How to set up a 2610 or 2620 to replace a standard home router?

[Mizugori]

I recently bought two 2600 routers (a 2610 and a 2620; the 2620 has two ethernet ports). Each has a t1 card installed. I also bought a 2900xl catalyst switch.

How could I set this up almost like a small business type office?

can i do:

modem --------> 2620 ethernet port 1

any port on switch --------> 2620 ethernet port 2

? then how do i configure the router? i changed the password when i got it but other than that haven't configured it. also, this means no firewall right? (whereas most home routers have a rudimentary one built in) could i pair it with a cisco pix 501?

thanks!!

yes that is possible. you would have to config a fast eth port for static or dhcp address, add in some routes. post a scrubbed config of the router

 

[unclerico]

A few of them would be like this:
modem -> 2620 -> Pix -> 2900 -> 2610
modem -> Pix -> 2620 -> 2900 -> 2610
modem -> 2620 (with IOS firewall) -> 2900 -> 2610

Are you using DSL or Cable??

cable, what is the advantage to using both routers?

 

[North323]

well...what do routers do? they route traffic and/or segment networks. so if you have more than one subnet at home, like 192.168.1.0 and 172.16.5.1 and you need those two networks to communicate, a router comes in handy. really depends on what your goal is.

 

[unclerico]

what is the advantage to using both routers?

to kind of add to what north said, i assumed that since you purchased two of them that you'd want to use both of them. if you don't want to use both of them then don't, it's up to you.

Is who from MO?

I bought 2 because you need two to do a lot of the ccna practice labs/activities.

I'm sorry I wasn't clear I just meant, on a small home network, would there realistically be any advantage

 

[North323]

with one subnet like 192.168.100.1...NO there is not advantage

 

[burtsbees]

There are disadvantages, such as throughput slowdowns, etc.

Missouri---are YOU from Missouri, Mizugori> The handle looks like maybe you could be. I'm in St. Louis, which is why I ask.

anyone willing to step in with some config help? here is the current status of the 2620:

[burtsbees]

First off, change the config register to 0x2102. Second, how exactly are you laying things out? You will likely need IP Plus, which I have...that is the feature set necessary (IOS) for what you want to do.

ok, here is the show run, can anyone help me configure it as though I were setting up my home as a small office?

[Mizugori]

can anyone tell me what the literal commands are to change settings regarding the interfaces? ie how do you set an ip address on the fast ethernet 0/0 interface?

how do i "Set the internal port (e0/0) with a static IP address in the range of the internal network (in this example 192.168.1.0/24), and assign it as the 'inside' NAT interface:"

thanks!

Now are you wanting the router to NAT? Also, get 16MB flash for it...I may (actually, do) kknow someone willing to share (moi) an IOS that will let you do a VPN, ssh into it, firewall, IDS, IPS...

thanks a lot, can you please email me about that? mizugori AT gmail DOT com

You would need to upgrade the router's flash to 16MB...
