Maybe folks need more information on your network topology; ifconfig,
netstat -rn, say .. tcpdumps on the interface losing traffic?

I haven't used redirect_address, but perhaps you need to specify
target_address to disambiguate requests to other than alias_address?

Stab in the dark, since it was my bright idea to refer you to -net :)
