Re: How do I configure my 5861 when I get my static IP

said by dslknowitall:
When we talk about 5 ip's we are really discussing what is called a routed
NOTE: An 8 IP subnet can also be called a /29 in regards to the subnet mask
(which would be 255.255.255.248). This might be mindless techo-babble but I
Example of a breakdown of a routed subnet:

I have heard Ameritech gives IPs like that, and I understand the breakdown of the subnet just fine.

This is what I specifically want to avoid. This would mean having to use 192.168 addresses in my computers on my LAN. I do not want this. I would like to be able to put the 169.129.154.x (or whatever its going to be) address directly into the IP configuration on my windows and/or Linux boxes.
Is this possible with the 5861 (which I already own, so no sense buying a different router now) ?

Is it possible, yes (in theory). But it's not a current configuration that's known. Now if I actually had an IP block then I'd have tried by now, but since I don't I can only postulate. Since typically bridging is enabled, you might be able to define the IP address with a gateway of the router, or whatever is in the redbacks router table as the next hop (in theory the first ip of the subnet).
Doing it the way above though isn't necessarily a bad thing, as it forwards all port traffic for the global address to the private IP. It may not be what you want, but it certainly would allow running a web server, email server, etc with no problem. Either way its the only way i know of for sure that works, but if you wanna experiment I'm all ears to hear your results

I did something along the lines of what you're looking to do - I can't give a nice list of commands like dslkia did because I ended up using the Windoze configuration software that comes with the router. I'd *intended* to do it with the CLI but 379 pages of CLI reference manual wasn't compatible with getting things working quickly

It was pretty straightforward using the GUI (which had the added advantage that it automatically backed up the router config first). I just turned off NAT, set up the IP, gateway, subnet etc as specified, turned on some filtering, saved and rebooted and...that was about it, really. If you plan to continue to use the built-in DHCP server, you'll need to change the settings for that too - the only two IPs I'm using so far are both statically assigned, so I turned it off.

Note that the admin IP stays the same (it can be changed, but only from the CLI, I think) - however, if you have the 5861 as your default gateway for machines behind it, that shouldn't be a problem.
