Yes, this is what I tried now, using multicast_host=rl1 (instead of YES as that would configure multicast on the egress interface) and verifying connectivity via mtrace(8) between the firewalls. Still, I get dhcpd errors like the above. > And of course there shouldn't be a firewall blocking the multicast traffic. The firewalls are on the same subnet, and mtrace tells me they are directly connected. -- Zak B. Elep || orangeandbronze.com 1486 7957 454D E529 E4F1 F75E 5787 B1FD FA53 851D
