Any idea ? > How about: > > arp -s H4 auto pub > arp -s H5 auto pub not sure it can work because: 1) the netmasks for the two interfaces are overlapping, and am not sure which one is used for the "auto" address; 2) the arp table would be used for both interfaces (I think), so the router would be unable to communicate with the machines on the /24 side. I think a real proxyarp thing is needed.
