The gateway is 192.168.73.1

My ask is I need both of these IPs reachable from outside.
Or
Either any one of these IP should be reachable from outside when I connected to wifi network as well as when connected to ethernet LAN network.

pbuilder-uml.conf

pbuilder-uml.conf(5)						     pbuilder						      pbuilder-uml.conf(5)

NAME

       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,,,192.168.0.2
	      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=192.168.0.3
	      IP address to use for guest OS.

	      This can be set to dhcp for obtaining IP address through DHCP.

       UML_NETMASK=255.255.255.0
	      Guest OS netmask

       UML_NETWORK=192.168.0.0
	      Guest OS network

       UML_BROADCAST=255.255.255.255
	      Guest OS broadcast

       UML_GATEWAY=192.168.0.1
	      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.
