I've partially answered my own questions but I have new ones. After
reading up on the topic I discovered that IP aliasing has been
deprecated together with ifconfig, and the preferred way for controlling
interfaces and routes is using iproute/iproute2. Apologies to those who
think this is newbie stuff--I feel I'm still living in the ipfwadm and
ipchains era. Iproute allows multiple addresses on one device without
using the old eth0:n (aliasing) way of assigning things. Unfortunately
it seems that /etc/network/interfaces does not allow multiple addresses
without using aliasing. Does anyone know how to assign multiple IP
addresses on Debian/Ubuntu using /etc/network/interfaces without
aliasing?
Thanks.

Subject: [SLUG] IP Aliasing
I've read from a long time ago (during the time of Linux 2.2.x)
that the practice of IP aliasing is not recommended for commercial use.
Our network has a Linux box hosting 2 public IPs and does various
routing tasks. It has 4 network cards already, connecting different
subnets of the office and another Linux router where our hosted client
servers are. I have configured this new firewall from scratch to replace
the old dodgy FC1 firewall of an ex-employee. Are there any gotchas to
using IP aliasing (eth0, eth0:0, eth0:1, ...) in a commercial
environment? What is everyone else doing?
Our 2 IPs are used to host various smtp, http and https
services. It should be possible to run different http/https services on
different ports and have linux forward them but the management doesn't
want their clients to be typing port numbers in URLs.
