OK, here is my situation. I have added a wireless access point to my existing
lan. In the process, I decided to use a linux box as the AP and as my main
router.
The router has 3 network cards in it, 2 ethernet (eth0, eth1) and 1 wireless
(wlan0).
eth0 - 10.1.21.0/24
eth1 - WAN
wlan0 - 10.1.20.0/24
eth0 has an IP of 10.1.21.1 and wlan0 has an IP of 10.1.20.1 with DCHP enabled
on both of them. I know for a fact that DHCP is working properly. I'm
having DHCP kick out the default route to be 10.1.21.1 and 10.1.20.1 on the
respective networks.
Here is my problem. I can ping the gateway from both networks. From the
10.1.21.0/24 network I can ping all clients and I can ping the 10.1.20.0/24
network. BUT when I try to ping the 10.1.21.0/24 network from 10.1.20.0/24,
I can't. I can't even do it from the gateway.
Here is the output from /sbin/route
255.255.255.255 * 255.255.255.255 UH 0 0 0 eth0
255.255.255.255 * 255.255.255.255 UH 0 0 0 wlan0
10.1.20.0 * 255.255.255.0 U 0 0 0 wlan0
10.1.21.0 * 255.255.255.0 U 0 0 0 eth0
loopback * 255.0.0.0 U 0 0 0 lo
I don't currently have a default gateway set. I did have it set to 10.1.21.1
and it still did not work. I know I need to use iptables to forward packets
around. I have my kernel configured to do iptables/netfiltering and iptables
are installed.
Any suggestions on to my problem??
If more information is needed, please ask and I will give it out.
Thanks in advance for your help.
Curt
