Hello,

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-
