Re: Nortel Contivity 2600

I would think of DoS at first (certain versions of the Conctivity have
DoS vulnerabilities).

Although its VXworks architecture seems very robust, it does not look
right to me to have a VPN concentrator directly accessible on the
Inernet, why not place it in a DMZ (firewall protection makes sense,
and so does IDS/IPS)?

By the way, bear in mind Contivity also has a firewall module that can
run on its same platform, this could be very reccomendable if you are
to place it directly on the Internet.

Hope this helps,

Hi list!

I am looking for good reasons why I should move a Nortel Contivity
2600 VPN device behind a firewall.

Currently the device sits on the internet, and is used for VPN traffic
from other offices, and also for VPN dial-in users.

Are there any risks with this configuration? What comments can be made
around whether or not I should be placing this behind the firewall /
