We have a srx300 trying to get a DHCP IP address from a modem.
The problem is that we get a local IP address in our interface when we force the DHCP Renew. EX: 192.168.100.2
We tried to make a clear: MAC - force Renew - disable interface - reboot firewall and nothing works.
On the other hand, the internet provider sees that we obtain a public IP on their side, but we in our interface always see the same IP. 192.168.100.2
what is the command to see where this IP comes from. can we reset all IPs in the interface? Is this a known problem?
To make it work, we need to placed the IP in Static in the interface and we entered the address that the ISP saw on its side afterwards we removed it and the DHCP is initialize?
Have we forgotten a starting configuration?
In our Zone DHCP is enable and in our DHCP interface is enable.
I think we have the same probleme https://forums.juniper.net/t5/SRX-Services-Gateway/SRX300-legacy-DHCP-vs-JDHCP-client-identifier/td-p/312455
