The interface eth0:1 should be no different from a normal ethernet
interface (but it isn't eth0 itself), and the rules set up for eth0
don't apply to it, you have to create new ones, so the rules should be
interface eth0:1 ifacename
server all accept
client all accept

This happens bacause the rules you have above are being applied to
eth0 and not eth0:1. eth0 never sees traffic for that address and
eth0:1 gets the default rules (which block everything).
