I have a CCR-2004-16G-2S+ with RouterOS 7.8. I am using a 10G RJ45 SFP to connect via PPPOE to my ISP (Bell Fibe). This configuration seems to work perfectly.
When I upgrade to RouterOS 7.9 or RouterOS 7.10, I start getting dhcp critical errors (lease expired) every 15 minutes.
I have switched back and forth between RouterOS versions and the on RouterOS 7.9 and 7.10 a dhcp client is dynamically created for my sfp-sfpplus1 [WAN] interface. In RouterOS 7.8 there is no dhcp client at all.
Is there any way to stop the dynamic dhcp client creation in the newer RouterOS versions? Or can I configure the PPPOE differently to not receive the errors?
