upgraded from 11.1R1.0 to 11.1R2.3 and my dhcp server for my internal lan and dhcp client for my ISP stop working...rolled back to 11.1R1.0 and all was working again. Anyone see the same?

When I upgraded from 10.2R3 to 10.4R2, DHCP relay stopped working for me. They fixed that in 10.4R3.
I wonder if some of the goofy DHCP code from 10.4R2 made it into 11.1R2.
You should definitely open a JTAC case on this and confirm it as a bug and get a PR issued.

Yes, this happened to me using Comcast cable internet running 11.1R2.3 for a few weeks and then my internet connection dropped and my SRX100 could no longer receive a dhcp address from Comcast. Once I rolled back to 11.1R1.10 my SRX was able to receive a dhcp address. The only problem is once I rolled back to 11.1R1.10 my HE IPv6 tunnel stopped working in flow-based mode :-(

I have an he.net 6IN4 tunnel as well. For this you just need to create a firewall filter which instructs the protocol 41 communication to your tunnel broker endpoint to be process in packet-mode. The decapsulated IPv6 packet will still be processed in flow-mode. More details in this thread starting on page 2:

found the same problem. DHCP client is working fine on 11.1R1.10 but after upgrading to 11.1R2.3 or to the newest 11.1R3.5 it stops working. Tested on SRX100.
Did anybody got answer from JTAC ?

I'm running both DHCP servers and clients without issue on 11.R2.3. The key for me was making sure that the security zone allowed DHCP on the interface I was using. I.E. "set security zones security-zone trust interfaces fe-0/0/1.0 host-inbound-traffic system-services dhcp" Once I added that, I was golden.

Exactly, I already have it working in 11.1R1.10 and the host-inbound services are permitted. After upgrading to either R2.3 or R3.5 it all breaks. I may try again to upgrade and maybe remove then reapply the host inbound services...wouldn't be the first time something like that resolves it.
