Secondary IP address Cisco 678

[hereigns]

Got a cisco 678 and was wondering if someone has figured out how to add a secondary ip address (one for the WAN and one for the LAN)?

I tried both of these but neither works...
set interface eth0.0 a.b.c.d
set interface eth0/0 a.b.c.d

Mucho Gracias.

Aww man my old ISP used to send these out to customers in the early days of DSL quite a long time ago. My knowledge is somewhat rusty and I never had a need to configure a secondary address but you may be able to do what you want by configuring something called a virtual interface (vip).

To configure a vip. you can do the following:

set int vip0 address 10.1.1.1

Virtual interfaces are usually associated to NAT configuration and you can make them inside or outside interfaces with the following command:

set interface vip0 inside

Of course your ethernet interface is also an inside interfance. I believe if you then set the vip0 inside as well this is pretty much the same as configuring a secondary ip address for the LAN.

You can repeat this process and create an outside virtual interface (vip1) for the WAN if you need a secondary address on the WAN.

I admit I've never needed to do this before but we had to configure NAT a few times on these 600's. Hopefully this will help you out.

Give it a go and see what happens. If you're still in trouble, let me know and I'll search what documentation I can find about the 600 for you.

HTH

KiscoKid,
Thanks for all the helpful information/insight. I'll give her a try and let you know what I find.

Thanks again!

KiskoKid,
I gave it a whirl and your steps worked like a charm. However, I'm unable to get past the router on the private subnet. I did a traceroute from the private LAN to google.com and it stopped on the route past the router. I tried adding a static route entry for the private LAN:

192.168.8.0/24 192.168.8.2 (device that talks to both WAN and LAN)

But that didn't help either, not sure why, any ideas?
Here's the running config and route table on the router

***Config****

although ive never configured one of these routers
it appears your missing your IP NAT outside statement
and possibly an overload statement...
i would say thats whats holding you back

 

[hereigns]

plshlpme,
Thanks but can you be anymore specific? I've not configured a router with NAT prior to this one. What should the NAT outside statement look like?

 

[plshlpme]

sorry bud. ive never been in one of these routers...

maybe
