Okay, so I did guess correctly that your problem was in being able to talk to a device that was on 192.168.1.1 when your own network does not include that IP address. > That of course did NOT work. There's no reason why that way couldn't be made to work, so if anyone else is trying to do this in that way in future, don't be discouraged. > So, I wound up with this in /etc/network/interfaces: > iface eth0 inet static > address 192.168.71.3 > netmask 255.255.255.0 > gateway 192.168.71.1 > > iface eth1 inet static > address 192.168.1.3 > netmask 255.255.255.0 > gateway 192.168.1.1 Assuming you do actually have an eth1 (most people don't, and even one Ethernet device is getting rarer, as more things go to wifi-only), again there is no reason why this shouldn't work. Although this doesn't look like a full interfaces file as it is missing "auto eth0" and "auto eth1". > But the networking script in /etc/init.d, true to its word, would not > bring up eth1 on a restart, so that required an "sudo ifconfig eth1 up", > followed by a 'sudo ifconfig -a' which then returned: ifconfig is deprecated and we should really be using the "ip" command now, though as you've found ifconfig can still be made to work. It appears in your case that restarting networking has done *something* as your eth1 interface has the address and netmask you set in the interfaces file, but wasn't actually brought up. Your subsequent ifconfig commands bring up the interface and then display all interfaces and we then see it is configured correctly: > eth1 Link encap:Ethernet HWaddr 00:1f:c6:63:07:97 > inet addr:192.168.1.3 Bcast:192.168.1.255 Mask:255.255.255.0 > UP BROADCAST MULTICAST MTU:1500 Metric:1 > RX packets:0 errors:0 dropped:0 overruns:0 frame:0 > TX packets:51 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:1000 > RX bytes:0 (0.0 B) TX bytes:38903 (37.9 KiB) So, I think we could have made it work with /etc/network/interfaces alone. I suspect that the entire thing could have been achieved with: # ip address add 192.168.1.3/24 dev eth0 to begin with. > Everything but ARP is happy.

Adjusting ARP timers may be too low-level a feature for a consumer router. You may have to reinstall it with Open-WRT or similar to get access to those settings. Myself, I'd probably just not worry about it if everything else is working, as the traffic is minimal. :) Cheers, Andy -- http://bitfolk.com/ -- No-nonsense VPS hosting
