Weird Routing to Default Gateway (SBC+2Wire+CIDR/29 NETWORK) |
|
|
Hello,
I am using sbc dsl with a 2wire 1800HW modem. I have a cidr/29 static
network from them.
I am finding that the the only way to to make my connection work
which is a 8 ip cidr/29 network is to pick the default gateway ip
address to be below the block of valid cidr ips.
The cidr is:
69.227.248.96 : NETWORK
69.227.248.103 : BROADCAST
69.227.248.102 : DEFAULT GATEWAY (as documented from sbc)
69.227.248.97-101 : 5 USABLE STATIC IPS
I find that both on windows and in openbsd if I use a default gateway
address of 69.227.248.95 i get connectivity. If I use the sbc
documented default gateway address of 69.227.248.102 I can't get any
connectivity.
Because this is a CIDR/29 network I can only get the bogus default
gateway ( 69.227.248.95 ) to work on openbsd if I fudge the network
mask to 255.255.255.0 instead of 255.255.255.248. With the correct
netmask of 255.255.255.248 openbsd will not route add the default
gateway address of 69.227.248.95 ( obviously ).
Who administrates the default gateway? is this a modem issue or a sbc
internet routing/setup issue?
Any general comments on this situation?
Thanks,
-Tom- |

I have a very similar confiugration, SBC+Speedstream 5100+CDIR/2
Network. I don't think the problem lies with the modem itself. I hav
tried talking to their tech support multiple times but I have not bee
able to get any straight answers. Right now all of their tech suppor
is outsourced to india I believe. I'm planning on purchasing a 2wir
modem in the next week or so, I'm sure I'll run into the same issues
I'll try to post again if I find out any more information

I thought the 2wire was just a modem/router for NATing a single public
PPPoE IP. Does it have configuration for using it with a /29 static
block? Routers compatible with static block on SBC PPPoE are listed at
http://www.broadbandreports.com/faq/3759 which should work fine with a
5360, 5100a, or 5100b set to allow computer to do PPPoE (computer in this
case would be the router).
Maybe there is confusion about what is default route for which machines.
The router should have netmask 255.255.255.255 on its public WAN and
only a default route to the remote PPPoE IP. If the public /29 block is
passed through the router, LAN IP of router should be an IP within the /29
block with 255.255.255.248 netmask (no default route on that interface).
Computers behind the router would have netmask 255.255.255.248 and default
route to LAN IP of router (or modem/router) doing the PPPoE.
Unless you find verification that the 2wire is suitable for working with a
/29 public IP block, I would look for other methods that are known to work
properly. |

I am sure you are finding that the the only way to to make your
connection work which is a 8 ip cidr29 network is to pick the default
gateway ip address to be below the block of valid cidr ips.

I'm not exactly sure what the technical issue is but I believe some
sort of UNIX system registry stops in 2038.

Music is much less centralized. The general trend is away from
"computer generated" music and more toward real people playing real
instruments.
If you put tomfoolery into a computer, nothing comes out of it but
tomfoolery. But this tomfoolery, having passed through a very
expensive machine, is somehow ennobled and no-one dares criticize it.
