A quick query about something that's causing a few problems at work.
We're using a Cisco router (IOS) so that people can connect to our
network using the Cisco VPN client (on Windows).
Is it usually a problem to route between two hosts both connected using

I'm like most companies; I use both the 192.168.1.0 and 10.1.1.0
subnets.  Unfortunately, when my coworkers travel or go home they often
get these same addresses from their networks.  Currently we don't have
a good solution to this problem.  If someone could point me in the

I thought I would share a very useful open source network management
application that we use called NeDi.  You can read about NeDi at:

Hello all, I am looking for a way to dump the output of the following

Is it possible to use a WIC-4ESW as a L3 device in a IOS based router (28xx)
I noticed the MAC addres of  the Fa0/0 is the same as the VLAN interfcae

I am looking for a reading material on TACACS+. I searched the net,
specially cisco, cisco press. but not able to find which will help me
in my understanding of protocol. There are docs which talks abt
configutaion but that is not what I am looking for. I could find a

I was hoping someone could help me with a problem on my Pix.  I am
getting high collisions on my inside and outside interfaces.  The ISP
is also seeing collisions.  The interfaces are set to auto but drop to
10 half duplex.  Does anyone have any ideas on where I should start?

Is there a limit as to how far you can use NBAR in conjunction with
class-maps and QoS?  I remember reading somewhere that using QoS in
this manner on a slow link like a T1 is okay, but shouldn't be done on
a 45mb DS3.  Is that true?   Does NBAR still allow CEF forwarding or

Sorry to re-submit the question, however, I got somewhat further. Our
c836 router loses connection every five minutes. The line is ok, other
modems work fine. Our provider can see no problem. Can this have
something to do with my config? At the moment it is still very simple,

What is P (Push) flag in TCP used in real life ?
Could cisco block such packets somehow ?

Does anyone know if it's possible to add an IP address to the system portion

FWSM since you session in to it, but since they both operate off the same
basic principal.

Trying to understand multicasting from the client/host perspective ..

Hello, I have several 1721 routers, each with 56k frame wic and an
analog modem wic (WIC-1AM).  They are configured to dial-on-demand into
our network if the primary frame link goes down.  My question is, and
this is probably easy for someone, how do I disable the auto-answer

  I have 2811 cisco router with 3 leased line and 1 isdn. All three
leased circuits would be using the single ISDN for backup. I know that
you can use different dialer profile to call different numbers for each
circuit (with different ip address and routing). What i want to know
