Android and DHCP
-
Only Android phones…
-
Yes. And?

I would agree if the issue is with only one device. But when you try with 2-3 devices and the result is the same I guess some digging would help…
Other devices work as expected. I don't think PFSense is the problem, I just want to get some suggestions, maybe something I have overlooked. -
The phone sends DHCPREQUEST, gets DHCPOFFER, then it refuses that… Dig into your phone/Android.

"dhcpd: DHCPREQUEST for <android_generic_ip>(<android_generic_ip_broadcast>) from <android_mac>via em1: wrong network."
So its doing a request for wrong network?? Its so much easier to just see the sniff vs log, that your obfuscating mac addresses??
What IP is it asking for, did a ping go out and it comes back with an answer from your gateway??
"unexpected ICMP Echo Reply from <wan gateway="">"</wan></android_mac></android_generic_ip_broadcast></android_generic_ip> -
What IP is it asking for, did a ping go out and it comes back with an answer from your gateway??
"unexpected ICMP Echo Reply from <wan gateway="">"</wan>That part's just a quirk of dhcpd's listening, it sees gateway monitoring ping replies. Doesn't hurt anything as it just ignores it and log spams.

So much better to just sniff and see exactly what is going on, what gets requested, what gets offered, etc. etc..

Guys, thank you all for your ideas.
I solved the issue and I am happy to say that both Android and PFSense have no issues (it was kind of clear from the beginning).
The problem here was VMWare Workstation, let me explain: I use my desktop as a home lab and have a some network interfaces that I bridge in order to get all the networks I need. I did the whole config on Win 8.1 but when I migrated to 10, for some reason, it did not migrate the networks correctly and I had to redo them. It seems that even after this was done, there was one more issue. Workstation started the DHCP and NAT services in Windows, services that I had stopped and selected to start only manually.
For some reason DHCP was started and using VMNet1 as a custom network with IP 192.168.209.x/24 and some wireless devices went to this DHCP server for leases. It's interesting because VMNet1 is bridged with my LAN 10.10.0.X/24. The only way I can see the weird interface was if I used Virtual Network Editor without admin right (start Workstation not as an admin but as a normal user, screenshots attached). Screenshot 1 is taken without admin rights and screenshot 2 with admin rights and as you see they both have VMNet1. Windows does not report that virtual interface but for some reason it was there giving out IP leases. After I stopped Workstation DHCP service, everything is running smoothly.
Sorry for the long post and thanks for all your help.
Best regards,
Andrei

In future, you might want to mention this little nugget a little sooner. Virtualized installs add a whole other level of details & troubleshooting.

The network was hidden even with ipconfig /all so I didn't really know, only after some troubleshooting.
