I should have known better than _that_. OK, it works now. Thanks very
much.

Good point. I don't know how, or if, proxies like squid use persistent
connections. I suspect that some load-balancing schemes already break them.
apt-get (Debian's package downloader) already knows how to parallelize hosts.
It would be nice to parallelize the interfaces at the same time.
FYI, this is a picture of my net.
768K SDSL ------------------------------------ eth0
1.5M..384K/128K ADSL ------------------------- eth1
^
| (10MBPS)

Retail Router Box Linux Box
Serves local DHCP
hosts with DHCP, NAT,
"firewall", gateway.

Local DHCP net ------------------------------- eth2
All networks are 100/10 MBit full-duplex switches. Both DSL modems and
the uplink port of the retail router run 10 MBit half-duplex, everything
else runs 100 MBit full-duplex. Not much should be going through
the retail router box, as the Linux box serves the local net with squid,
IMAP, SMTP, and telnet. I could dispense with the router box and route
with Linux if I wanted to.
Attached is what I ended up with in /etc/network/interfaces:
Thanks
