Greetings all. Upfront, I'm a beginner at best with a homelab, so you know where my skillset is at. I've been around networks for a while, just never worked on them beyond the off the shelf stuff. I started to take my CCNA a few years ago, passed the first test, but never went back (life, work, family, etc). So I'm not unfamiliar with them, and I think I understand fundamentals (maybe).
The issue I'm having right now is trying to get IP leases from remote DHCP's.
My equipment
MikroTik RB4011 router (where I want the DHCP servers)
Cisco 3560X 48 PoE+ w/ the 10Gig module
A Unifi AP AC Pro
Dell R630 running some VM's
The SFP+ port on the MikrotTik and 3560X are in a routed, no switchport, non-trunk mode
I had originally thought my issue was on the RB4011. The Cisco is setup to do Inner VLan routing, and it's doing it perfectly (a network buddy of mine helped me set it all up, teaching me a few things along the way). The RB's only job is to connect ether 1 to my modem/internet and the SFP+ to one of the 10G uplinks on the switch. Works great. We did not do RoaS as I wanted the switch to do all the heavy lifting for inner routing, leaving the router to worry about firewall, passing traffic to the internet, and DHCP services for the VLans. Everything in my house is connected to the 3560X. With the exception of a couple items, we currently have everything in VLan 1 just to keep it simple until I get the DHCP issue sorted. My gear (eg; the Dell R630, the AP, my desktop) are all in another VLan (150) and all working perfectly.
VLan 1 and 150 are using the Cisco as their DHCP. VLan 165 is my "test bed", a laptop. I will end up with 5 VLans when all is done.
My intent had been to use the MikroTik as a DHCP, and even though everyone on VLan 1 and 150 could ping each other, get out to the internet, etc., I couldn't pull IP's on VLan 165 (ip helper-address was pointing to the IP on the MT, and packet sniffer could see traffic). I static assigned an IP to the test laptop in VLan 165 and it worked great, so it's not a routing issue. After researching for the last week, I finally gave up on the MT and decided I would go ahead and use my Unifi controller as the DHCP server. I configured it, pointed the ip helper at it and wha la - nothing.
Same issue. Can talk to it all day, can talk from it, but no IP's are being issued.
None of the DHCP's are on the same subnet, but from what I gather, that doesn't matter so long as the ip helper is pointing to the correct IP that's running the DHCP?
Is there a possibility the request is being blocked? Is there a config setting I need to turn on? I checked the Cisco documentation for relays and found nothing other than the ip helper, which again, seems to do it's job of sending out (every time I did an ipconfig /renew on the laptop, packet sniffer on the MT count would go up, then stop when the laptop would give up).
I'm attaching my config, vlan, and ip route. I believe I redacted all the important stuff.
If anyone can give me any clues. At this point I don't know if I need to be looking at the MikroTik, the Unifi Controller, the Cisco, or all three. My buddy tries to help where he can, but he's a seriously busy man with young young'ns, so I try very hard not to bother him. I'm at a total loss.
One last note, I'm definitely not asking anyone to spoon feed me answers, but I know so little that at this point, I don't know if what I'm trying to do will even work. If someone could tell me that I'm banging my head on the wall for nothing, I'll stop, give in, and go the RoaS route (no pun). And if it can be done, just tell me what I need to read up on/look at, the key points to watch for.
If you made it here, thank you for taking the time to listen to my plea lol. If you offer up any answers/suggestions, right, wrong, whatever, I thank you for trying to help.
