Using Raspberry PI 4 B Wifi with 2 IP Addresses

Question

I need to setup my RPI 4 to use Wi-Fi but with 2 IP addresses, one from DHCP and the other one static, can someone please help I am not sure how to do this, as I need to put this configuration in the DHCPCD.conf file, we are not use the network manager in this case.

Thanks

Why? This is not technically impossible but not using dhcpcd and frankly there is no point. — Milliways, Feb 07 '22 at 08:53
OK for us, we need it. In the Hospitality Industry you will get info from one vlan while other vlan provide internet access. so if not possible via dhcpcd then how? — EnricoMTB77, Feb 07 '22 at 09:31
of course it's possible - it's fiddly with dhcpcd though (at least it used to be about 3 years ago) - best to switch to using NetworkManager - then it's really simple — Bravo, Feb 07 '22 at 09:39
Please explain how I must do it, so the Pi must still pickup a wifi ip from DHCP then also have the other static ip configured? — EnricoMTB77, Feb 07 '22 at 11:11
I have tried leaving the ipv4 ip setup blank, and then just added a router ip for extra ip but it does not work — EnricoMTB77, Feb 07 '22 at 11:15
done b4 with multiple static. never with dhcp plus static, but indeed theoretically possible so I'll certainly look forward to an answer, preferably one without a virtual network adapter. — Abel, Feb 08 '22 at 03:11
It may be easier to assign two IP addresses to two devices. For example, one to the WiFi adapter and another to the Ethernet adapter. — user68186, Feb 08 '22 at 21:19
yes, but they dont have ethernet at the location, if I assign 2 static ip's on wifi, do I add them in the same place in network manager or must the 2nd ip be somewhere els? — EnricoMTB77, Feb 10 '22 at 06:43
Does this answer your question? Set multiple static ip in dhcpcd.conf - Raspbian 8 (jessie) — user68186, Feb 12 '22 at 17:17

To make a Raspberry Pi wireless bridge you will need a USB WiFi adapter. Check out the following links to see if these will help you build what you are looking for.

I haven't tested these myself so suggest building a wired Ethernet to WiFi Ethernet bridge using eth0 and wlan0 on the raspberry Pi. If that works then upgrade by adding a USB wireless adapter, and change eht0 to wlan1 or what ever the wireless adapter appears as.
