I have about 9 Cisco networking devices including PIX Firewalls cisco routers & switches. I want to develop a solution where in case of a network outage, me or my team members can remotely access the devices from my home without having to rush to the colocation. Now, I remember from CCNA about AUX port in the routers used for access over the WAN through modem. But I think in that case, I would need separate modems for each of those 9 devices, right ? (Please correct me if am wrong).
I was having a read of this link
where it looks like a central device having console access to all the devices with only 1 modem required. I'm just trying to develop an understanding of how I am going to set this up so I'll break my questions into points.
1. I place this router (labelled Router 1 Terminal Server in the figure) outside the firewall and assign it a public I.P ? right ? I do have a couple of spare IP's from my public I.P pool so I can use that.
2. I can't picture how will I connect Console port of this router to all different consoles ? Do I need to use something in between ?
3. What specific modem do I need to use at my end for making a successful connection to the Aux port of this router ? Similarly, what modem at router (terminal serve) end ? Is it going to be an IP or non-IP solution ?
4. What's the significance of the this command ?
ip host 3600-2 2013 172.21.1.1.
Is it telling the Terminal server router to where its connected to the different networking devices ?
Sorry, but am trying to get the picture clear to know if it's possible to implement this setup. What model is typically used for terminal server. Is it an actual cisco router or is it a dedicated appliance ?
