Configuring Apple Extreme as router and DHCP Server with Hughesnet 1100 modem

After gruling hours of trial and error, I finally configured my Apple AirPort Extreme as my LAN DHCP server and as a router to hand out IP's withing a giving subnet and scope.

The HugesNet HT-1100 modem does not allow the user to configure any settings whatsoever. It defaults to being its own DHCP router and will not conform to my existing subnet of 192.168.0.xxx because there is no user management interface.

I can't "see" the HN modem from my LAN becaus it's on a separate subnet. The download speed is great, BUT the DNS speed is very very slow. Somehow the AAE inherited the following DNS address from the HN modem:

192.168.0.1, 2001:5b0:2191:258:9272:40ff:fe03:c283

The 192.168.0.1 IP is the LAN side IP of the AAE.

The 2001:5b0:2191:258:9272:40ff:fe03:c283 address somehow is getting inherited from the HN modem to the AAE, but I don't have the faintest idea what protocol this is.

I would like to specify known faster DNS IP addresses such as:

216.146.35.35 which is DynGuide, a free DNS service, but it does not jive with the modem IP address of 100.104.128.241.
Also, interestingly, and something I'd never heard of, I had to check the IGMP Snooping on the AAE. In doing so however while finally gaining fully resolvable Internet service I can no longer control my DNS server settings.

Any ideas, suggestions, or support greatly appreciated.

TIA,

John

By default, with NAT & DHCP enabled, the AirPort Extreme would have a LAN-side IP address of: 10.0.1.1. This would change to 192.168.0.1 if the base station administrator switched the DHCP scope.

The other address is an IPv6 address. All consumer routers today do NOT offer NAT translation as it is not required for IPv6 ... and IPv6 traffic is not blocked unless you specifically block it.

I would like to specify known faster DNS IP addresses such as:

216.146.35.35 which is DynGuide, a free DNS service, but it does not jive with the modem IP address of 100.104.128.241.

Typically, you can "override" your ISP's DNS servers by entering DNS server information manually in your router's configuration. With DHCP enabled on the router, these would be provided to network clients. On the AirPort Extreme, you can set these via the AirPort Utility on the Internet tab.
