I happened to come across this today and remembered the details.
In your specific Linux server(s), create the following file (and parent directories if needed)
/etc/WebObjects/Properties
BTW, this is referred to as the 'Machine Properties' file in ERXProperties. Every Wonder app will read this file when it exists on a host. it is useful for host-specific properties, which is exactly what IP addresses are.
In that Properties file you can define an array property containing the multiple IP addresses that your host has assigned to its network interfaces, for example on one of our servers, that Properties file has the following contents:
admin@silicon /etc/WebObjects: cat Properties
# Used by Wonder's WOHostUtilities to solve wo app local ip discovery on multihomed linux machines
er.extensions.WOHostUtilities.localhostips=(192.168.3.168,192.168.1.168)
Hope that helps,
Kieran
