WRT54G Unpredicable MAC Address Behavior

    Internet <--wire--> Router (Linux) <--wire--> WRT54G-1(WDS) <--wireless--> WRT54G-2(WDS) <--wire--> client1 ... client3

    The problem is this: Some packets from the clients come with other client MAC address. (packet from client1 come with client2 mac address)

    tcpdump output on WRT54G-1 (with bad mac info):
    Code:
    00:e0:4c:09:70:23 > 00:10:a7:08:ee:37, ethertype IPv4 (0x0800), length 66: IP 192.168.0.67.5900 > 192.168.0.1.34119: . ack 6 win 17515 <nop,nop,timestamp 2344082 646576592>
    tcpdump output on WRT54G-2 (with right mac info):
    Code:
    00:12:f0:66:70:19 > 00:10:a7:08:ee:37, ethertype IPv4 (0x0800), length 66: IP 192.168.0.67.5900 > 192.168.0.1.34119: . ack 6 win 17515 <nop,nop,timestamp 2344082 646576592>
    router IP/MAC: 192.168.0.1/00:10:a7:08:ee:37
    client1 IP/MAC: 192.168.0.67/00:12:f0:66:70:19
    client2 IP/MAC: 192.168.0.68/00:e0:4c:09:70:23

    checked with: hyperwrt, sveasoft, dd-wrt firmwares
    WRT54G HW ver.: 2.0

    Any ideas on what might be causing this MAC problem?
