Hello to all ..
I am moving from AS5300 to AS5350 now. Could someone spare experiences in
this area?
Some notes about useful IOS and major changes to AS5300 would be great ?

Greetings,
I wonder if anyone has managed to successfully setup a VPN between a Cisco
PIX
and Microsoft ISA firewall? I am confused about the Windows will not do
tunneling statements and also the (apparent) lack of direct ipsec
configuration in ISA.
I did find articles on the Cisco website
Hi there,
First of all, a BIG thank-you to all of you who gave me tips. Trust me, they
really helped. The thing which I learned for this exam are as follows:
1. Know the Cisco official study guide cover to cover
2. Know the product guides very well
3. Nothing replaces hands-on
Good luck to you
Dear all,
I passed BSCI 640-901 on Saturday with a score of 767/1000. I'm not overly
pleased with the score or how I performed but my preparation wasn't the best
in the fortnight leading up to the exam and I felt awful on the day of the
exam (heavy cold). Also had Prometric mess me around (again)
Consider the following topology:
area_0---ABR_1area_1-ABR_2area_0
There are two area 0's.
Use a virtual link to connect the area 0s.

If you look at my diagram it is not terminating on the pix and the first
post does not say he is terminating on a pix, he just simply stated that
he is trying to go through a microsoft box to his vpn corporate network.
Because he was told that nat will not work with PAT (udp encapsulation)
Robert,
Aux could only work if you had configured the router
before now to accept Aux connections.
The only posible solution is for you to go through the
console port.
Using a PC with a Terminal emulator set its parameters
to:
9600 baud rate
No parity
8 data bits
1 stop bit

Please correct me if I am wrong but you are using a router with PAT, and
