Multiple WIC-2Ts

ziutek · ‎05-20-2004

Greetings to all.

I was jsut wondering if I can install two WIC-2Ts in a 2611 with no problems. The unit has 64/16 running enterprise plus IOS. And if so, what is the numbering scheme? I know that one WIC-2T will use Serial 0/0 and 0/1. Would the second WIS2T use 1/0 and 1/1? The problem I see with this, is what would happen if I installed for example a NM-4A/S later. Since the free NM slot is slot one, and the interfaces would be numbered normally 1/0 - 1/3.

I am asking because I need to put 4 serial ports in this 2611, and already have one WIC-2T, and just want to make sure that the 2611 will support two WIC-2Ts before I go any buy one and a pair of cables.

Thanks,

Joe

I can give example of a router which i have deployed.

It's 2620. It has two WIC-2T cards and One NM 8A/S.

They are numbered as:

For WIC Cards S0/0,S0/1,S0/2,S0/3

For NM Card:S1/0,S1/1,S1/2,S1/3,S1/4,S1/5,S1/6,S1/7

Flash:16 RAM:48

I am facing problems configuring nat.

we are connecting central site to remote site using dxx link.At both ends we have 1751 routers.Task is to let the computers on remote office to access the internet from cental site.Network at central site is 192.168.1.0,network at remote site is 192.168.4.0.Computers at central site connect to internet through a deicated connection using linyx server.

At central site a PC access the internet by simply defining the gateway of

Linyx server and no proxy server settings required at PC.

We have a number of free IPs in 192.168.1.0 network.Therefore, i am trying

to configure NAT to work in a way that when a remote office IP e.g 192.168.4.2

enters central site router,it is converted to e.g. 192.168.1.80(which is a free IP at central site)

and then it should be able to access internet.

But after a lot tries,,Computers at Rmote office are unable to access internet.

I have tried both static and dynamic mapping.

Configuration:

interface FastEthernet0/0

ip address 192.168.1.81 255.255.255.0

ip nat outside

!

interface Serial0/0

ip address 192.168.100.1 255.255.255.0

ip nat inside

!

ip nat inside source static 192.168.4.2 192.168.1.85

Sample Debug output:

May 20 17:49:24 PST: NAT*: s=192.168.4.2->192.168.1.84, d=192.168.1.3 [31548]

May 20 17:49:24 PST: NAT: s=192.168.1.3, d=192.168.1.84->192.168.4.2 [11908]

May 20 17:49:24 PST: NAT: s=192.168.1.3, d=192.168.1.84->192.168.4.2 [11909]

May 20 17:49:24 PST: NAT*: s=192.168.4.2->192.168.1.84, d=192.168.1.3 [31551]

May 20 17:49:24 PST: NAT: s=192.168.1.3, d=192.168.1.84->192.168.4.2 [11910]

May 20 17:49:24 PST: NAT*: s=192.168.4.2->192.168.1.84, d=192.168.1.3 [31553]

May 20 17:49:24 PST: NAT: s=192.168.1.3, d=192.168.1.84->192.168.4.2 [11911]

Please Guide.

Dear All,

Problem is solved.Thanks to the default route that I

added in the Central Site Router

i.e. 0.0.0.0 0.0.0.0 192.168.1.2

and ofcourse another default route at the Remote office router

i.e. 0.0.0.0 0.0.0.0 192.168.100.1

Right after i did this, Remote office computers were able to access the internet.

Here's the Configuration

Central Site:

interface FastEthernet0/0

ip address 192.168.1.81 255.255.255.0

ip nat outside

!

interface Serial0/0

ip address 192.168.100.1 255.255.255.0

ip nat inside

!

router eigrp 64

network 192.168.1.0

network 192.168.100.0

ip route 0.0.0.0 0.0.0.0 192.168.1.2

###where 192.168.1.2 is the degault gateway compputer

on which internet link terminates###

!

ip nat pool test-pool 192.168.1.86 192.168.1.94 prefix-length 2

ip nat inside source list 1 pool test-pool

access-list 1 permit 192.168.4.0 0.0.0.255

!

end

Conclusion:

I am glad that problem solved also becuse there was a genuine reason for that.

any traffic destine for internet requires a default route because there are a number of internet IPs and one can never define all the networks in a single router.Therefore, a default route entry is must in this scenario.

Regards.
