You could be right there :) It never hurts to add information (especially in this case as you'll see). You're running 2.2, right?

You want the network 205.178.55.64/26. Replace "205.178.55.0" with "205.178.55.64" in your iface stanza and that route statement, and see what happens. I'm trying to think of a good reference for classless routing (aka variable-length subnet). It's not hard to learn, but it can be daunting to the newcomer. I'm also not sure that having two gateway lines is a good thing. Usually a router knows about one default gateway unless it wants to do some sort of round-robin load balancing, and I'm quite sure you have to choose extra bits in teh kernel config to do that. Perhaps comment out one or the other. Are 205.178.55.65 and 10.0.0.41 the same router? > trs80:/etc/network# route -n ^^^^ love the hostname :) > Kernel IP routing table > Destination Gateway Genmask Flags Metric Ref Use > Iface > 205.178.55.64 0.0.0.0 255.255.255.192 U 0 0 0 This is the route that the kernel added automatically, I guess. Note the network is 205.178.55.64 rather than 205.178.55.0. Hmm, perhaps the problem here is that the route is bound to eth0 rather than eth0:0, but I'm not so sure about that. > Thanks for all the help. > I am kinda struggling here, since I've been forced into a sysadmin role > without > any experience or training (company can't afford a real sysadmin, I'm > the only > person with *any* kind of linux experience, since I run debian at home.) Well, you've got a good start imo; I learned everything I needed to know about routing from running Linux :) (Ok, most everything).
