routing question - please help

Hello,

I have a question that is somewhat related to the purpose of this list and I hope someone can help me.

I am attempting to setup a STRIP network (which uses wireless Ricochet modems). The wireless network is set up on a server I have on my LAN. Here are the particulars:

LAN: 10.0.0.0/16
STRIP: 10.1.0.0/16
Server: 10.0.0.1 eth0, 10.1.0.1 st0

I have ip_forward turned on. The problem is that packet from a computer on the wireless net (eg 10.1.0.2) do not reach the LAN, and vice versa. I can see from tcpdump that packets will reach 10.0.0.1 from the LAN, but they never get to their final destination.

Here is the output of route:

[root_at_scooter root]# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.0.0.0 * 255.255.0.0 U 0 0 0 eth0
10.1.0.0 * 255.255.0.0 U 0 0 0 st0 

127.0.0.0       *               255.0.0.0       U     0      0        0 lo
default         10.0.0.138      0.0.0.0         UG    0      0        0
eth0

Can someone tell me what I am doing wrong?

By the way, I do plan on putting a 802.11b wireless network off the same computer using hostap, and would like all 3 nets to be reachable by each other, so this problem is somewhat relevant to the list topic.

Thanks for your help,

Scott
