ARP problem.



Hello,

I'm trying to correct firmware for Edimax BR-6204Wg WiFi/router ->
RTL-8186(MIPS 4Kc), 2M flash / 16M RAM, kernel 2.4.18.

My config is:

--------------
| Edimax |
| |
--------------
| |
WiFi |
|
|
--------------
| Switch |
--------------
|
WiFi |
--|------------
| PC |
--------------

Adressing: LAN is 192.168.1.0/24 WiFi is 192.168.2.0/24.
Edimax is Wireless ISP mode.

Problem: when I try to send something (ex ping) from Edimax to PC THRU
WiFi, at the beginning it works. After ARP times out, response is "no
response from PC". /proc/net/arp shows PC IP addr with zeros (unresloved
AFAIK).

If then I issue ex ping from PC -> ARP becomes valid, ping works.

Question: where to look to try to solve this? Does IPTABLES on PC in
some kind blocks ARP? (as it name suggests it shouldn't). On PC I have
full normal "toolkit", but on Edimax my tools are VERY limited.

Anyone has ideas??

W.P.
.
