WAN DHCP from isp issue

[Omerav]

Hi Guys,

i have an R790 Self managed FW with dual ISP configured.

since yesterday one of the ISPs connection which is using a DHCP is returning the following error:

WAN Received the IP address which is part of an internal network or static route rule. and can't get an IP from the ISP.

ISP checks and said everything is fine on his hand.

i restarted both the FW and ISP Bridge with no luck.

help will be appreciated

Did you change anything before that happened 😉 ? What about logs,  is an error with the IP shown in WebGUI and/or /tmp/messages ?

I believe that error shows up when DHCP on the WAN side is assigning you an IP in the same range you serve up on your LAN interfaces.
Change the internal LAN subnet to something different.
