Hi Bill,
Linksys works fine as a NAT router. I do everything I can to avoid the
NAT router/WAP combo boxes though. No particular reason other than it
just doesn't seem "right" to me :-)
HTH,
Tom

Hi Tom,
Do you have a prefered NAT device ? As I have said until recently I
have had good luck with the LINKSYS box. Perhaps thare is somthing wrong
with mine.

Hi Bill,
I unfortunately have to agree with this. For any environment requiring
publishing, I always use a NAT device in front of it.
HTH,
Tom

The DDNS client doesn't really matter. That's not the issue. What is the
issue is the fact the publish rules can not handle the external IP of
the ISA server changing. At least its not obvious they can.
Reconfiguring the ISA whenever there is a dns change is a pain. It would
certainly be nice to be able to define the external interface in a
publishing rule without regard to its IP address. I would certainly
prefer to have the ISA server directly connected. It has never had a
problem.
Is this a all possible ?
There are also issues with configuring the external interface with DHCP.
It does not reliably receive a lease. Perhaps I have just not configured
something correctly.

I used to swear by Linksys, and now would not touch them. I ran my own
bank of tests with Linksys, D-Link, Netgear, and SMC. I bought one of
each of the wireless 802.11b from a local CompUSA and configured and ran
them for 2 days. Each and everyone of these products pretty much sucks.
They lock up, stop passing traffic on various ports, refuse to accept
wireless connections, etc. I did not find a single one that operated
flawlessly. The lastest versions (V4) from Linksys were especially bad.
I am currently only using D-Link for home office installs. They seemed
to be the least "sucky" of the batch.
D-link's tech support, however, appears to be not much more than a bunch
of 16-20 year olds that just happen to do tech support between LAN
Parties based on their level of knowledge and professionalism on the
phone. It was like trying to have a technical conversation with Spicoli
from Fast Times at Ridgemont High, dude.
Just curious, but is there an issue with running a DDNS client on the
ISA box itself and skipping the router? Is there a way to do some kind
of VBS with ISA to update the NAT tables in ISA from a DDNS client?

I had more luck sifting through their (Linksys) website than talking to
their support. Cisco has farmed Linksys support out of the country, at
least when I last talked to them.

Hello,
Yes I have, but I have not been able to get through to a high level tech
as of yet. I thought if someone else had solved this I could avoid the
game of 1000 questions the first of which is are you using a PC or a
MAC?
Thanks
Bill

Have you spoken to the Linksys support folks?
It sounds like you've narrowed it down pretty well.

Subject: [isalist] PPTP Question
http://www.ISAserver.org
Hello,
In order to use publishing it is necessary for the external IP address
of the ISA server to stay at a fixed IP. Unfortunately I have a DHCP
assigned address on my Cable Modem. My solution has been to install a
Linksys BEFSX41 router. This router has a DMZ port. I have my ISA server
configured as the DMZ host. In this way the ISA server always sees a
fixed IP address despite what the external address is. In addition this
router supports dynamic DNS updates so whenever the router's IP address
changes it updates my Dynamic DNS service. All of my published services
work find except PPTP. And this has only stopped working since updating
to the latest Firmware v1.45.3. Outbound PPTP works fine but inbound
PPTP to the ISA server does not.
Does anyone have any experience with this or suggestions about how allow
inbound PPTP to work. It was working fine in the v1.43.3 firmware but
that firmware has issues with working with DDNS.
Thanks
Bill
