One of many annoying issues...

The old DHCP helper solution worked. The new has been a disaster.

It is great that the new solution is there for those who need subscriber
management. However, for regular enterprise DHCP relay it is
over-complex, brittle, and buggy.

It took more than 3 years to get the new code halfway-workable on the
SRX series. For the longest time we had to run a script every minute to
clear out the relay table, otherwise some legitimate replies from
servers would not be forwarded.
