RE:webex IP's

["michael" <madams () humanfactors com>]

As I recall, webex will give your company a specific web space based upon a
virtual name.  However, I belive that one IP you can block is 64.68.120.32,
which seems to be one of their core servers.

We use webex rather extensively and I'd love to find a lower cost
alternative to them.  Any ideas?

Subject: [fw-wiz] block webex?

I'm looking for a way to block WebEx communication to/from our company
network.  I'm interested in finding a reliable, easy to implement method for
our Win2K network.

We have Cisco firewalls in place, so my first thought was to simply block
the WebEx server Ips.  I'm having trouble locating a list of these
addresses, has anyone compiled a list they might be willing to share?

Thanks in advance!

Subject: [fw-wiz] Firewalls on an IPX/SPX network

Hello all,

I have a client requiring a VPN connection from his clients to his
network. He has Novell Netware 4.2 servers running at his site that
contains a database he'd like his clients to access form a program he's
written for the. The Program will be installed on the local PC, the
database will then have to be mapped via the VPN client.=20

He has, in the past enjoyed a strictly IPX/SPX network knowing that this
decreases his risk of exposing his servers. Is there a firewall product
out there we can use that allows a VPN connection to utilize IPX/SPX for
several and eventually tens of clients to map a drive to the Novell
server(s)?
=20
Clients will no doubt use DSL for connections

Thanks in advance,
Brian

Subject: [fw-wiz] FW: Wan Interface Speed

Hello again,

I am in search of a low cost appliance that will support 100 mb/sec on
our fiber connection to the Internet. Naturally, most of the SOHO class
appliances are limited to 10 mb/s. I am looking for something along the
lines of a Linksys / Netgear / D-link / WatchGuard / SonicWall /... that
allows 100 mb/s WAN throughput with most of, if not all, the standard
functions such as port mapping, filtering, etc. Reasonable cost would be
around $300-500. Any recommendations out there?
=20
Thanks in advance,
Brian

There is something to the idea of using IPX/SPX only on your LAN.  What
are they doing for internet-access, if I may ask?  You do mention that
the users would be using DSL/Cable for access.

Novell Bordermanager (http://www.novell.com/products/bordermanager/)
does have a VPN client, and I've seen documentation of past versions
include specifics of how to configure the VPN client for IPX access.
They've even received ISCA certification of their firewall product.
However, the latest version of the product requires Netware 5.1 and
eDirectory 8.6.2 to work, something your client is a few years away
from.

If he isn't afraid of running two NDS trees, it could work. I honestly
don't know if they still have IPX support in their VPN client, but they
did once-upon-a-time.

Dunno about a specific product, but since ipx is running on top of ppp
it should reasonably possible to make it run over pptp as well.
I don't know of any firewall that can do packet filtering or content
inspection on IPX, but maybe you can get some packet filtering with
cisco IOS (i have not used the ipx feature set for eons).

Regards,
L.
