from there. Buy a nice managed switch and use vlans when you can.
actually yeah I know that but I have no old pc … and the prices now is too high to build a cheap one , that’s why I want a system build already . I’m still searching but if you have recommendation please tell me .
also how do you think an ARM based hardware will do ??
I found this …
yeah there is , but the prices is a little too high for what it is . they want about 40 ~ 50 US $ for a mother board and integrated 1 core celeron with nothing else .
that’s why I won’t buy it , I still need PSU RAM and storage
yeah it is 500 but I’m searching I wont buy this . I put it’s link for you to see the ports the sorted in 2 categories .
anyway I’ll buy the cheapest … I maybe buy some ARM based hardware … some of it is around 100 $ .
and don’t forget , this is new hardware … that is used and so old , let alone power usage and volume
