Hi Chris,
Just wanted to ensure some basic points here.
1. Can the laptop ping the router OR any other machine in the subnet 128.171.103.0/24?
2. Also, hope that you have set the gateway of the laptop as 128.171.103.1.
regards,
Jothis

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!
