Dhcrelay don't work correctlly after network interface on which is listening is restarted (ie. /etc/init.d/net.eth1 restart) Workaround is manually run /etc/init.d/dhcrelay restart after. My working solution is to make dhcrelay init.d script depend on all network interfaces on which dhcp listen depend() { need net net.eth1 use logger } After that dhcrelay is restarted too during eth1 restart. But there is no documentation about that. Can it be in some place - /etc/conf.d/dhcrelay in IFACE parameter description? For example. # Please make init.d dhcrelay script depend on all used interfaces (net.eth0 etc.) Reproducible: Always Steps to Reproduce: 1. vlan90 on eth1, vlan1 on eth0 2. dhcrelay configured on vlan90 and vlan1 3. /etc/init.d/net.eth1 restart messages: receive_packet failed on vlan90: Network is down dhcrelay no more relays DHCP packets from vlan90 interface to vlan10

I have confirmed this bug on a tap interface.
does dhcp-4.2.1 fail too ?
(In reply to comment #4) > does dhcp-4.2.1 fail too ? yes, I make quick check in one server config: vlan1 + vlan10 + vlan90 on eth1 Mar 8 21:45:02 dhcrelay: Internet Systems Consortium DHCP Relay Agent 4.2.1 Gentoo-r0 Mar 8 21:45:02 dhcrelay: Copyright 2004-2011 Internet Systems Consortium.

should be all set now in the tree; thanks for the report! Commit message: Add suggestion to set rc_need for specific network interfaces when IFACE is set http://sources.gentoo.org/net-misc/dhcp/files/dhcrelay.conf?r1=1.7&r2=1.8
