Scott,
I would suggest using the bridge mode on the Apple routers. Generally only
tunnelling will cause you issues, but any VPN will probably use tunneling. You
should still be able to block MAC addresses in one of the manual airport
controls even with DHCP turned off.
My problem with NAT
Hi Jonathan,
THanks for the info. I was going to try bridge mode and have the gateway
handout the DHCP addresses, but of course this means I loose my DHCP
reservations. That isn't a big deal really and I could probably set the lease
time to something really long if it were necessary. As long

Hi.
In addition to what Jeff said, you should just be able to set you're airport
router to point to the comcast modem as it's default gateway.
Sounds like that tek at comcast needs to find a new job.

Hey Geoff,
Sorry I think there was some confusion in the communication. You are correct
that DHCP and static IPs have nothing to do with the local LAN. I think what
she was trying to say is that the modem effectively cannot be put into a true
bridge mode. I think the problem is she could not
I've slept on this one.
Is it possible to set the scope of the dhcp on the comcast device so
that it will only ever assign 1 ip address? This should mean that its
dhcp server just won't respond to any requests for ip's from clients
after its 1 ip has been assigned, leaving the airport to do all
Ben, I could do that. I might have to try this out and see what happens and I
also can adjust the lease time to something pretty long.
Thanks,

how come you need to use this modem? In theory at least, if it uses docsis, it
should work with any cable modem. Now, sometimes, if you have phone service as
well, one modem handles everything, or it could be that they don't follow the
docsis standards completely.

Hello Scott,
AFAIK, you always need public addresses for both ends of an IPv6 tunnel,
because they are included in the payload as part of the protocol.
This means your IPv6 network would have to be connected to the SMC and this
router would have to support IPv6 tunneling.
For normal Internet
This is for a business-class account and this is the only hardware available. I
could not switch out the modem since as a business-class customer I get other
benefits those using residential modems are not afforded.

Thanks for the info. THe SMC does support mac address filtering, but I am
actually using it to restrict access based on time periods for one of the
machines on the network. THe SMC does not allow this; however, the AirPort

Here is the situation. I recently switched to Comcast business class. I was

Hello Scott.
I've recently had issues of a similar nature. What I would like to do with my
network is to have the ISP box do what it was payed for to do and that is to
provide me with an internet connection and have the airport handle everything
else. I'm not a huge fan of devices with extra

Scott,
If I've understood you correctly, the comcast device is doing dhcp for
all of the computers on the network, but the computers are actually
connecting through the airport; you're wanting to make the comcast box
act just as a modem and nothing else because of the airports ip
reservation

Not sure if you're using wireless, but my suggestion is, use the routing
features of the com cast modem itself. This would mean you would need to give
up the mac address control but if you turn off the ss id broadcast and have a
good password for your wifi network, you should be fine. No sense

Ben and all,
Thanks for the feedback, but as I stated in my previous message, I neglected to
mention I cannot put the SMC cable modem in bridge mode. THat would have been
my preferred method for sure. You got the idea though, but seems that what I
want to do would cost me more money. :) One
Mike, the goal was not to complicate anything. The initial goal was to just get
up and running with as few changes as possible. They did the install in the
middle of my work day, so I had to just plugin and go. As is things work for
the most part, but for IPV6 tunneling and I can live without
