Question Virtualbox guest as a firewall for lUbuntu host

Using virtualbox, I am trying to use Alpine linux (guest) as a firewall for my lubuntu (host). My physical network card (NIC) is eth0.

ISP WAN -> Alpine linux (guest) -> lubuntu (host) LAN

I am trying to get the ip from my ISP DHCP server but I had no success. I know that in virtualbox I have to use bridged adapter in eth0.
But in AlpineLinux (guest) do I have to create a vlan? Thats where I get confused.

ISP WAN -> DHCP -> Alpine linux (guest)

I was able to do this with two PCs like this:

ISP WAN --> Alpine linux firewall (PC1) --> Lubuntu LAN (PC2)

But now I am trying to do it with just one PC using virtualbox like this:

ISP WAN --> Alpine linux firewall (PC1) (Guest) --> Lubuntu LAN (PC1) (Host)

pbuilder-uml.conf - configuration file for user-mode-linux port of pbuilder DESCRIPTION
/etc/pbuilder/pbuilder-uml.conf contains default values used in pbuilder-user-mode-linux program invocation. FORMAT
MY_ETH0=tuntap,,, Configures ethernet setting used for booting linux. See how rootstrap boots your system, and copy that. Specify --eth0=slirp,12345,/usr/bin/slirp-fullbolt to use the slirp connection. UML_IP= IP address to use for guest OS. This can be set to dhcp for obtaining IP address through DHCP. UML_NETMASK= Guest OS netmask UML_NETWORK= Guest OS network UML_BROADCAST= Guest OS broadcast UML_GATEWAY= Guest OS gateway PBUILDER_UML_IMAGE=${HOME}/uml-image Guest OS file system image. UML_MOUNT_TMPFS=no Whether to mount tmpfs inside the guest image. This is probably mostly useless. BUILDPLACE=${HOME}/tmp/ The location which build will take place. pbuilder-user-mode-linux will place temporary COW files to there. The user running UML needs to be able to access that directory. UML_MEM=128 The amount of memory allowed for UML. Give more value to here. UML_HOSTNAME=uml-host The hostname for the UML. The hostname should be available in /etc/hosts so that hostname -f will be able to return the FQDN. UML_BUILDRESULT=/directory/of/build/result The directory where build result of pbuilder-user-mode-linux is stored. ROOTSTRAP_IMAGESIZE=size-in-megabytes The size, in MB, of the disk iamge to create. Defaults to 1000. NOTES
It is advised to set APTCACHEHARDLINK to no in ~/.pbuilderrc. see pbuilderrc(5) for details. AUTHOR
