List.
I have a Cisco 1720 w/a T1 WIC Card and a BRI U Card.
The Router is set up so that if the T1 line goes down , the ISDN line kicks
in.

We're dumping our frame-relay and moving to Internet T1's all off ATT's
backbone. However, we have yet to decide on how to configure the VPN
architecture. We have a good amount of experience with PIX-to-PIX and
PIX-to-Concentrator VPN configuration.

We use HSRP and have always used public address space for 'real interface
ip' ddress's
Would it make sense to use non routing private address space IP's for the
'real' interface IP's and of course a public IP for the floating ip.

What are some good tools/methods for troubleshooting PIX access-list
issues?  For example, say that I'm blocking all outbound smtp for all
machines with the exception of our authorized email servers (as noted
in sample below).  The email admin stops by one morning and says that

is it possible to use snmp to query / add / delete / modify access-list
configured in a PIX firewall?
Where can I find such information.

If you can help me, I want to ask you a question, I want to know if it's
possible to create 2 or 3 vlans on the same subnet address without create
separate subnets for each vlan.
Thanks

I have a 7206vxr that should be aggregation point for DSL users. Since,
right now I have never worked with dsl techmology, I was wondering if it is
possible to simulate dsl/dslam story between user and BRAS.
For example on CPE side I have pc with ppoe client and on central side I

we have a PIX 515(ER) running v6.3
Currently we are using the local database of the PIX for
authentication of remote telent and SSH connections, using the
following commands:

I've been looking intently at the Cisco website documentation (not all
of it seems correct/complete) and have successfully set up a PIX515 to
PIX506 site-to-site tunnel.  In addition, I have VPN Clients set up to
access the PIX515 and can access the network behind the PIX515.

I have been through 9 months training on Cisco routers and switches, 3
months on CCNA and 6 months on CCNP and have failed the 640-801 twice.  I
have passed all three of my classes with a minimum of 105 (top scores for my
classes) I can configure anything in those 6 books by memory ...

We are having problems with getting a Cisco 3640 to boot an IOS from
tftp.  The IOS is too big to copy to flash.  I do have one 3640 that
is working fine running this same IOS from tftp and it has the same
amount of physical memory, flash, etc.

somehow, to my

I was told that a 1600 could be configured
to route between the 10BaseT and the AUI
ports.  Can anyone verify that this is true?

   I have not used these cards before and would like to confirm my
understanding of their configuration is correct. I want to put 3 of these in
a 3745 to support 5 full data T1's that reach to 5 remote sites. ( hub and
spoke network configuration ). I am not sure if I am using the ...

I am monitoring traffic of a voice VLAN of the IPCC, thru a SPANning
VLAN traffic to my server's network port.
After dumping IP calls voice traffic into files, most of the calls are
ok, but say 10% of calls has about one minute of lost voice packets.
