> I've found bug in DHCP component of VR 4.3.2. The bug is completely described at:
> https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=717217
> DHCP responses with bad checksum. As a result, dhcp client unable to get lease: "dhcpd:
5 bad udp checksums in 5 packets"
> Hotfix is:
> iptables -A POSTROUTING -t mangle -p udp --dport bootpc -j CHECKSUM --checksum-fill
> on VR.
