I am using double NAT, I can not put my provider provided modem in bridge mode so I put my unifi USG in it´s DMZ.
On my USG I set up forwarded ports, before I migrated my subnet away from a 10.0.0.0/8 subnet (I had to create a Work vlan as I had IP conflicts with the work vpn) to a 192.168.0.0/22 subnet I could access my public IP from inside my network and outside.
After switching subents I can only access it from outside. I heard of NAT reflection but I can not find the settings in the USG and I had not changed anything in that regard. My unifi usg seems to drop it.
Tracing route to home.my.domain [<myPublicIP>]
over a maximum of 30 hops:
1 <1 ms <1 ms <1 ms gateway [192.168.0.1]
2 * * * Request timed out.
3 * * * Request timed out.
4 * * * Request timed out.
Is it because now the modem and unifi are part of 192.168.0.0/16?
Old unifi subnet: 10.0.0.0/8 I know it was way too large
New unifi subnet: 192.168.0.0/22
Old modem subnet: 192.168.1.0/24
New modem subnet: 192.168.255.0/24
