Hi there, i’m “upgrading” my RB’s settings, assigning vlans, ip ranges, implement port knocking and etc, just got some servers to start my homelab journey, but now i’m having some problems with DHCP servers, they’re showing up in red with an “I” for inactive, and i can’t connect to internet either (my router pings google tho)

Even asked GPT-4 if he could see something that i can’t, but it didn’t help

      Actually no, i’ve fixed some thinks like the DHCP relay, and also assigned ip addresses for the VLAN interfaces, like u/SirLagz suggested, the DHCP servers seems to be working now

      I’ve bridged both management interfaces to try other approach, but i still can’t access the internet from this RouterBOARD

      I’ll leave a comment with an updated configuration script, if one of you want to take a look
