I have some more information now.
I'm sorry, its a bit long winded, but I thought I'll document my experiment.
pf is disabled.
ip forwarding is disabled
I am completely stumped and will really appreciate any input.
Thanks & Regards,
Anwar.
Experiment follows:
--------------------------------------------------------------------------------------------------
computer1 --------- wi0 - bridge1 - sis2 ---------------------computer2
(192.168.5.3) (soekris machine with no ip assigned) (192.168.5.1)
ping 192.168.5.1 from computer1 (192.168.5.3)
On Soekris:
tcpdump -i wi0
22:44:47.170157 arp who-has 192.168.5.1 tell 192.168.5.3
22:44:47.170528 arp reply 192.168.5.1 is-at 0:6:5b:d7:bf:f7
22:44:48.190277 arp who-has 192.168.5.1 tell 192.168.5.3
22:44:48.190618 arp reply 192.168.5.1 is-at 0:6:5b:d7:bf:f7
tcpdump -i sis2
22:45:34.080259 arp who-has 192.168.5.1 tell 192.168.5.3
22:45:34.080350 arp reply 192.168.5.1 is-at 0:6:5b:d7:bf:f7
22:45:35.100330 arp who-has 192.168.5.1 tell 192.168.5.3
22:45:35.100421 arp reply 192.168.5.1 is-at 0:6:5b:d7:bf:f7
--------------------------------------------------------------------------------------------------
Similarly,
ping 192.168.5.3 from computer2
On soekris:
tcpdump -i sis2
22:46:55.190161 arp who-has 192.168.5.3 tell 192.168.5.1
22:46:57.190171 arp who-has 192.168.5.3 tell 192.168.5.1
tcpdump -i wi0
22:47:41.210268 arp who-has 192.168.5.3 tell 192.168.5.1
22:47:42.210266 arp who-has 192.168.5.3 tell 192.168.5.1
So it looks like the bridge works.
---------------------------------------------------------------------------------------------------
On soekris initially, no inet4 address assigned:
wi0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
address: 00:02:6f:33:bc:66
ieee80211: nwid test2 nwkey 0x31415926535897932384603141 -21dBm (auto)
media: IEEE802.11 autoselect ibss-master (DS11)
status: active
inet6 fe80::202:6fff:fe33:bc66%wi0 prefixlen 64 scopeid 0x8
On Soekris, Now assign an IP address:
/root# ifconfig wi0 192.168.5.2 up
/root# ifconfig wi0
wi0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
address: 00:02:6f:33:bc:66
ieee80211: nwid test2 nwkey 0x31415926535897932384603141 -21dBm (auto)
media: IEEE802.11 autoselect ibss-master (DS11)
status: active
inet6 fe80::202:6fff:fe33:bc66%wi0 prefixlen 64 scopeid 0x8
inet 192.168.5.2 netmask 0xffffff00 broadcast 192.168.5.255
-------------------------------------------------------------------------------------------
Now:
computer1 --------- wi0 - bridge1 - sis2 ---------------------computer2
(192.168.5.3) (192.168.5.2 on wi0 (192.168.5.1)
no ip address on sis2
soekris)
-------------------------------------------------------------------------------------------
ping 192.168.5.2 (soekris wi0) from computer1
On soekris:
tcpdump -i wi0
22:52:33.710202 arp who-has 192.168.5.2 tell 192.168.5.3
22:52:33.710526 arp reply 192.168.5.2 is-at 0:2:6f:33:bc:66
22:52:33.711016 192.168.5.3 > 192.168.5.2: icmp: echo request
22:52:33.711283 192.168.5.2 > 192.168.5.3: icmp: echo reply
22:52:34.740159 192.168.5.3 > 192.168.5.2: icmp: echo request
22:52:34.740413 192.168.5.2 > 192.168.5.3: icmp: echo reply
It works! (So it looks like the wireless network is also working)
I do receive the ping replies on computer1.
---------------------------------------------------------------------------------------------
Similarly, from computer2
ping 192.168.5.2 (soekris wi0) from computer2
On soekris:
tcpdump -i sis2
22:56:15.620077 arp who-has 192.168.5.2 tell 192.168.5.1
22:56:15.620251 arp reply 192.168.5.2 is-at 0:2:6f:33:bc:66
22:56:15.620982 192.168.5.1 > 192.168.5.2: icmp: echo request (DF)
22:56:15.621159 192.168.5.2 > 192.168.5.1: icmp: echo reply (DF)
22:56:16.620089 192.168.5.1 > 192.168.5.2: icmp: echo request (DF)
22:56:16.620230 192.168.5.2 > 192.168.5.1: icmp: echo reply (DF)
That works as well... So the bridge is working as well.
---------------------------------------------------------------------------------------------
Now the old experiment again:
ping 192.168.5.1 (computer2) from computer1
On soekris:
tcpdump -i wi0
22:58:32.260139 arp who-has 192.168.5.1 tell 192.168.5.3
22:58:32.260508 arp reply 192.168.5.1 is-at 0:6:5b:d7:bf:f7
22:58:33.280221 arp who-has 192.168.5.1 tell 192.168.5.3
22:58:33.280579 arp reply 192.168.5.1 is-at 0:6:5b:d7:bf:f7
No echo request/ reply. i.e. computer1 has not received the arp reply.
ping 192.168.5.3 (computer1) from computer2
On soekris:
tcpdump -i sis2
23:00:31.980133 arp who-has 192.168.5.3 tell 192.168.5.1
23:00:32.980131 arp who-has 192.168.5.3 tell 192.168.5.1
So the icmp request is not going out from wi0.
----------------------------------------------------------------------------------------------
Any ideas?
