[font=Courier New]Okay, so much for my idea of having a different interface (preferably one with no IP address at all, but that's okay too) proxy-ARP in place of the Linksys RT31P2 so that the ISP's router still knows to send traffic to all of my 10 static IP addresses down my DSL circuit to the RT31P2 for routing in to my network...

Two problems:

1. I don't think that the second Linux box I set up for the purpose of performing the proxy-ARP'ing was answering the ARP requests. Actually, for some reason I don't even think it was seeing them. I can't explain that. The physical network layout is like this:

phone line carrying the DSL signal
Outer 10Mbit Ethernet HUB (not switch)
proxy-ARP Linux server Linksys RT31P2
.................................................firewall Linux server
........................various servers, workstations, &etc

(sorry for the awful ASCII art above; the font settings &etc in this BB don't seem to be working when I preview the post)

When I sniff on the one interface on the proxy-ARP Linux server, I never see any ARP requests for the other hosts on my network (e.g. various workstations), even after the ISP's ARP cache for those IP addresses has timed out and I try web browsing from one of those workstations and can't get anything - no DNS lookup results, no web pages, nothing. So, that's one mystery - why don't I see ARP requests from the ISP's router? There's no layer 2 filtering going on between the DSL modem and the proxy-ARP Linux server - just a repeater hub.

So, maybe the proxy-ARP Linux server wasn't answering the ISP's router's ARPs because the proxy-ARP Linux server was never receiving the ISP's router's ARPs?

2. The Linksys RT31P2's routing capability is a bit more simple-minded than I thought, and may not be up to this task.

In the above diagram, I assigned the following representative IP addresses:

proxy-ARP Linux server eth0
Linksys RT31P2 WAN interface
Linksys RT31P2 LAN interface
firewall Linux server eth0
firewall Linux server eth1

The ISP's router in this representative example has the IP address

The proxy-ARP Linux server has these routes:
# route add -host dev eth0
# route add -net default gw

Because the proxy-ARP Linux server has an IP address on eth0, it also has the automatic route equivalent to:
# route add -net dev eth0

The firewall Linux server, in addition to its real public IP address on eth0, also has the alias as eth0:1.

The rest of my static IP addresses from my ISP are through Those are proxy-ARP'd on the firewall Linux server's eth0 outside interface, with routes pointing in through that firewall Linux server's eth1 inside interface.

The firewall Linux server has these routes:
# route add -net default dev eth0 gw
# route add -net netmask dev eth0 gw
(this last route should be extraneous and make no difference)

Finally, the routing table on the Linksys RT31P2 looks like this:

Destination....Default GW..Interface

I used tethereal to sniff on the proxy-ARP Linux server's eth0 interface, looking for ARPs. When I PING'd from the firewall Linux server, I saw that the destination MAC address of the ICMP echo request packets as those packets appeared to the proxy-ARP Linux server is actually the MAC address of the ISP's router. This suggests that the RT31P2 is not routing correctly.

Suggestions, analysis, pointing out where I'm being a dumb-*ss, &etc please? :)

I think that your best solution in this case would be to put the Linux box in the DMZ
I appreciate the attempt, and I'll be kind :) I do not think that would work.
I would try putting the Vonage device BEHIND your linux box, and then figure out
There are options for packet priority in the Linux kernel, and I worked with them
You seem to have created a more complex network setup than I've ever dealt with,
