Destination unreachable on DHCP renew bug

PeterUK

VPN300 V5.31(ABFC.0)ITS-22WK31-r104914

Start by a capture of a interface set to DHCP then disable/enable interface all is fine then go the monitor > traffic statistics > Interface Status and click renew for the interface now every time it does a request a ACK happens but the VPN300 send a ICMP destination unreachable (Port unreachable) for the ACK.

Hi @PeterUK

For clarify DHCP issue between client and server we need whole of the packets without filtered. (ARP/DHCP/ICMP are required)

You may share the packets in this thread or send that to me by private message.

It seems after some testing the problem only happens with one active DHCP not many
