Yes, here is a tcpdump on the client machine

[root@zombie openvpn]# tcpdump -v -i tap0
tcpdump: listening on tap0, link-type EN10MB (Ethernet), capture size 96 bytes
19:32:32.112114 arp who-has 10.10.10.210 tell 10.10.10.212
19:32:33.112032 arp who-has 10.10.10.210 tell 10.10.10.212
19:32:34.111978 arp who-has 10.10.10.210 tell 10.10.10.212



Both tcpdump on br0 and tap0 yield zero results on the server side.

Joe,


No and no.  The packets stop dead in there tracks.  Also, a traceroute
yields nothing.  Goes nowhere.  Routing tables look fine.

All 10.10.10.0 traffic is set to go through tap0.


OK. traceroute may be nice, but what does tcpdump tell you when you
trace the traffic on the tap0? Do you see the traffic sent out of it?


I can ping the server assigned ip of 10.10.10.211 just fine.  Just not
the gateway.


As this works I assume that you have set both side of your tunnel to use
'tap' interfaces, right?

Cheers,
