My company recently just got T1 and gained 3 more static IP addresses. I found a 1700 series router for sale on the internet and found that I can get a ethernet wan WIC. Right now we just have a sonic wall that is connected to our CSU. My question is how many IP addresses can one ethernet wan WIC use? We have 4 IP addresses would we have to have a WIC for each IP?

We may create multiple virtual Interfaces with different IP.

Hi Dove,

Still learning on the CCNP side of things. Does this mean that you have to create the virtual interfaces on different subnets ? I am guessing if you have been given an address range with 6 addresss, then you would have the 1 ip address on the router and then NAT the others through ? Is this correct ?

Cheers

Again we rolled up with NAT :lol:


Here I ment that if he using the point-to-Point connection then we should go for Virtual Interface each with an IP.

If its Hub-n-Spoke network then Single IP is more than enough.


Hope I answered to your query.

Yup, slowly getting my head around having a different subnet on a NAT which i am pleased to say i know understand.

I was just wondering if you could have done that with NAT also.

IP which is using in router Serial is Inside Public IP
IP which is using for NAT translation is OUtside Public

so both are different.


Opps, dont understand that.......better get back to the books, hehe.

Take it easy
