If I reboot my compute node, the bridged network works for my guests but after 4-5 minutes it stops working, if I run tcpdump on eth0 (public) i can se icmp requests coming in but no replies, if I run tcpdump on br100 I can see icmp requests coming in and replies being sent but the traffic does not seem to makes it to eth0, any ideas?

If i do the ping from the same local subnet it works all the time, but it's traffic outside the subnet that stoppes working.

Check to see if your switching interface is going into err disabled due to spanning tree. I had this issue and had to run bpdufilter on the switching interface to stop the bridge participating in spanning tree. My switching environment is Cisco

Ive seen this before with neutron when the l3 agent changed (or multiple were running). A quick test/fix is to delete the router and recreate it. If that resolves your issue, you need to check dig into your neutron configuration.
