Cisco Router locking out traffic on one IP address

You left out the part with the RAM and flash - kind of important for determining what images you are capable of running.

Yuck, 8M RAM and 4M flash. That won't run any IOS version Cisco still has posted, the lowest requirement I can find is 12M RAM and 4M flash. Since upgrading the RAM on this ancient beast would be a waste of time, I'd suggest you just replace it at this point. An 891 or ASA 5505 will run circles around this thing, and they are both available for less than $1K.

By the way, if you are looking to cut costs and want to stick with an IOS platform, the Cisco 881 is cheaper than the 891 but is still way better than a 1605R. List is $650 (and you should be able to do better than list) on the 881 versus $1300 on the 891.

Alternatively, you could look at something like an Adtran NetVanta 3120. They're much cheaper than even the cheapest Cisco router and I've used them in a number of places where money was tight. They support nearly all of the features that an ASA5505 Unlimited User Security Plus (~$1200) appliance supports. Obviously, performance isn't quite as good, but if you're getting by on a 1605 now, this will work quite well for you.

It's not IOS, but the CLI is familiar enough. Also, this device does not have a console port...SSH/telnet and web only, but the web interface is very usable.

Thanks again, you have all been a huge help. Like you have all pointed out the old beast is ready or should be terminated. I will take a look at the routers you have pointed out. I've looked at the 891 and it looked reasonable and had a lot of functionality, I'll definitely check the Adtran as well. I know when we got the new phone/T1 line a few months ago the phone guy who was supposedly Cisco certified was like I don't even know how to work on that. A sign, hmmm?
