Hi List,
I have setup a bridge labeled br0. br0 has an ip address assigned to it. My
network looks something similar to this...
|--------------------| |--------------------|
|------------------|
| laptop | | bridge |
| router |
| 128.171.103.10/24 | -----> (eth1)| 128.171.103.11/24 |(eth0) ----->
| 128.171.103.1/24 |
| statically assignd | | statically assignd |
| tested / working |
|--------------------| |--------------------|
|------------------|
Now for the PROBLEM! The bridge can access IP's outside of the subnet via
eth0 of the bridge, ie - pinging 128.171.1.1, 128.171.3.13, 64.233.167.99.
The laptop cannot ping the previously listed IPs. The only thing the laptop
can ping is 128.171.103.11. It's very odd... I tried running tcpdump on the
bridge. From the bridge I could see the laptop pinging the bridge but I
couldn't see the laptop pinging any other IPs. So basically I have a bridge
that's not really working but the bridge utils show that its working... any
help would be greatly appreciated!
(The laptop works when taken off the bridge and connected to the router, the
iptables default policy is ACCEPT and the rules are FLUSHED.)
Thanks for taking time to read this!
