I've finally got a working home based router/firewall built for EVDO.

Its an old Mini-ITX mb with a Ricoh PCMCIA to PCI adapter.

I'm running smootwall 3.0 with the kernel mods I patched in to support the Merlin S720 card and so far I have a stable PPP connection.

HOWEVER I can't get the default route to work. The PPP connection
sets a default gw to 0.0.0.0

I then manually set the default GW per the PPP connection to the default but still cant get pass traffic.

Anybody else have a problem with ppp settings when they make their EVDO connection?

I'm looking at the firewall too and that may be where the problem is.

My problems were with my 'smoothwall' firewall settings. The defined routing table of


smoothwall (root) /etc/ppp $ netstat -rnv
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
68.28.xxx.xx 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0

Looks odd, but traffic passes fine.

Now to get the external antenna on the roof to get speeds better than 1xRTT.
