2020-01-21nat: fix dhcp client on outside interface with output featureAlexander Chernavin1-9/+9
There was an attempt to fix this problem in the commit: d3b8c861a44e70c197ab721fa3ce7f38bbeab7fd But checking the LOCALLY_ORIGINATED flag didn't work because this flag gets reset before it can reach the NAT nodes. With this commit, replace the check for the LOCALLY_ORIGINATED flag with a check to see if the packet is a DHCP broadcast.

2019-11-27nat: fix dhcp client on outside interface with output featureAlexander Chernavin1-0/+49
When a DHCP client is configured on a NAT outside interface with output feature enabled, DHCP packets will reach the NAT in2out-output node and will be dropped with "out of ports" reason. With this commit, allow locally originated DHCP packets to be sent from a NAT outside interface with output feature enabled.
